45 tools
add_dependency
Add Dependency
Add npm packages to the project (validated against Floot's supported set — rejected packages get a supported alternative named; some versions are pinned/substituted). Avoid node-gyp/native packages (exception: sharp is supported, auto-pinned), WASM modules, and packages bundling large binaries (e.g. ffmpeg/ffprobe); pure JS/TS preferred. A bare `kysely` installs 0.26.3, the version the generated db/schema helpers are written against; pass an explicit `kysely@<version>` only when upgrading it deliberately. Installs on the project VM and persists resolved versions. After a slow install completes as a job, call add_dependency again with the same packages — the second call is fast and persists.

apply_patch
Apply Patch
Apply a V4A patch to a Floot project — create, update, and delete multiple files in ONE atomic operation. Format: "*** Begin Patch" envelope with "*** Add File: path" (+ prefixed lines), "*** Update File: path" (hunks: optional "@@ anchor" locator, space-prefixed context, -/+ lines, optional "*** End of File"), "*** Delete File: path", then "*** End Patch". Paths follow the Floot item scheme (see read_file). To replace a file wholesale use Add File on its own — Add OVERWRITES. Never Delete+Add the same path: Delete is item-scoped (deleting components/X.tsx deletes the whole item, its .module.css included), so it is both unnecessary before an Add and destructive to the siblings. Move to: is not supported — to RENAME, Add File at the new path and Delete File the old one. Keep each patch MODEST (a few files / few hundred lines): chat clients cap per-message output, and a patch cut off mid-way is rejected whole ("missing *** End Patch") — split big changes across several apply_patch calls.

cancel_request
Cancel Request
Withdraw a pending request you created — a credential request from request_external_resource, a custom-domain setup request from publish_app, or an open screenshot job from screenshot_preview (jobId from that tool). Only pending requests can be cancelled — completed ones are final. Use when the user says to stop or they don't want to proceed.

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['projectId', 'jobId'], 'properties': {'jobId': {'type': 'string'}, 'projectId': {'type': 'string'}}, 'additionalProperties': False}
card_upload_asset
Upload Card Bridge
Internal bridge for the upload card (not for agents — use request_user_upload / upload_asset). phase 'presign' mints the PUT URL for the picked file; phase 'complete' verifies the object landed and finishes the request_user_upload call with the publicUrl.
Input schema

copy_file
Copy File
Copy one or more items to new names (e.g. {from:'components/Card', to:'components/BigCard'}). Item names without extensions; same type only. Importers of the source are left unchanged. Pass several copies to apply them in one call.

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['projectId', 'copies'], 'properties': {'copies': {'type': 'array', 'items': {'type': 'object', 'required': ['from', 'to'], 'properties': {'to': {'type': 'string'}, 'from': {'type': 'string'}}, 'additionalProperties': False}, 'minItems': 1}, 'projectId': {'type': 'string'}, 'expected_version': {'type': 'integer'}}, 'additionalProperties': False}
create_checkpoint
Create Checkpoint
Create a NAMED checkpoint — a labeled restore point the user sees in the project's Checkpoints panel and can revert to later. All file/dependency changes since the previous checkpoint are grouped under it. Call this AFTER completing a coherent unit of work (a feature, a fix, a requested change set) — not after every file write. Give it a short user-meaningful title describing what was accomplished (e.g. 'Added login page with email auth'), optionally a description with detail. No-op when nothing changed since the last checkpoint. Restoring a checkpoint reverts code and project config only — database rows, uploaded assets and published deployments are not rolled back.

create_project
Create Project
Create a new Floot project (pre-seeded with the shared component library) and return its id. `initial_prompt` is the USER'S ORIGINAL REQUEST verbatim — it grounds the project (served back as <project-instructions> in list_files) and is preserved for the record; don't paraphrase it away. The result renders a live preview card for the user and includes the first-build playbook: a fresh project is EMPTY until pages are written, so a session normally continues straight into get_guides("design") and the first page rather than ending at the card.

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['name', 'initial_prompt'], 'properties': {'name': {'type': 'string', 'maxLength': 80, 'minLength': 1}, 'initial_prompt': {'type': 'string', 'maxLength': 16000, 'minLength': 1, 'description': "The user's original request that started this project, verbatim."}}, 'additionalProperties': False}
delete_file
Delete File
Delete a project file. Deleting an item's main code file (e.g. components/Foo.tsx) removes the whole item including its css/tests; deleting an aux file (e.g. Foo.module.css) only clears that part.
Destructive

edit_file
Edit File
Replace old_string with new_string in a project file. old_string must match the current content exactly (including whitespace) and be unique unless replace_all is set. Prefer this over write_file for changes to existing files.

execute_sql
Execute SQL (Writes)
Run a WRITE SQL statement against the project's Postgres database — CREATE/ALTER TABLE, INSERT, UPDATE, DELETE, DROP, migrations. Destructive statements are allowed but your MCP client will show the user the SQL and ask them to approve it (they can allow once or for the session). Schema-changing statements (CREATE/ALTER/DROP of tables, types, …) automatically re-pull the typed schema helper and return the updated schema — no separate pull_database_schema call needed. Pass `database` only if the project has more than one. The query runs in a single transaction by default; set no_transaction for statements that cannot run inside a transaction block (VACUUM, CREATE INDEX CONCURRENTLY, …). Queries are killed after 90 seconds either way.

fetch
Fetch Search Result
Fetch a search result by id: a project overview ('<projectId>') or a file ('<projectId>:<path>'). For direct access to a known file or project, read_file/list_files give more detail.

generate_image
Generate Image
Generate AI image assets directly into the project. Each image is written to the project's own asset storage and registered in its asset manifest; the tool returns the project-relative asset paths (/_cdn/static/...), which only resolve on the app's own domain — reference them in code or set one as the app/PWA icon via update_project_metadata (iconUrl). Use this for PROJECT-SPECIFIC imagery (mascots, tailored illustrations, app/PWA icons, imagery in a particular style); for generic stock imagery (nature, textures, generic people) use Unsplash URLs instead; if you already HAVE an image as a local file (generated or downloaded yourself), use upload_asset. Generate BEFORE building the components that use the images.

get_current_context
Get Current Editor Context
What the user is looking at RIGHT NOW in their open Floot editor: the active page/component, the preview element they selected (mapped to source file:line), the preview device size, whether they drew a screenshot annotation for you, whether they REVERTED recent changes (undoing edits — re-read before editing if so), and any requests they queued via editor action buttons ("Fix with Floot" etc.). Call this FIRST when the user refers to something without naming it ("this", "here", "the button"), reports a problem without saying where ("it's broken", "looks wrong"), or implies they triggered something in Floot ("go", "I clicked fix", "I undid that"). Cheap and text-only. With several windows open, one answers (the result says which) — but a selection made in ANY window is merged in, so a "no selection" from the answering window plus a deposited selection from another window means the deposited one is what the user means. If it reports a pending annotation, call view_annotation to see the image.

get_guides
Floot Guides
Floot documentation for agents. Call with no arguments to list available guides. Pass `topic` for one guide (e.g. topic:'floot-overview') or `topics` (an array of ids) to fetch several at once. floot-overview explains how Floot projects work — read it before your first code change. Skill guides that ship seed code (marked in the list) AUTO-INJECT it into the project the first time they're loaded with a projectId — pass projectId whenever you're working on a project; idempotent, never overwrites existing files.

get_job_status
Get Job Status
Poll a pending tool call by its jobId. Each poll either returns the final result (succeeded/failed/cancelled), or reports the call as still running — call it again until you get the result. Failed calls return their stored error message. A jobId belongs to exactly ONE task: it never blocks other tools or other jobs (run them freely in parallel), and once terminal it is frozen history — a NEW user request means a fresh call on the originating tool, never re-polling an old jobId. Legacy v!/b! job ids are also accepted.

get_logs
Get Logs
Your FIRST step when debugging any runtime problem — a 500, a failed request, a blank page, or 'it doesn't work' from the user. Call this before theorizing from an error message alone. Reads the project's runtime logs. source 'server' (default): the dev backend's request logs from the last hour — method, URL, status, duration, and per-request server log lines (pass log_reference_id from a previous listing for one request's full logs); includes background jobs (queueTask/scheduled/failure). source 'browser': console output AND client-side network requests (each fetch as `⇄ METHOD url → status`, with the error body for failed/4xx/5xx ones — the client-side view server logs miss, e.g. CORS/timeouts/third-party calls) captured from the user's open editor session. A browser network line's `ref=<id>` is a log_reference_id you can pass back with source 'server' for that request's full server logs. Empty if no editor is open. NOT CloudWatch: entries live ~1 hour and cover the dev backend + live session only — for the PUBLISHED app's logs, use run_code_in_vm's `_floot.getProdBackendLogs` (details: get_guides('prod-backend-logs')).

get_preview_url
Get Preview URL
Show the user a live preview card and return the preview link. On an EXISTING project this is typically called EARLY, before the first change, so the user watches edits live from the start; the result is informational and a working session normally continues past it. Do NOT call it right after create_project — that result already showed the same card; calling both duplicates it. The preview URL carries an access token in its query string and only works shared EXACTLY as returned (no Floot login, view-only — which is also what lets it open on a phone); it live-updates as you edit, so it also suits an in-app browser tab if your client has one. The result additionally includes the sandbox API base for your own headless /_api/* testing — the frontend does not render there and it is not a user-facing URL; the preview link is the one meant for the user. Floot HOSTS the app — to go to production use publish_app; never suggest deploying a Floot app to an external host.

get_publish_status
Get Publish Status
Read-only publish snapshot for a project: published (true/false, with the live URL when published), customDomains (the user's own domains attached to the project — apex and www are listed separately; empty when none), paid (the workspace owner has a paid plan, which allows removing the Floot badge), plan (free | pro | power — `paid` cannot tell Pro from Power), nativeBuilds (the owner's remaining monthly iOS/Android app-build allowance; `unlimited` is true on plans where the ceiling is only a fair-use backstop, and while an Action Boost is live (`boostUntil` says until when; builds started before then never count toward the allowance) — read this BEFORE passing mobile: true, and on a metered plan build only when the user asked for a native/TestFlight/Play build), displayFlootLogo (whether the live app shows the 'Made with Floot' badge; true until a paid owner turns it off), and mobileBuild (the project's latest native app build: building, succeeded, or failed with what to fix; isMobileTestMode marks a mobile test build — an app build finishes minutes AFTER the publish job it rode on, so read this to learn how it ended before telling the user it worked). This is the ONLY tool that reports attached custom domains — read it before telling a user whether their domain is connected, and never conclude a domain is unattached from any other output. The publish card calls this on load to render fresh state; also check it before publishing to know whether publish_app will publish fresh or publish the live app again.

list_files
List Project Files
List a Floot project's virtual file tree with sizes, plus its dependencies, current version (pass the version to write tools as expected_version), and current project metadata — title, description, app icon (iconUrl), splash screen, mobile app id, SSR, iOS Info.plist overrides, share target (iOS + Android), native system bars. This is where to look up those settings; update_project_metadata changes them.

list_projects
List Projects
List your Floot projects (id, name, last-updated, whether an app icon is set), most recently updated first. name_filter is a case-insensitive substring match on the stored name, which is often not the name the user uses for a project — on a small account a filter that matches nothing returns the whole list instead.

list_resources
List Available Resources
List the env vars a project's code can use and the resources behind them: (1) resources CONNECTED to the project — usable as process.env.<NAME> in endpoint code now; (2) the owner's other account-level credentials — reusable, but not usable in code until connected; (3) everything Floot can add. Call it to learn what env vars exist before writing backend code, and BEFORE provisioning or requesting any credential (the owner may already have the one you need). Pass query (case-insensitive substring over names, descriptions, types, and env var names) to filter when the account has many resources. Read-only. Details: get_guides('resources').

navigate_preview
Navigate the User's Preview
Point the user's OPEN Floot preview at a page URL, a component's examples, or a page's examples — use it to SHOW the user what you just built ("here's the new dashboard page", "here's the Button component's states"), and pair it with screenshot_preview to see the result yourself. targetType "page" navigates the app's router to `path` — a URL path with optional query/hash ("/", "/user/123?tab=settings#top"; pages/user.$id.tsx serves /user/<id>). targetType "component" renders the component's .example.tsx showcase for `name` ("HeroSection", exactly as list_files shows it; tell the user if it has no example — you can create one). targetType "page-examples" renders the staged screens in pages/<name>.__example.tsx for the page `name` ("dashboard", "_index") — the same view as the preview's Live/Examples switch, so it needs that file to exist. Requires a Floot window to be open for this project; fails fast with guidance when none answers. Does not modify the project.

provision_resource
Provision Resource
Provision a Floot-managed backend resource for the project — fully server-side (Floot mints all secrets; no keys to paste). Also seeds the working code for it. Available: - database — A Floot-managed Postgres database (Neon). FLOOT_DATABASE_URL is set for the app. - auth — Email/password + session auth (JWT_SECRET, auto-provisions a database if none). Injects auth pages, endpoints, and helpers. - oauth-login — Sign in with Google via Floot's brokered OAuth (FLOOT_OAUTH). Injects OAuth provider classes, login buttons, helpers. - microsoft-login — Sign in with Microsoft via Floot's brokered login (FLOOT_MICROSOFT_LOGIN). Injects button + auth endpoints. - google-integration — FLOOT_GOOGLE_INTEGRATIONS is our built-in Google integration. Use it to let end users connect their Google account so the app can read/write their Gmail, Google Calendar, or Google Drive — unless the user specifies they want to use their own Google client. See get_guides("floot-provided-google-integrations"). - microsoft-integration — Microsoft Graph access (Outlook/Teams/etc.) via Floot's brokered Microsoft OAuth (FLOOT_MICROSOFT_INTEGRATIONS). Injects Connect button + endpoints. - push-notifications — Web + native push (FLOOT_PUSH). Mints VAPID keys, injects helpers/pushClient (subscribe/unsubscribe) + a service worker. Enum values not listed above are beta-gated and unavailable on most accounts. SENDING email from the app is NOT a resource — the builtin @floot/email handles it with zero setup (get_guides("email")). For a user's OWN external key (their OpenAI key, an external database), this is NOT the tool — use request_external_resource instead. Idempotent: re-running returns the existing resource and skips seed files that already exist.

publish_app
Publish App
Publish the app to production — call for the first publish, to publish again after changes the user wants live, and to set up a custom domain. Omit domain and the user gets the publish form in the editor. Pass mobile: true whenever the user mentions iOS, Android, TestFlight, App Store, Google Play, or a mobile/native app — with no store account connected that returns a Connect card; with one connected it publishes with the store builds attached. When the project takes payments and its owner has not finished Stripe setup, the publish is refused and a Set up payments card is returned (nothing published): tell the owner to click the button on the card and finish Stripe setup, then call publish_app again. publish_app always publishes live (web, and the mobile app when it is built; payments in Stripe live mode) — never ask the user test or live. Mobile test builds are started by the user on floot.com. Read get_guides('publishing') for modes, inputs, and statuses before your first call.

pull_database_schema
Pull Database Schema
Introspect the database and write a typed schema helper the app uses for queries (kysely on current projects; some legacy projects use drizzle or snake_case kysely — the pull matches whatever the project already uses). Usually NOT needed after execute_sql — schema-changing statements re-pull automatically. Use it to refresh manually, or with helper_name to generate the helper for an additional/external database. The helper is GENERATED — never hand-edit it or cast around its types: if a column's type is too loose (e.g. role as string when code expects "user" | "admin"), fix the DATABASE (CREATE TYPE … AS ENUM + ALTER COLUMN … TYPE) and re-pull, and the union type falls out.

query_database
Query Database (Read-Only)
Run a READ-ONLY SQL query against the project's Postgres database (SELECT, EXPLAIN, etc.). Writes are rejected — use execute_sql for those. Returns JSON: `{rows, rowCount, command, truncated?}` (or `{results: [...]}` for multi-statement queries). Pass `database` only if the project has more than one.

read_file
Read File
Read a file from a Floot project (cat -n style). Paths follow the item scheme: components/Name.tsx, components/Name.module.css, helpers/Name.tsx, pages/name.tsx, pages/name.pageLayout.tsx, endpoints/route_POST.ts, endpoints/route_POST.schema.ts, static/file.txt, base.css. Use offset/limit for large files. Pass include_references:true to also list which project files reference this one (static import graph plus queueTask/runCode name references and, for endpoints, URL-path string usage) — check it before renaming or deleting a file, or use rename_file which rewrites importers itself. Hosted assets are readable too: pass the project-relative asset path (/_cdn/<name>, as returned by upload_asset / generate_image or used in the app's <img src>; private/<name> for private storage) and a png/jpeg/gif/webp image is returned as an image you can see (≤3.75 MB), text-typed assets as text, other binaries as a size/type summary. For a .ts/.tsx file, the file's CURRENT type errors are appended when the project's compute VM is already warm (so you see latent errors before editing); pass diagnostics:"off" to skip, or "wait" to boot the VM and force the check. older_than walks the file's HISTORY: pass "current" to see the file as it was just before its latest change, then the cursor from that result to step one change further back — use it when something used to work and you want to compare or restore an earlier version (write the old content back with write_file).

read_files
Read Files
Read MULTIPLE files from a Floot project in ONE call — much cheaper than repeated read_file (the whole project is loaded once, one round-trip). Prefer this whenever you need several files together (e.g. an endpoint + its .schema.ts + the hook that calls it, or orienting in a feature). Pass up to 20 paths (same item scheme as read_file; /_cdn/<name> asset paths are accepted too and images come back as image blocks). Each file is returned cat -n style under a header. Each .ts/.tsx file's current type errors are appended when the compute VM is warm (diagnostics:"off" to skip, "wait" to force). include_references:true appends each file's referencing files (same analysis as read_file). Output is capped overall; if the batch is too large, whole files at the end are omitted and listed by name so you can read them individually. With older_than (up to 5 paths) the files are walked back through history TOGETHER on one timeline — the way to keep a component and its stylesheet consistent.

rename_file
Rename File
Rename one or more items and automatically rewrite every file that imports them. Use item names WITHOUT extensions (e.g. {from:'components/OldName', to:'components/NewName'}). Preferred over delete+create — preserves content and fixes importers. Same type only. Pass several renames to apply them atomically in ONE pass; importer rewrites are resolved across the whole batch (including chains where one rename's target is another's source).

request_external_resource
Request External Resource
Request the USER'S OWN external credential for this project — their OpenAI or Anthropic API key, an external Postgres connection string (ALWAYS type POSTGRES — a Postgres credential requested as GENERIC is refused, because only POSTGRES gives the user a database: the Databases tab, helpers/db, the typed schema and query_database), or any other service's key (type GENERIC, e.g. Stripe/Resend — secret_env_vars is REQUIRED for GENERIC and the call is refused without it; a var the user can only produce LATER, like a webhook signing secret, goes in optional_env_vars so the dialog doesn't demand it up front). NOT for Floot-managed resources (database/auth/push/oauth/…) — use provision_resource for those; they need no user input. REUSE FIRST: if the project owner already has a matching credential on their account (list_resources section 2), this connects it silently and returns the env var names — no link, no user action, nothing to poll. Pass the name exactly as list_resources shows it to make that happen. Reusing a POSTGRES credential also seeds helpers/db, installs the query stack, and pulls the typed schema helper, so do NOT write those yourself afterwards. Otherwise it returns a secure connect link: SHOW it to the user (UI-capable hosts render a Connect button automatically; on terminal hosts with shell access open it in the user's default browser yourself and paste the URL as plain text) and ask them to open it. The call completes only when the user finishes the connect flow — it never expires. Do NOT block on it: request the credential EARLY, keep building everything that doesn't need the secret (the env var names are known now — reference process.env.X in code before the secret exists), and check the request between tasks; the user may never connect it, and the build must not stall. NEVER ask the user to paste a secret into the chat. On completion you get the env var names — never the secret values. Re-calling with the same type returns the same pending request. If the credential is already connected and holds every value you asked for, you get those env var names and their value SHAPES back immediately and the user is not interrupted — to reopen a dialog because a stored value is wrong, re-call with `instructions` saying what is wrong.

request_user_upload
Request a File From the User
Show the user an inline upload card so they can hand you a file from their device (image/font/audio/…) — it lands in the project's hosted assets and the card gives you the hosted publicUrl. This is the path for any file the user has: an image they attached in this chat (attachments never reach MCP servers — you see them through vision only, so the user re-picks the same file here), a file on their machine, or a user-provided file you hold but can't upload yourself (over the 3 MB inline cap with no S3 egress — the card uploads from their browser, which is never egress-blocked). Returns a jobId — poll get_job_status; it stays running until they upload, then returns the publicUrl to reference in code. When you show the card, tell the user in a sentence why you're asking — e.g. that you can see their image but the file itself doesn't reach Floot, so re-adding it here is a one-click step — and ask them to say "uploaded" when done in case your polling ends before they finish. For files you hold yourself, use upload_asset; for AI-generated imagery, use generate_image.

run_code_in_browser
Run Code in Browser
Run a TypeScript snippet inside the RUNNING APP's preview document in the user's open Floot editor (`document`/`window` ARE the live app's DOM — query `document` directly; do NOT look for a preview iframe, there is none from the snippet's point of view). This is the CANONICAL way to read the live app's DOM — measuring elements, reading computed styles, inspecting rendered output. If you ALSO have your own browser/DevTools automation, it CANNOT reach into the Floot preview (it renders in a cross-origin iframe — your clicks silently no-op and its DOM is invisible to you), so use THIS tool for anything inside the app, not those. `_floot.*` helpers are available. The snippet MUST `export default async function` and return a string — the returned value is the tool result (unlike run_code_in_vm, which is a plain script returning stdout). It can import project files by relative path from the root (e.g. `./helpers/foo`). Requires the user to have the project open in the editor — fails fast with guidance if no browser is connected; prefer run_code_in_vm for anything that doesn't need the DOM. Simple interaction checks work well: element.click() a button, await a beat, then read the resulting DOM/state to verify a flow end-to-end — do this instead of asking the user to test basic interactions. Multi-step e2e journeys and typed text input are where simulation gets unreliable (React controlled inputs ignore assigned values) — leave THOSE to the user.

run_code_in_vm
Run Code in VM
Run a Node.js snippet on the project's compute VM (headless — no browser needed). The project's npm dependencies are importable; network access works, so you can call the project's /_api/* endpoints (get_preview_url → apiBaseUrl). ESM by default; bare require() snippets run as CJS. Returns stdout+stderr. Calls to the project's /_api/* are rate-guarded exactly like the browser preview: more than 20 calls to one endpoint or 150 total within 5s rejects that fetch and every later /_api/* fetch in the snippet with 'Backend endpoint is called too frequently'. This is a hard guard, not a retry hint — do NOT loop fetch() over rows/ids or fire many parallel calls; batch into one endpoint call, or use _floot.runSQLQuery for bulk reads/writes. Runs in an ISOLATED temp dir, NOT the project root, with NO access to the project's environment: `process.env` carries none of the project's env vars or secrets (only PATH/HOME/NODE_ENV are set — anything like `process.env.POSTHOG_API_KEY` reads back `undefined`), and project source files are NOT importable by relative path (`import './helpers/foo'` fails with ERR_MODULE_NOT_FOUND — only npm dependencies resolve; contrast run_code_in_browser, which runs at the project root and CAN import project files). For anything that needs project secrets, env config, or DB access, use the `_floot` helpers below (they proxy to the project's server context) or fetch the project's /_api/* endpoints over the network — those run server-side WITH the full env; the VM snippet itself never sees it. A `_floot` global is available with project-scoped server-data helpers (no DB creds needed, no HTTP wiring): `await _floot.runSQLQuery({ query, resourceName?, reasonAndExplanationForNotReadOnly?, dryRun? })` (omit the reason for a read-only query; pass it to allow NON-DESTRUCTIVE writes — INSERT, CREATE TABLE, additive ALTER — e.g. programmatic seeding loops. DESTRUCTIVE statements — DELETE/UPDATE/TRUNCATE/DROP — are rejected here because the user never sees snippet SQL; run those through the execute_sql tool, where the statement appears in the tool call for approval. Resolves to `{rows, rowCount, command, truncated?}` — or `{results: [...]}` for multi-statement queries), `getHostingUsage({days?})`, `getLambdaUsage({days?})`, `getPushHistory({subscription?,from?,to?,offset?})`, `getProdBackendLogs({filter?,from?,to?,nextToken?,limit?})` (the PUBLISHED app's backend CloudWatch logs; details: get_guides('prod-backend-logs')), `storageList(prefix)` (prefix MUST start with "public/" or "private/" — e.g. storageList("public/") to list everything public), `storageGetUrl(key)`, `storageGetFileSizes(visibility, continuationToken?)`, `storageUpload({filename,sizeBytes,contentType})`, `storageDelete(key)`, and `getFileById(id)` (returns `{url, fileName, contentType}` — fetch the url for bytes). Same surface as runCodeInBrowser's `_floot`, minus the DOM/editor-only helpers.

run_tests
Run Tests
Run the project's Jasmine spec files (helpers/*.spec.tsx) headlessly on the project VM (jsdom — no browser needed). Frontend AND backend code is testable: specs may render components (@testing-library/react) or import endpoint handlers/backend helpers and call them directly. Limits: fetch throws inside tests (mock with spyOn(globalThis, "fetch")), process.env secrets are absent, and specs importing @floot/* service modules are skipped (no mocks yet). Returns per-file PASS/FAIL with failing expectations. Defaults to all spec files except hook specs (file name contains "use" — those need real React scheduling and are excluded, matching the in-editor checker); pass `paths` to run specific spec files, including hook specs.

screenshot_preview
Screenshot the User's Preview
Capture a screenshot of the user app. Call it whenever you want to SEE what the app currently looks like (layout, styling, rendered state) or want to debug the app. By default it shows whatever device the user has the preview on. Pass `viewport` to see it on another device — this is how to check a mobile or tablet layout: the preview switches to that device for the capture only, then back.

update_project_metadata
Update Project Metadata
Update project settings (current values appear at the top of list_files). Keys: title (2-100 chars), description, iconUrl, splashUrl, mobileAppId, enableSSR (boolean), flootAiDisallowed (boolean — true opts the project out of @floot/ai), and iOS Info.plist purpose strings (NS…UsageDescription — set to a string, or null to remove) plus boolean Info.plist keys (UIViewControllerBasedStatusBarAppearance — set to a boolean, or null to restore the template default). Invalid keys/values are reported and skipped. NOTE: these take effect on the published app only after the next publish (publish_app, or the user's Publish button). The iosInfoPlist keys only affect builds made before the first iOS publish; after the iOS app is published, edit the project file `static/__dev/native/ios-info.plist` directly with write_file/edit_file (see get_guides('ios-info-plist')). Likewise, after the first Android publish, edit `static/__dev/native/android-manifest.xml` directly for manifest changes (see get_guides('android-manifest')). `shareTarget` makes the native app appear in the iOS and Android share sheets (other apps can share photos/videos/files/text into it): pass { enabled: true, mimeTypes?, allowMultiple? } to register, { enabled: false } to remove; receiving the shared items still needs the handler in app code — read get_guides('share-target') first and ship both together. `nativeSystemBars` controls how the native app treats the status bar / Android navigation bar: mode 'inset' (default) keeps the app below the bars and paints the exposed strips `color` (default black — set it to the app's header color for a seamless look); mode 'edge-to-edge' runs the app under the bars, which REQUIRES the app to pad by var(--safe-area-inset-top/bottom) itself — read get_guides('native-system-bars') first and ship both changes together. Not superseded by the __dev/native files. `serverMemoryMb` sets the memory (MB) of the project's server Lambda, which runs every endpoint, queued task, scheduled job and SSR render (default 1024 MB; 2048 for the published app when SSR is on — the dev backend never bumps). EXPERT SETTING — NEVER change it on your own initiative or as a side effect of another request, only when the user explicitly asks to change the server memory AND understands the trade-off: too low and the backend stops working entirely (killed out-of-memory); Lambda CPU scales with memory, so a lower value also makes every request slower and — because compute is billed per GB-second of billed duration — can cost MORE, not less; a higher value costs more per millisecond. Allowed range 512–4096 MB, whole MB (if a size turns out not to be available for the app's server, the deploy fails and the error names this setting). It applies to the dev backend at the next backend deploy and to the published app at the next publish. Pass null to restore the default. Read get_guides('server-memory') before changing it. `analyticsMode` controls the built-in visitor analytics tracker every published app includes (the project's Analytics tab): 'storage' (default) keeps a 30-minute session id in the visitor's localStorage, which is device storage that needs consent under EU ePrivacy / UK PECR — an app with EU/UK visitors pairs it with a consent banner that calls window.flootAnalytics.setMode(); 'memory' keeps the id in memory only (nothing stored on the device, no consent needed, but a reload or new tab counts as a new session); 'off' sends no analytics at all. Only change it when the user asks about analytics, cookies, consent or privacy for their published app; it takes effect at the next publish. Read get_guides('analytics') for the consent-banner API before changing it. `iosDeviceFamily` picks the devices the native iOS app is built for: 'iphone-and-ipad' (default, universal) or 'iphone' (iPhone only — the app still installs on iPads but runs there in iPhone compatibility mode, and App Store Connect no longer asks for iPad screenshots). This is the ONLY way to make the app iPhone-only: it is an Xcode build setting, so a UIDeviceFamily key in static/__dev/native/ios-info.plist is overwritten at build and does nothing. One-way door: App Store Connect rejects an update that drops iPad once a version supporting iPad has been released on the App Store, and the build then fails at upload. Before setting 'iphone', ask the user whether the app is already live on the App Store; if it is, tell them it cannot be made iPhone-only and do not set it. Takes effect at the next iOS publish.

upload_asset
Upload Asset
Upload a binary asset (image, font, audio, …) to the project's hosted storage. This uploads bytes you actually hold — a file you generated, downloaded, or read yourself. Chat attachments don't qualify: the user's attachments never reach MCP servers (you see attached images through vision only; there is no file, id, or URL behind them you can read), so for those use request_user_upload instead and the user re-picks the file in a card that uploads from their browser. Three modes. ChatGPT conversation files — a generated image, a file ChatGPT itself holds: pass the file as the `file` parameter and the host attaches a download link itself; this server fetches the bytes directly, at full quality (nothing goes through your sandbox or through base64 in arguments; content_type and size_bytes are optional here). Never downscale or re-encode a generated image to fit the inline cap — pass it as `file` instead. Files up to 3 MB you hold yourself — pass content_base64 plus size_bytes (the decoded byte count) and the upload completes in this call, returning publicUrl. Larger files — pass size_bytes alone to get an uploadUrl; PUT the raw bytes to it with the same content_type and exact byte count (e.g. `curl -X PUT -H 'Content-Type: image/png' --data-binary @file.png '<uploadUrl>'`), then reference publicUrl. Some sandboxes (claude.ai Cowork, ChatGPT containers) block egress to S3: if the PUT fails in any way — connection failure, proxy error, or a response without an x-amz-request-id header — that block is permanent for the session, so switch paths instead of retrying or re-encoding smaller: the `file` parameter in ChatGPT for any file that exists in this conversation, content_base64 for files under 3 MB, request_user_upload for user-provided files, or a PUT from inside the project VM via run_code_in_vm (re-mint the URL first; it is short-lived). For AI imagery generated fresh, use generate_image. A single file can be at most 100 MB via the presigned mode (the inline content_base64 mode is capped at 3 MB).
