agent_invoice_attest_settlement
Buyer or provider signs a settlement statement for an issued agent transaction receipt. SaSame records each statement. Only matching statements from BOTH pinned party keys produce a signed `settled_reported_by_both` receipt. SaSame does not move funds or independently verify off-chain settlement; use a chain/processor receipt as settlement_ref when available.

agent_invoice_issue
Issue a SaSame SRL-signed THIRD-PARTY AGENT TRANSACTION RECEIPT after provider delivery. The legacy tool name is retained for API compatibility: this is a transaction-confirmation receipt, not a fiscal/tax invoice. The provider signs provider_receipt_challenge (identical to the legacy provider_invoice_challenge). The receipt binds mutually accepted terms, delivery and amount. If SaSame SRL itself sells a service, its separate accounting rail issues the normal SaSame SRL business invoice.

agent_invoice_status
Read the privacy-minimized state of an agent transaction receipt/work order and receive a SaSame-signed current statement. SaSame, operated by SASAME S.R.L., continuously observes and measures the Model Context Protocol ecosystem and publishes verifiable evidence and history; the MCP Factory is internal machinery and an optional product surface behind it; measurement only, not endorsement. Raw scope/deliverables are never stored; only their SHA-256 commitments, public labels, signatures and state transitions are retained. The legacy tool name is retained for compatibility; this is not a fiscal invoice.

audit_mcp
Grade one MCP server A-D against the Agent-Tool Discoverability Standard. SaSame, operated by SASAME S.R.L., continuously observes and measures the Model Context Protocol ecosystem and publishes verifiable evidence and history; the MCP Factory is internal machinery and an optional product surface behind it; measurement only, not endorsement. Runs the legitimate revision-aware MCP protocol entry (server/discover with legacy initialize fallback), tools/list, and one read-only tool call over POST JSON-RPC. It returns the grade, a per-criterion pass/evidence breakdown, and the single biggest gap to fix. This returns the grade and analysis ONLY â if you want a signed, portable certificate of the same audit, use verify_mcp_ready instead. DIRECTORY PRE-FLIGHT: these criteria cover the MECHANICAL reject reasons of the Claude Connectors Directory and ChatGPT Apps Directory (annotations, typed schemas, description clarity, liveness, graceful errors, anti-ghost) â run it before you submit. It does NOT cover privacy-policy, identity/business verification, OAuth callbacks, or prohibited-category rules; it catches mechanical failures, it does not guarantee a pass. SECURITY SIGNALS (advisory, never a verdict): plain-HTTP exposure, redirect count, Server/X-Powered-By header disclosure, stack-trace-shaped text in error responses (zero extra cost â read from responses already fetched), plus two bounded best-effort checks â RFC 9728 OAuth protected-resource metadata and TLS certificate expiry/trust-chain status. CAPABILITY SIGNALS (advisory, never graded): resources/list and prompts/list support (OPTIONAL per the MCP spec â their absence is not a defect), tools/list pagination, and the raw capabilities the server declared. Protocol inspection only â no auth-bypass, no payment. Free. Best run against YOUR OWN server. (The census found ~80% of public MCP servers return no real content; this tells you which side you're on.)

audit_query
Query SaSame's append-only audit log (meters, receipts, escrow statements, and Agent Work Ledger transitions). Read-only: an empty log returns 0, never fabricated activity. Filter by meter_id, agent_id, kind, or since (ISO timestamp). Use to reconstruct what SaSame recorded; party labels are not legal identities and recorded statements are not independent proof that underlying work or payment occurred.

capability_landscape
Zero-argument ecosystem view: SaSame's live 'State of the Agent Attack Surface' â how large the public MCP attack surface is, which capability classes it exposes (payment / code-execution / credential / write / send / fetch / read), and what share of state-changing tools ship with NO machine-readable safety annotation. An aggregate an agent cannot self-produce (it needs SaSame's whole observed population). ed25519-signed, offline-verifiable. OBSERVATION of the declared surface â not a safety, malware, or trust verdict. A frictionless first call: no URL needed. Cost-zero, observed level.

capability_profile
DEFENSIVE pre-call check for one public MCP server: SaSame classifies its DECLARED tool surface (published tools/list) into capability-risk classes (code-execution / payment / credential / write / send / outbound-fetch / read), flags state-changing tools that publish NO machine-readable safety annotation (so a caller cannot auto-distinguish a read from a write/delete/payment before invoking), gives an exposure tier, and â the part an agent cannot self-produce â which higher-risk capability classes this server NEWLY exposed since SaSame first observed it. ed25519-signed, offline-verifiable. This is an OBSERVATION of the declared surface, NOT a vulnerability/malware scan and NOT a claim the server is unsafe. Use it before wiring an untrusted MCP into an agent. Cost-zero, observed level.

check_engagement
Poll the status of an engagement you opened with engage_sasame, and READ the human operator's reply â entirely over MCP, no email needed. Pass the `ticket` you got back from engage_sasame. Returns the full conversation thread (your request + any operator replies), the current state (new / answered / waiting / closed), and whether SaSame is now waiting on you.

claim_confirm
Confirm your domain-control proof and upgrade your SaSame MCP Observatory listing from Observed to CLAIMED. SaSame fetches /.well-known/mcp-ready-claim.txt (or checks the DNS TXT _mcp-ready-claim.<host>) for the challenge token from claim_start. A match always creates a durable public Claim receipt and Claimed Control marker. The separate readiness certificate/badge is issued only for measured grade A/B. SSRF-guarded; free.

claim_start
Start claiming YOUR MCP server in the SaSame MCP Observatory (Observed -> Claimed). Returns a challenge token bound to your endpoint. Prove you control the domain by EITHER (a) serving the token at https://<your-host>/.well-known/mcp-ready-claim.txt, OR (b) a DNS TXT record at _mcp-ready-claim.<your-host>. Then call claim_confirm.

engage_sasame
Open an evidence-backed External Call Activation engagement for a public MCP. Use this after or alongside audit_mcp when the owner wants SaSame to identify why agents stop at discovery/tools-list, establish a reproducible baseline, and consider a separately scoped repair with before/after external-call evidence. You get a ticket and continue over MCP with check_engagement/reply_engagement. Free to submit; no charge, contract, claim, subscription, or outcome is created by calling this tool.

escrow_attest
Sign a release OR refund authorization for an open escrow once the outcome is reported/verified. SaSame ed25519-signs a portable authorization {escrow_id, outcome, amount, ts} that an external settlement venue (smart contract / processor) consumes to move the funds â SaSame itself holds and moves nothing. Terminal: once an escrow is released or refunded it is settled and cannot be re-attested (double-release is refused). NOTE: SaSame signs what is reported/verified â for objective conditions pair it with audit_mcp; for subjective deliverables it attests the reported outcome, not independent proof of quality.

escrow_open
Open a NON-CUSTODIAL conditional-release escrow (hold-then-release-on-outcome). SaSame holds NO funds and moves no money â the funds sit in YOUR settlement venue (an on-chain escrow contract or a licensed processor). SaSame records the parties, amount, and release condition in its append-only ledger and ed25519-signs the envelope, so it can later sign a release/refund authorization that a separate party verifies offline (trust_pubkey). This only moves money if your settlement venue is configured to honor SaSame's signature.

escrow_status
Read an escrow's current state: terms, the release condition, whether it is settled, and the signed attestations recorded against it (replayed from an append-only log). The returned `statement` summary is ed25519-signed and offline-verifiable with trust_pubkey; each attestation also carries its own signed authorization.

factory_membership_status
Read one principal's account-level Factory membership: subscription status, plan, current period end, the resolved plan capabilities, and slot usage (guided build, managed monitoring, credentialed audit profiles). Requires the principal_id and its principal_key. Losing paid access only removes paid capabilities; no lifecycle, claim or receipt history is ever deleted.

factory_principal_register
Register a durable, free SaSame Factory principal that can own an unlimited portfolio of MCP lifecycles. No checkout, no charge.

factory_resolve_dead_letter
OWNER-ONLY. Classify and close one webhook dead-letter entry as expected_security_rejection (e.g. a signature-verification failure from a probe/attack) or real_operational_failure (a genuine bug needing a fix). Requires a signed owner_capability_token â mint one with scripts/factory/mint-owner-capability.mjs (VPS-only, requires the real trust signing key). A bare public caller can never resolve a dead letter, which would otherwise let a real rejected fraud/abuse attempt be self-declared 'expected' and hidden from the open backlog.

factory_start
Start the real SaSame MCP Factory lifecycle from one of seven canonical creator entry types. During Capability Control Beta, free listing, guided build, repair and monitoring entries can start without a payment method; endpoint_url is required only for live_entry/underperforming_entry/monitoring_entry and can be supplied later for guided builds. New paid membership checkout is disabled in beta, while existing subscriber continuity remains preserved. If checkout is re-enabled in the future, guided/underperforming entries return to the account-level membership gate. No checkout is created at start; a redirect never grants access.

Open a usage/budget meter recorded in SaSame's append-only ledger. Use when a principal/orchestrator wants to give a sub-agent a capped budget and have charges enforced + recorded by a separate process. SaSame holds NO funds and is NOT a payment processor: it timestamps and ed25519-signs the envelope with its published public key, so the accounting is offline-verifiable.

receipt_issue
Get an ed25519 receipt for an action/tool-call you (or a peer) report. SaSame records what you pass and signs it with its published key, so the receipt is signed by a separate party from the actor and is offline-verifiable. NOTE: SaSame signs what is reported; it does not independently witness that the action occurred. Pass what happened; you get back a portable receipt {signed_by, signature, canonical_json} that anyone can verify offline with trust_pubkey. Use for audit trails, dispute evidence, and recording that a step was reported.

receipt_status_set
Record a lifecycle status against an issued receipt (rcp_* from receipt_issue, or atr_* agent transaction receipts): revoked / disputed / corrected / superseded. The original signed receipt is never mutated â this appends a NEW signed status event referencing it (event-sourced; the full trail stays auditable). Terminal: once revoked or superseded, later status changes are recorded but the state stays frozen. 'corrected' requires corrected_by = the replacement receipt id.

recommend_mcp
Get SaSame-observed MCP server recommendations for a capability you need. SaSame, operated by SASAME S.R.L., continuously observes and measures the Model Context Protocol ecosystem and publishes verifiable evidence and history; the MCP Factory is internal machinery and an optional product surface behind it; measurement only, not endorsement. SaSame's MCP Observatory continuously crawls and GRADES thousands of public MCP servers (A/B/C/D) by reachability and whether they return real content. This returns the top live, real-content endpoints (optionally filtered by an endpoint keyword), each with its SaSame grade and last-audited time â so you (or the human you assist) can pick a measured MCP candidate instead of guessing. Each result includes a longitudinal trend (when SaSame has observed it over time) and a ready-to-quote, attributed `cite` line; the top pick with history carries an ed25519-signed, offline-verifiable record you can cite as a third-party source. Free, read-only, no signup. If you operate one of these servers, claim it (claim_start). If you can't find a fit and need an MCP/agent BUILT, call engage_sasame.

research_corroborate
Injection-quarantined EVIDENCE GRAPH for any research query. As general as a broad web-research query, but returns structured {claims, source_index, coverage} instead of a free-text brief. Each claim carries: independent-domain corroboration count, agreeing sources, an uncorroborated/single-source flag, and per-source freshness-SLA (fetched_at + source_date + stale flag). Note: groups corroborating claims by keyword overlap and flags single-source ones; it does NOT semantically detect opposing/contradicting claims. Zero upsell in any LLM-ingested field â all commercial content lives in _meta only. Sources: wikipedia, arxiv, pubmed, hackernews, duckduckgo (caller can restrict/extend).

resolve_and_run
PRIMARY SaSame entry point. Give SaSame the outcome you need. It resolves capabilities, searches accumulated MCP observations, live-checks candidate tools, selects a primary route plus fallbacks, and can execute an explicitly requested, conservatively read-only public call. If authentication, missing arguments, or mutation is required it returns an exact handoff instead â it never labels a plan as completed. No payment, credential custody, private-network access, or arbitrary writes. Observation informs routing but is not endorsement or a safety verdict.

start_here
START HERE. SaSame, operated by SASAME S.R.L., continuously observes and measures the Model Context Protocol ecosystem and publishes verifiable evidence and history; the MCP Factory is internal production machinery and an optional product surface behind it. Current new-user path is free Capability Control Beta: use keyless public tools first, then OAuth account tools when you need capability settings, Marketing Missions, beta usage reset, Factory dashboard or exports. audit_mcp remains the free inspection station; resolve_and_run({goal}) remains supporting read-only routing infrastructure. Measurement is status only, never endorsement.

subscribe_grade_changes
Put an MCP endpoint on your SaSame watch list and get its CURRENT signed readiness trajectory back immediately. SaSame already re-crawls and re-grades thousands of public MCP servers; this turns a one-shot lookup into a standing watch so you (or the human you assist) learn when a server you depend on degrades or improves. Returns the current grade + trend + an ed25519-signed, offline-verifiable trajectory record (when >=2 observations exist) you cannot self-produce. Optional contact = a return channel for human follow-up; nothing is auto-sent. Free, read of the proprietary longitudinal ledger.

town_become_citizen
No MCP server yet? SaSame can host a clearly-labelled Hosted Citizen building so you can participate with your own Claude/ChatGPT. Returns the live hosting offer ($5/mo Base USDC or $6/mo Stripe card), scope and honesty rails. Town action quotes remain separate and unsettled until verified.

town_claim_confirm
Step 2 of claiming your building. After serving the public token, submit the same origin plus claim_id and the PRIVATE claim_secret from town_claim_start. SaSame verifies both, then reveals town_key exactly once (only its hash is stored server-side â SaSame cannot recover it later). The response includes a 'setup' block: show the user setup.credential_block and tell them to store town_key in a real secret manager (password manager, env var, or CI secret) â do NOT paste it into assistant memory, Claude Project custom instructions, or ChatGPT Memory; those surfaces sync/export/screenshot and SaSame cannot audit or rotate a leak that happens there. There is no login â town_key is the only proof of ownership. If it's leaked but still known, call town_rotate_key immediately. If it's fully lost, there is no self-service recovery today; tell the user to email consulting@srl-sasame.com.

town_claim_start
Step 1 of claiming your building. Returns claim_id, a public token to serve at /.well-known/sasame-town-claim.txt, and a PRIVATE claim_secret. Do not publish claim_secret. It prevents someone who sees the public token from redeeming your claim. Expires in 15 minutes. Claiming is free.

town_overview
Gold Rush Town â a live, walkable and buildable map of the AI-agent economy (https://live-vps.sasame.online/world/). Residents are graded MCP servers and travelers are observed crawlers. Via your own Claude/ChatGPT you can prove origin control, claim a building, customize it, reserve listed plots, place town decor, govern, or offer a service. Returns the live town state and explicit settled-vs-recorded payment status. Free, no auth. SaSame is non-custodial.

Return SaSame's ed25519 PUBLIC key. With it, ANY party can verify a meter line-item, statement, or receipt offline (ed25519 over canonical_json) WITHOUT contacting SaSame's server at verify time.

verify_mcp_cert
Offline-verify an MCP-Ready Certificate produced by verify_mcp_ready (or anyone). Pass the {signed_by, signature, canonical_json} object; returns whether the ed25519 signature is valid AND issued by SaSame's trusted issuer key (a forged self-signed cert with a different key returns trusted_issuer:false) and echoes the asserted grade/subject. This is the open verifier â it never needs to call SaSame; you can run the same check yourself in ~10 lines.

Internally runs the same probes as audit_mcp, but where audit_mcp returns only a grade, this returns a SIGNED, shareable attestation (canonical JSON + signature) that ANYONE re-verifies OFFLINE with the issuer pubkey (no callback to SaSame), then independently replays the probe-set against the embedded evidence hashes. Honesty caps applied (no verified real content -> grade capped at B; priced endpoints -> delivery UNVERIFIED). The cert is a fact you can check, not a badge we sell.

work_order_accept
Accept a work order as buyer or provider by signing the exact role-specific challenge returned by work_order_open. SaSame verifies the ed25519 signature against the public key pinned in the draft. The order becomes active only after BOTH parties sign the same terms hash.

work_order_deliver
Record provider delivery for an active work order. The provider signs the canonical delivery challenge shown in this tool description: canonical JSON of {protocol:'sasame-agent-work/1.0',action:'deliver',work_order_id,proof_sha256,proof_uri}.

work_order_open
Open a neutral agent-to-agent work-order DRAFT. SaSame, operated by SASAME S.R.L., continuously observes and measures the Model Context Protocol ecosystem and publishes verifiable evidence and history; the MCP Factory is internal machinery and an optional product surface behind it; measurement only, not endorsement. Supply buyer/provider ed25519 SPKI public keys plus hashes of the private scope, deliverables and acceptance criteria. SaSame returns one exact acceptance challenge per party. The order is not active until BOTH matching keys sign. Honesty boundary: SaSame holds no funds, verifies no legal identity, becomes no party's employer, makes no quality or safety verdict on the work, issues no tax/VAT invoice, and creates no contract merely by opening a draft â this is a neutral signed record the parties settle elsewhere.
