Qué hace este MCP

Discovers catalogued paid services, quotes and executes calls, and manages spend-capped crypto-backed payment delegations.

get_budget
Get spending budget
Read the spending budget pay_service spends from: its cap, what has been spent, what remains, how many payments were made (and the limit, if any), and when it expires. Reading costs nothing and charges nothing. Use it whenever the human asks how much is left, or before a run of paid calls. Money is in CENTS: `capCents` is whole cents; `spentCents` and `remainingCents` can carry up to four decimals because the budget is charged per call at 1/10,000 of a cent (e.g. `"1.632"` = 1.632¢), and `spentCents + remainingCents = capCents` while the budget is within its cap. Tell the human `message` as it stands and never substitute a figure of your own: the budget includes routing fees and rounding, so adding up your calls will not match it. With no `delegationId` it reads the budget pay_service would use; that only includes budgets that can still pay, so `{"status":"no_active_delegation"}` also covers a budget that ran out or expired — pass the `delegationId` from an earlier pay_service result to read that one anyway. Requires your Nevermined API key on the Authorization header.

Omit it to read the budget pay_service spends by default.'}}, 'additionalProperties': False}
get_payment_result
Get payment result
Read the result of a paid call, by its `paymentId`. Use it when `pay_service` answered `{"status":"pending"}` (the service was still working when the Router stopped waiting — the payment is made and the call keeps running), or to recover a result whose response you lost. Reading costs nothing and charges nothing. `state: "Pending"` — still running, call again in a few seconds. `state: "Ready"` — `status` is the service's HTTP status and `body` its response (`bodyEncoding` says whether it is parsed JSON, text, or base64). `state: "Failed"` — the call ended without a response; `failureReason` says why. `{"status":"not_available"}` — nothing to return: results are kept for 24 hours for the account that paid, and only then. Do NOT call pay_service again to get a pending result: that returns the same pending answer. Requires your Nevermined API key on the Authorization header.

get_service
Get a service
Fetch one catalog service by slug with metadata and a `requestShape` block. Read the endpoint's `payServiceArgs` before `pay_service`, replacing every `pathParams` placeholder. A checked invoke contract may include `invokePath`, `requestExample`, merchant-authored `responseSchema`/`responseExample`, and `exampleEvidence`: `paid-run` records a paid response, `challenge` proves only the request shape, and `docs` is unverified provider documentation. Only `paid-run` and `challenge` examples are pre-filled into `payServiceArgs`; adopt a `docs` example deliberately. Merchant response shapes are sanitised, and harvested examples are published only when they validate against their schema. An `endpointCheck` records a dated unpaid failure. A `requestSchema` is the merchant-declared JSON Schema of its request and is sanitised, not verified. A quote excludes the Router fee, which the budget must also cover. An unknown slug returns an error. Discovery only; no payment. Call `quote_service` for the live fee-inclusive total before paying.

list_categories
List service categories
List the categories of paid services in the Nevermined Agent Services Catalog, with a count per category. Discovery only; no payment.

{'type': 'object', 'properties': {}}
list_payments
List payments
List your Router payments: the unified ledger across every service and delegation, newest first, at most 1000 records. Each record carries its `id` (the `paymentId` get_payment_result takes), `createdAt`, `status`, `protocol`, `network`, `requestId`, `delegationId` and `amount` in the asset's smallest unit (see `assetDecimals`), not in cents. Each row also carries `deliveryStatus`: `delivered` (request settled), `charged_not_delivered` (request failed and the merchant charge was observed), `charged_unconfirmed` (charge observed; delivery unconfirmed), `not_charged` (reconciliation proved no merchant charge), or `pending` (charge outcome unknown). On SPT and card rails, `pending` is not proof of no charge; flag `charged_not_delivered` to the user. Use this tool to reconcile an uncertain payment or find a paymentId; it does not return service responses (use get_payment_result) or the remaining budget (use get_budget, whose figures include fees and rounding). Reading costs nothing. Requires your Nevermined API key on the Authorization header.

payment_summary
Payment summary
Count your Router payment requests: `total` is how many there were in the period (uncapped, unlike list_payments) and `series` is that count per day (`date`, `value`), oldest first. `chargedNotDelivered` is the count of failed payments in the period whose merchant charge was observed; flag a non-zero count to the user. This reports numbers of payments, not money: for what has been spent or what is left use get_budget, and for amounts per payment use list_payments. Reading costs nothing. Requires your Nevermined API key on the Authorization header.

pay_service
Pay for and call a service
Pay for a catalog service from your spend-capped delegation and return the vendor response. This charges real funds. Call `get_service` FIRST: its `requestShape.endpoints[]` lists the callable paths with their HTTP method and price, and each `payServiceArgs` is the `slug`/`path`/`method` to pass here, after replacing any `pathParams` placeholder in `path` with a real value. A bare slug reaches the service base URL, which for a multi-endpoint API answers 404 instead of a payment challenge; only a single-endpoint service is called by slug alone. Send the endpoint's `payServiceArgs`: they carry an example only when it is `paid-run` or `challenge`. A `docs` example (and its `invokePath`) is unverified — use it only deliberately, filling any path parameter with the entity you want; otherwise build `body` from the endpoint description or the provider's docs. `method` may be omitted: it is taken from the catalog endpoint matching `path` (POST when the catalog names none) and echoed back under `request`. To accept a live quote, pass its `quoteId` before `expiresAt` with the exact same call arguments; the Router uses that cached challenge and exact fee-inclusive total. Keep `maxTotalCents` as an independent ceiling. Repeating an identical call (same arguments, no `fresh`) charges nothing new: on a deployment running API 1.48 or later it is answered within 24 hours from the first call's stored result, or its `pending` answer; on an older deployment it comes back as `already_paid`. For an ASYNC service, where you submit once and then poll a status endpoint with the same id, set `fresh: true` on every poll INCLUDING THE FIRST: otherwise each later poll reuses the first poll's idempotency key and gets the first poll's stored answer (or `already_paid`) back, so the status never advances. `fresh` makes each poll a distinct, separately billed call (the merchant charges per status call). Leave `fresh` off the submit and off any retry of a call whose outcome is unsure, because with `fresh` a retry is not de-duplicated and is charged again. A completed call returns `paid`, `upstreamStatus` (the vendor's HTTP status) and `response` (its body); `paid: true` with a non-2xx `upstreamStatus` may still have cost the merchant price. Outcomes to act on: `{"status":"pending"}` means the payment was made and the service is still working; call `get_payment_result` with its `paymentId` every few seconds instead of calling pay_service again. `{"status":"already_paid"}` means this call's idempotency key already carries a payment whose result is not replayed here (the original call failed, its 24-hour result expired, the `requestId` was reused for a different request, or the deployment predates result replay, API 1.48); nothing new was charged, and it does not by itself say whether the original succeeded. Read the original with `get_payment_result` (`paymentId`) or `list_payments`. A new `requestId` starts a separate, separately charged purchase: use one only after that read shows the original failed and the human still wants the result. `{"error":"payment_indeterminate"}` means the charge may or may not have landed: check `list_payments` first, and to retry reuse the returned `requestId` verbatim without `fresh` so the retry stays idempotent. `{"error":"per_call_max_exceeded"}` means no charge; raise `maxTotalCents` only after a deliberate decision and retry with the same requestId. `quote_not_found`, `quote_expired`, and `quote_mismatch` are named no-charge quote refusals; quote again rather than paying unpinned. `{"error":"payment_failed"}` is a definite decline (see `code`, `message` and `retryable`). These charge nothing: `{"payable":false}` (not payable via the Router; no upstream URL is ever returned), `service_not_found` (wrong slug), `catalog_unavailable` and `delegation_lookup_failed` (transient; retry later), `no_delegation` (call `setup_delegation`), `router_controls_unavailable` (the API behind this server is too old to enforce `search`, `quoteId` or `maxTotalCents`; tell the human instead of retrying without them) and `credential_refused` (re-authorize). A paid result also carries `delegationId` and `budget`, the spending budget after this call (`capCents`/`spentCents`/`remainingCents`, cents with up to four decimals), so to say what has been spent or what is left, repeat `budget` rather than adding up your calls yourself; `budget: null` means it could not be read this time, not that it is zero (call `get_budget`). Requires your Nevermined API key on the Authorization header.

quote_service
Quote a service call
Price ONE call to a catalog service WITHOUT paying it: it charges nothing, signs nothing and reserves no budget. Pass exactly what you would pass to `pay_service` (the same `slug`, `path`, `method`, `search`, `headers`, `body` and `delegationId`): the Router sends that request to the service unpaid, reads the price it asks for, and returns an opaque `quoteId`, its short `expiresAt`, the rail (`protocol`), the network and merchant amount (`settlement`) and the fee-inclusive total (`fee.capChargedCents`, whole cents rounded up; `fee.capChargedMicros` exact, in 1/10,000 of a cent). Unlike the `quote` on a get_service endpoint (the last merchant price the catalog observed, routing fee excluded), this is priced live for your exact request and includes the fee. Because the request really reaches the service, a service that does not charge for it performs it, so take care quoting a method with side effects; and a quote spends the same per-service rate limit as a payment, so quote once per decision rather than polling. It prices the delegation pay_service would charge (`optionSet: "delegation"`, naming its `delegationId`), or, with no delegation set up, what a personal crypto delegation would select (`optionSet: "deployment"`); in that case `nextTool` is `setup_delegation`: set one up and quote again before paying, since the delegation you create can select a different rail and price. It checks neither your remaining budget nor your wallet balance (see get_budget and wallet_balance). Next step (`nextTool: "pay_service"`): if `fee.capChargedCents` fits what you planned to spend, call `pay_service` before expiry with the same arguments, the quoted `delegationId`, `quoteId`, and `maxTotalCents` set to that figure as a number. The quote id fixes the exact challenge and fee-inclusive total while `maxTotalCents` remains an independent ceiling. `paymentRequired: false` means the service did not ask for payment for this request; `upstreamStatus` is its answer, and a non-2xx usually means the path, method or body is wrong. The service response itself is never returned. Outcomes, all charging nothing: `{"payable":false}`, `service_not_found`, `catalog_unavailable` and `delegation_lookup_failed` as in pay_service; `quote_unavailable` (no quote can be made here and retrying will not change that, so bound the price with pay_service `maxTotalCents` instead); `quote_failed` (the Router refused to price the call, or did not answer; see `code`, `message` and `retryable`); `credential_refused` (re-authorize).

route_by_intent
Find (and optionally pay) the best service for a need
Given a plain-language description of what you need, find, and optionally pay in the same call, the single best payable catalog service, so you do not have to pick among listings yourself. Use it instead of search_services when you want the right service for a task rather than a list to browse: it ranks candidates on Nevermined's own relevance and quality signals (deterministic; no model reads the merchant listings), applies a fail-closed payability gate (listed, healthy, moderated, x402/mpp, not flagged unpayable), and returns the winner as `chosen` (with its opaque invoke handle, never a raw host) plus a ranked `shortlist`; every shortlist item carries a closed `matchReason`, `gateReason`, per-item `rankingSource`, and one scale-specific score. With `autoPay:false` (the default) it returns the pick only and charges nothing; the next step is normally `get_service` on `chosen.slug`, then `pay_service` with the endpoint you need. With `autoPay:true` it also pays the winner through the same path as pay_service and returns the upstream call in `result`: `result.status` and `result.body` are the vendor's answer, and `result.paid: true` means a payment was attempted, not that it settled, so read `result.payment.status` (`Settled`, `Issued` or `Failed`). autoPay calls the winner at its base URL plus any `path` you pass, and you only learn the winner from this call, so it suits single-endpoint services; a multi-endpoint winner typically answers 404 at its base URL. autoPay requires `requestId`; an API-key caller must also pass `delegationId`, while an OAuth-connected caller spends from the grant it approved and needs none. Outcomes: no listed, payable match → `{"status":"no_fundable_match"}` (broaden the intent or filters; nothing charged), never a wrong pick; `missing_autopay_fields` (nothing charged); on autoPay, `payment_indeterminate` (check `list_payments`, and retry only with the same `requestId`) and `already_paid` (this `requestId` was already paid, see `paymentId`; nothing new billed). Every pick and each of these outcomes carries an `instructions` string with the next step; a payment the Router declines on autoPay comes back as a tool error carrying the API's message. Requires your Nevermined API key on the Authorization header.

search_services
Search services
Search the Nevermined Agent Services Catalog for paid services, ranked by ARD HYBRID relevance — semantic (meaning) matches merged with lexical (keyword) matches, most relevant first — falling back to pure lexical when the embedding provider is unavailable. Each result includes a closed matchReason, a per-item rankingSource, and one scale-specific score. A query is required; the other filters are optional. Returns matching listings (vendor, protocol, price label, endpoint). Only the first page is returned: the `pageToken` in the result cannot be passed back to this tool, so to see other matches narrow the query or filters, or raise `pageSize` (up to 100). Discovery only; no payment. To have the platform PICK (and optionally pay) the single best service for a need instead of choosing yourself, use route_by_intent.

setup_delegation
Set up a spending delegation
Start the spending-delegation ceremony and return ONE URL for a human to open. Use this when `pay_service` returns `{"error":"no_delegation"}` — it is the way out of that state. It sets up a stablecoin (crypto) delegation that spends from the human's personal wallet, so that wallet also needs funds on the network a service settles on (see `wallet_balance`); it does not enroll a card or create a card delegation. The human sets the currency, spending cap, duration and transaction limit themselves in the browser; you CANNOT set them and must not ask the human to pass them to you. Returns `{"status":"human_action_required","url":…}` — relay the url, wait for the human to confirm, then simply call `pay_service` again. `{"status":"already_active"}` means a usable spending budget is in place — for an OAuth commerce caller it is the grant approved on the consent screen — and nobody needs to do anything: tell the human `message` as it stands (it states the cap, spent, remaining and expiry the API reports, in a voice written to be relayed), then follow `instructions` and call pay_service. The url embeds a short-lived session token, so treat it as sensitive and give it only to the account owner. Other outcomes: `delegation_setup_unavailable` (this deployment cannot run the ceremony) and `delegation_setup_failed` (the session could not be started) produce no URL; `return_url_not_allowed` means drop or fix `returnUrl`; a `human_action_required` answer with `delegationCheck: "failed"` means an existing budget could not be ruled out, so follow its `instructions` and try pay_service first.

wallet_balance
Wallet balance
Read the balances of YOUR OWN PERSONAL wallet — the funding source the crypto rails PULL from when pay_service charges a PERSONAL delegation. It answers `how much do I have, and on which chain`. Reading costs nothing and charges nothing. WHAT IT DOES NOT COVER, so you do not mis-diagnose: a delegation backed by an ORGANIZATION wallet is paid from that wallet, not this one; and a CARD delegation has no wallet at all — there `BCK.ROUTER.0009` is the card ISSUER declining, with nothing to top up, so this tool does not apply and the answer is a different card. BY RAIL: on MPP the wallet is checked BEFORE anything is signed, and the `BCK.ROUTER.0009` you get back already names the wallet and the chain — what it never says is HOW MUCH is there, which is what this tool supplies. On x402 there is NO balance pre-check and `BCK.ROUTER.0009` is never raised: the credential is minted, budget is reserved, and a short wallet only surfaces when the merchant's on-chain transfer fails — by which point your budget is already committed, and the reserve comes back only once the reconciler has seen the authorization expire unconsumed. So on that rail read the balance BEFORE you pay, not after. By default this reports EVERY network this deployment settles on, and you must read the one the merchant quoted: a healthy balance on one chain says NOTHING about the other, and most services settle on only one of them. Pass `network` (a chain id) to read a single chain. A token whose `atomic`/`formatted` is `null` was NOT READ (the on-chain read failed) — that is not a zero balance, and reporting it as empty is wrong; a chain that could not be read at all comes back as an entry with `error` instead of `balances`. This tool diagnoses and fixes nothing: there is no on-ramp and you cannot top your own wallet up, so a genuine shortfall is a stop condition — report the network and the amount to your human, and do not retry the payment.
