Un programa comprueba el servidor una vez al día: initialize y tools/list, sin modelo. Los tokens son la longitud de las definiciones, a unos cuatro caracteres por token. La nota promedia seis comprobaciones del nombre, la descripción, el esquema y las anotaciones de cada herramienta; dice lo bien descritas que están, no si funcionan. La nota pondera solo lo medido: si responde (25%), si hace el trabajo del producto (25%), definiciones (20%), contexto (10%), uso (10%) y lo fácil que es conectarse (10%). Lo que no se midió queda fuera, y una instrucción oculta limita la nota a 40. El estado de los servidores MCP de los proveedores: método y números →

• get-protocol-summary

  Get a concise explanation of what Crinkl is and how the protocol works. Use this first if you have no prior context about Crinkl. Returns a plain-text overview of the verification pipeline, token types, and settlement model.

• get-cumulative-gmv

  Get cumulative Gross Merchandise Value (GMV) from the public cumulative feed. The live Crinkl site displays this live beta cumulative total on top of the finalized alpha base; provide startDate to bound the window explicitly. Returns a…

• get-daily-gmv

  Get the signed GMV summary for a specific calendar date (UTC). Returns the verified spend count, total USD cents, and a cryptographic signature from the Crinkl authority. Each daily GMV token is independently verifiable using the issuer's…

• get-trailing-gmv

  Get a rolling N-day GMV trend summary. Returns daily verified GMV figures for the trailing window, enabling trend analysis of verified commerce volume. Each day's figure is backed by individually signed spend attestation tokens.

• get-spend-signals

  Get recent verified spend activity signals from the Crinkl network. Each signal represents a cryptographically attested receipt that has passed OCR extraction, store resolution, and hard verification. Signals include store name, category…

• resolve-cbsa

  Resolve a CBSA (Core Based Statistical Area) code to its metro area name. CBSA codes appear in spend signals and distribution data as 5-digit codes (e.g. '35620'). This tool converts them to human-readable names (e.g. '35620' → 'New…

• get-merchant-summary

  Get aggregated merchant and category distribution across all verified spends. Shows top store brands, category breakdown (grocery, restaurant, gas, etc.), and spend concentration metrics. All data is derived from cryptographically…

• get-spend-distribution

  Get the geographic and category distribution of verified spends over a trailing window. Returns a breakdown by store category and CBSA (Core Based Statistical Area) metro code, enabling analysis of where and how verified commerce is…

• get-settlement-summary

  Get reward settlement statistics for supported reward rails. Returns the current BTC price used for reward calculations, sats-per-receipt rate, reported Lightning Network payouts, total sats claimed by users, and wallets with balance…

• get-gmv-inclusion-proof

  Get a Merkle inclusion proof that a specific spend is included in a daily GMV total. Returns the spend leaf hash, sibling hashes for the Merkle path, and the GMV root hash. This cryptographic proof allows anyone to independently verify…

• verify-reward-commitment

  Verify a reward commitment token's cryptographic integrity. Checks that the reward Merkle tree is valid, the batch signature is authentic, and the reward amounts match the committed values. Reward commitments bind point/sat allocations to…

• verify-issued-gmv

  Verify a supplied spend/GMV artifact bundle. Accepts a spend attestation token, GMV token, GMV inclusion proof, and reward commitment token, then verifies: (1) spend token signature is valid, (2) GMV token signature is valid, (3) spend is…

• get-recent-issued-proofs

  Get recent gateway-issued artifact bundles for portable spend/GMV verification. Bundles can include a spend attestation token, GMV inclusion proof, reward commitment token, and optional batch anchor. These artifacts support independent…

• get-issuer-keys

  Get the Crinkl authority's Ed25519 public key used to sign all attestation tokens. This key can be used to independently verify the signature on any spend attestation token, GMV token, or distribution token issued by the Crinkl protocol…

• get-reward-policy

  Get the current Crinkl reward policy. Returns the active policy version, SHA-256 policy hash, reward parameters (referral bonuses, base points), category multipliers (grocery 1.5×, dining 1.5×, etc.), $CRINKL token holding tier…

• get-agent-capabilities

  Get Crinkl's canonical external agent capability catalog. Returns live authority levels, delegated capabilities, human-only governance controls, approval boundaries, delegation model, and each gateway/MCP capability with route, tool name…

• get-vendors

  Get the currently approved DKIM vendor domains exposed by the public agent endpoint. Standalone agents use this list to seed Gmail searches; unknown vendors are queued for review when submitted. No authentication required.

• pair-agent

  Start the human-authorized agent pairing flow. Generates a 4-character code that a human approves in the Crinkl PWA to authorize the agent. Returns the code and expiration time (10 minutes). No authentication required.

• claim-api-key

  Poll for the API key after the human approves the pairing code in the Crinkl PWA. Returns 202 while pending, 200 with the API key once approved, 410 if expired. Poll every 5 seconds. No authentication required.

• verify-receipt

  Preview DKIM verification of a billing email without creating a spend or earning sats. Returns extracted invoice data (vendor, amount, date, DKIM status). The full email is required because DKIM signatures are computed over the original…

• submit-receipt

  Submit a DKIM-verified billing email to mint a spend token and earn sats. The full email is required because DKIM signatures are computed over the original RFC 2822 message bytes. After verification, only vendor, date, total, and currency…

• get-agent-me

  Get your agent's submission count, earned sats, and wallet-level stats. Shows both per-API-key numbers (your submissions) and wallet-wide numbers (all sources including the human's manual scans). Returns satsPerReceipt (current rate).
