Tracea — legal identity (Know Your Agent) for AI agents, on-chain. ERC-8004 compatible.
Scored across 23 tools
Most tools target clearly distinct resources and actions, especially the payment, logging, and demarche sub-flows. Minor overlap exists between get_agent_info and verify_agent (both return registration/permission details) and between report_activity and log_action (both record actions), but descriptions explain the difference well enough for an agent to choose correctly.
All names use snake_case, which is a consistent baseline, but verb and prefix conventions vary: get_/is_/check_/log_/report_/verify_ mix with noun-first payment_* tools and the tracea_* demarche family. This is readable but noticeably mixed, so it earns a middle score.
23 tools is on the heavy side and spans several distinct domains: agent identity/KYA, x402 payments, action logging, and French administrative procedures. Each sub-domain has legitimate tools, but the total surface is borderline for comfortable agent selection.
The server covers core lifecycles well: identity lookup and verification, payment request/verification/status, on- and off-chain action logging, and a full demarche workflow from listing schemas to anchoring proofs and signature deposition. Minor gaps remain, such as no explicit agent revocation tool and no payment dispute/refund path, but these are not blocking for the main stated purposes.
Dry-run a payment BEFORE executing it: checks on-chain whether the agent's smart account would allow it (permission granted, within financial cap, destination approved if a whitelist exists). Returns { allowed, reason }.
Inputs: amount_eth (required), destination (required), agent_address (required).
Read a single logged agent action from the Tracea ActionLog contract by its numeric ID. Returns agent, action type, payload and timestamp.
Inputs: action_id (required).
List all on-chain action IDs logged for a given agent on Tracea.
Inputs: agent_address (required).
Get the raw Tracea registry record for an agent: owner, permission scope, financial cap, active status, timestamps.
Inputs: agent_address (required).
Get this agent's full Tracea identity (activity apiKey +, for v2 agents, its EOA private key and ERC-4337 smart account address) using a one-time activation code from the owner. The private key is returned ONLY ONCE — save it securely.
Inputs: agent_address (required), activation_code.
List all agent addresses registered on Tracea by a given owner address.
Inputs: owner_address (required).
Get the list of owner-approved payment destination addresses for an agent (anti-injection guardrail). Non-empty list = the agent's smart account can ONLY pay these addresses. Empty = all allowed.
Inputs: agent_address (required).
Fetch the ERC-8004 compatible registration file for a Tracea-registered agent, including the KYA legal principal block.
Inputs: agent_address (required).
Get the public URL of an agent's Tracea KYA verification card — the shareable page that presents the mandant entity, the permission scope, the financial cap and a proof hash, with a bilingual FR/EN transparency statement. Use it to hand a verifier a link. Returns the ready-to-share link plus the machine-readable JSON endpoints. Defaults to the 'standard' disclosure level, which is what the API exposes publicly.
Inputs: agent_address (required), lang, niveau.
Check whether an agent's mandate has been revoked on Tracea (immediate, scheduled or partial revocation).
Inputs: agent_address (required).
Log an agent action on-chain via Tracea (immutable audit trail, court-ready). Requires TRACEA_API_KEY env var. The action is signed by the account's wallet.
Inputs: action_type (required), agent_address (required), data.
Verify a x402 payment ON-CHAIN (the USDC transfer to your address, exact amount) and mark the session fulfilled. The blockchain is the ONLY source of truth — the payment_sessions table is never trusted alone. Returns { status: 'fulfilled', resource } if verified, or an error if not yet paid/expired.
Inputs: tx_hash (required), payment_id (required).
Create a x402 payment request (HTTP 402) for a resource you sell to another agent. Returns a paymentId, the USDC amount in units, the destination address and the TraceaPayments contract to call. The paying agent must then call TraceaPayments.payX402(destination, amount, paymentId) on-chain — the contract enforces financial cap + whitelist on-chain. Deliver the resource only after payment_incoming confirms fulfilment.
Inputs: amount_usdc (required), destination (required), agent, resource, +1 more.
Get the status of a x402 payment session (pending | paid | fulfilled | expired), with destination, amount and tx hash. Useful to poll while waiting for the paying agent's on-chain transaction.
Inputs: payment_id (required).
Report an action the agent just performed to its owner's Tracea activity feed (off-chain, free, instant). Call this AFTER every significant action (email sent, message posted, file modified, payment, purchase, booking...). Auth via the Tracea MCP URL (?key=...) from the agent's identity page, OR self-activate with a one-time activation code (?code=... or x-activation-code header) — the tool then receives its apiKey automatically.
Inputs: summary (required), category (required), agent_address (required), details, +2 more.
Seal a validated file as an immutable on-chain proof (Tracea Online, Base). Call this ONLY after tracea_check_demarche returned ok:true — it re-checks everything before anchoring. Requires the caller to be an authorized harness. Returns the proof fingerprint and the record hash.
Inputs: id (required), agent (required), donnees (required).
THE anti-rejection check. Submit the data you collected; it validates every field against the official procedure schema AND cross-checks critical values against official French registries (e.g. SIRET against INSEE Sirene). Returns { ok: true, recordHash } or { ok: false, errors: [{ field, message }] }. ALWAYS call this BEFORE telling the user the file is ready, and fix the exact fields reported.
Inputs: id (required), donnees (required).
Prepare le document officiel d'une demarche (CERFA ou demarche libre) et le rend signable. Appelle le generateur du backend Tracea, enregistre le dossier pour l'agent du visiteur et renvoie la reference + le chemin du PDF. A appeler APRES tracea_check_demarche (ok:true) et AVANT tracea_signature. Si des champs manquent, renvoie ok:false + champsManquants : ne fabrique jamais un document partiel.
Inputs: id (required), agent (required), donnees (required).
Verify an existing proof: was this file really anchored, when, by which operator, and under which rule version? Use the recordHash returned by tracea_check_demarche / tracea_anchor_demarche. Read-only and free.
Inputs: hash (required).
Return exactly which fields a given administrative procedure requires (name, type, required, format/pattern, bounds, example). Call this after tracea_list_demarches so you ask the user ONLY for the real fields, in the right format. Prevents hallucinated fields.
Inputs: id (required).
List the administrative procedures Tracea supports. ALWAYS call this first: it returns the exact procedure IDs so the AI never has to guess which form (CERFA) applies. schemaPret: true means guided mode (anti-rejection check available) is ready for that procedure.
Inputs: no named parameters.
DEPOSE REELLEMENT le document prepare dans Tracea Sign : cree les signataires, place la zone de signature, produit un lien de signature par personne et envoie les invitations. Exige pdfPath et signataires. Sans eux, aucun lien n'est renvoye.
Inputs: id, box, titre, niveau, +3 more.
Verify an AI agent's on-chain legal identity on Tracea (Base Sepolia). Returns registration status, financial cap, permission scope, revocation status, and KYA legal identity (mandant) when available. Use this BEFORE trusting or delegating work to an agent.
Inputs: agent_address (required).
