Nothing serious here today

Today is the operative word: we check Tracea every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 15

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

payment
check_payment_allowed
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 }.
get_payment_whitelist
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.
payment_incoming
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.
payment_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.
payment_status
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.
agent
get_agent_actions
List all on-chain action IDs logged for a given agent on Tracea.
get_agent_info
Get the raw Tracea registry record for an agent: owner, permission scope, financial cap, active status, timestamps.
is_agent_revoked
Check whether an agent's mandate has been revoked on Tracea (immediate, scheduled or partial revocation).
action
get_action
Read a single logged agent action from the Tracea ActionLog contract by its numeric ID. Returns agent, action type, payload and timestamp.
identity
get_my_identity
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.
log
log_action
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.
owner
get_owner_agents
List all agent addresses registered on Tracea by a given owner address.
registration
get_registration_file
Fetch the ERC-8004 compatible registration file for a Tracea-registered agent, including the KYA legal principal block.
report
report_activity
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.
verify
verify_agent
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.

Tracea — questions

Answers built from our own checks of this server.

What can Tracea do?
It exposes 15 tools, read directly from the server on our last check. Among them: check_payment_allowed, get_action, get_agent_actions, get_agent_info, get_my_identity, get_owner_agents and 9 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is Tracea mostly used for?
Its tools cluster around payment and agent. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Tracea working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 255 ms. The bar chart above shows every period we have measured.
How do I connect Tracea?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Tracea need an API key?
No. Tracea completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 15 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Tracea?
It answers our handshake in 255 ms on average, which is faster than 57% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
