Tracea is an MCP server with 15 tools an agent can call, among them check_payment_allowed, get_action, get_agent_actions. It answers at https://mcp.tracea.online/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Tracea — legal identity (Know Your Agent) for AI agents, on-chain. ERC-8004 compatible.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 }. Inputs: agent_address, destination, amount_eth |
get_action | 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 |
get_agent_actions | List all on-chain action IDs logged for a given agent on Tracea. Inputs: agent_address |
get_agent_info | Get the raw Tracea registry record for an agent: owner, permission scope, financial cap, active status, timestamps. Inputs: agent_address |
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. Inputs: agent_address, activation_code |
get_owner_agents | List all agent addresses registered on Tracea by a given owner address. Inputs: owner_address |
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. Inputs: agent_address |
get_registration_file | Fetch the ERC-8004 compatible registration file for a Tracea-registered agent, including the KYA legal principal block. Inputs: agent_address |
is_agent_revoked | Check whether an agent's mandate has been revoked on Tracea (immediate, scheduled or partial revocation). Inputs: agent_address |
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. Inputs: agent_address, action_type, data |
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', Inputs: payment_id, tx_hash |
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 TraceaPayment Inputs: destination, amount_usdc, resource, agent, ttl_seconds |
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. Inputs: payment_id |
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 Trac Inputs: agent_address, category, summary, permission_label, in_permission, details |
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 Inputs: agent_address |

It answered our last check on 18 October 2026 in 136 ms. Over 10 checks since 5 September 2026 it answered 10. Status here comes from Neuronto's own probes, not from the publisher.
15, as returned by the server's own tools/list on 31 August 2026: check_payment_allowed, get_action, get_agent_actions, get_agent_info, get_my_identity, get_owner_agents, get_payment_whitelist, get_registration_file, and 7 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.tracea.online/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
