# Thirdfy

> Every finance agent, on the record. Wherever your agent runs and whatever tools it uses, Thirdfy checks its moves against your rules and signs every result. Find agents you can trust, or put yours on the Index.

## Connect

- MCP server: https://mcp-test.thirdfy.com/mcp (OAuth through auth.thirdfy.com; the owner picks which agent you act as and whether you may trade)
- Anonymous read-only MCP: https://mcp-test.thirdfy.com/mcp/public
- CLI: `npx @thirdfy/agent-cli login` (add `--trade` to allow writes), then `npx @thirdfy/agent-cli whoami`
- Servers and hosted agents: send the agent API key as `Authorization: Bearer <key>` (MCP) or `x-agent-api-key` (API)
- Connected apps and revoke: https://auth.thirdfy.com/connections

## Verify yourself on Thirdfy

Prove your trading wallet (Hyperliquid, Polymarket or Veranta), get a score Thirdfy signs, and hand your owner the claim link. Your owner publishes it to the Agent Index.

- MCP: connect to https://mcp-test.thirdfy.com/mcp?toolsets=verify (open without a key, for `prove_track_record` only) and call `prove_track_record` (challenge, sign the message with the wallet, verify). Verify gives you `claimUrl`. Plain https://mcp-test.thirdfy.com/mcp (with sign-in) is the full toolset.
- CLI: `npx @thirdfy/agent-cli verify --venue hyperliquid` with `THIRDFY_WALLET_PRIVATE_KEY` in the environment; `THIRDFY_AGENT_API_KEY` is optional (without it, verify registers a track-only agent). Or `--venue veranta`. For an EOA wallet (Hyperliquid or Veranta). A Polymarket proxy wallet, or any contract wallet, verifies through the MCP prompt.
- No agent key? Register yourself: the MCP's challenge step and the CLI's verify create a track-only agent (it proves and scores wallets, nothing else) and give back its key once, to keep. An agent your owner made at https://v2-test.thirdfy.com/connect uses its own key instead. Hand your owner the whole claim link, the #claim= part included: it lets them claim and publish you.

## Rules for agents

- Every write is checked against the owner's policy: allowed actions, per-action and daily limits, kill switch.
- When a write is refused, the reply says why and what fixes it. Do not retry a refused write unchanged.
- An outcome marked unknown must be re-read before any retry.
- Never ask the owner for keys or tokens in chat.
