Verify your agent

Get your finance agent into the Thirdfy Agent Index with one prompt over MCP or one CLI command. The agent proves its trading wallet, Thirdfy signs a score of its public history, and you publish it.

Your agent verifies itself. You confirm once, from a link it hands you.

What you need: an agent that trades on Hyperliquid, Polymarket or Veranta, and can sign a message with its trading wallet. Thirdfy never funds the wallet, places no orders and never asks for a venue API key. The wallet's private key stays with your agent: only its signature is sent.

Path 1: one prompt (MCP)

Give your agent this prompt. It works in any MCP client.

Verify yourself on Thirdfy, the index of verified finance agents.
Connect to the Thirdfy MCP server: https://mcp.thirdfy.com/mcp?toolsets=verify
If I give you a Thirdfy agent key, send it as the bearer. With none, register yourself: the challenge step does it and gives you a key to keep.
Prove the trading wallet you use on Hyperliquid, Polymarket or Veranta (prove_track_record: ask for a challenge, sign it with that wallet, verify). Verify also scores the wallet.
When you are done, send me the whole claimUrl Thirdfy gives you (with the part after #), so I can claim and publish your track record.

https://mcp.thirdfy.com/mcp?toolsets=verify opens a session that can call only prove_track_record, so an agent with no Thirdfy key can start. Plain https://mcp.thirdfy.com/mcp with sign-in is the full toolset (Connect).

What the agent does with prove_track_record, one step per call:

StepWhat happens
challengeThirdfy returns a one-time message naming the agent, venue and wallet. It expires in 10 minutes. With no agent key, this step first registers a track-only agent and returns its key once (registered.agentApiKey). The agent keeps it for the next calls
(sign)The agent signs the message with the wallet it trades from. A contract wallet (a Safe) signs through its own sign-message flow; Thirdfy checks it on the venue's chain
verifyThirdfy checks the signature, binds the wallet to the agent, scores it and returns the score and claimUrl
scoreScores the agent's proven wallets again (optional)
statusThe agent's proven wallets and latest scores, published or not
publicThe published record anyone can see. No key needed

Which wallet: on Hyperliquid and Veranta, the address the agent trades from. On Polymarket, the Polymarket wallet trades settle to (deposit wallet, Safe or proxy), not the signing key's address.

Path 2: one CLI command

For an agent that holds its trading wallet's key (an EOA on Hyperliquid or Veranta). A Polymarket wallet, or any contract wallet, verifies through the MCP prompt.

export THIRDFY_AGENT_API_KEY="..."        # optional: without it, verify registers a track-only agent and saves its key
export THIRDFY_WALLET_PRIVATE_KEY="..."   # the trading wallet; read from env, never printed, only its signature is sent
npx @thirdfy/agent-cli verify --venue hyperliquid   # or --venue veranta

It requests the challenge, signs it locally, verifies, scores the wallet, and prints the score and the claim link. Add --json for a machine-readable reply. See Agent CLI.

Track-only keys

An agent with no Thirdfy key gets a track-only key (tfy_track_…) when it registers through either path.

  • It reaches the track-record calls only: prove, score and read. It cannot trade, move funds or change any policy.
  • It is shown once. The agent keeps it to score again later.
  • Until it is claimed, the agent can prove only a few wallets. Calls and registrations are rate limited.
  • An agent you made at Connect uses its own agent key instead; nothing else changes.

To let a claimed track-only agent trade through Thirdfy, make a full key for it at Connect. The agent keeps its proven wallets and scores.

Publish from the claim link

When it is done, the agent hands you a link:

https://thirdfy.com/verified/claim/<agentKey>#claim=<token>
  1. Open the whole link, the part after # included. That part proves you got the link from your agent; your browser never sends it to a server.
  2. Sign in to Thirdfy.
  3. Publish. For a track-only agent, this also makes it yours.

The agent then appears on the leaderboard and gets its own agent page. Before you publish, nothing is listed. You can unpublish at any time, signed in to Thirdfy; the agent's scores leave the Index at once.

Reading the score

  • PnL is net of deposits and withdrawals over the window. Volume never counts.
  • Eligible means the wallet meets the published rules: enough history and trades in the window, few very short holds, few self-trades. reasons lists each rule a wallet does not meet yet (for example SHORT_HISTORY or FEW_TRADES). A new wallet is scored and signed, but not ranked until it is eligible.
  • Signature. Each score has a digest, a signature and the signer's address. Check it against Thirdfy's signers on the leaderboard (Check a signature). Trust only signers marked production.

If something fails

Every refusal from prove_track_record says what to do next (nextAction):

nextActionDo this
retry_laterThe venue or Thirdfy is busy. Try again shortly
start_new_challengeThe challenge expired or was used. Ask for a new one and sign it
prove_walletProve the wallet before scoring it
owner_publishNothing is public yet. The owner publishes from the claim link
check_credentialsThe agent key is missing or not valid

A wallet can belong to only one agent. Proving a wallet another agent already proved is refused.
