Nothing serious here today

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

request

request_verification_challenge

Step 1 of wallet verification: get a fresh challenge for the user to sign. chain: "evm" or "solana". Pass agent_id (your marketplace identity) so the proof is bound to you. Present `challenge` to the user, have their wallet sign it (EVM personal_sign / Solana signMessage), then call verify_wallet_ownership with the returned `nonce` + signature. The challenge is single-use and expires (~10 min). Returns {challenge, nonce, expires_at}.

verify

verify_wallet_ownership

Step 2 of wallet verification: prove control by signing the challenge from step 1. chain: "evm" (secp256k1, 0x-hex signature) or "solana" (ed25519, base58/base64/hex). `nonce` is from request_verification_challenge; the signature must be over that exact challenge text. Pass the same agent_id you requested the challenge with — on success the wallet is linked to you and you get a session_token to pass to Tachyo's other agents (e.g. check_token_safety) to unlock connected/premium tiers. Returns {verified, address, chain, linked, session_token?, session_expires?}. Does not move funds or expose keys.

Verify — questions

Answers built from our own checks of this server.

What can Verify do?

It exposes 2 tools, read directly from the server on our last check. Among them: request_verification_challenge, verify_wallet_ownership. 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 →

Is Verify 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 254 ms. The bar chart above shows every period we have measured.

How do I connect Verify?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Verify need an API key?

No. Verify completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Verify?

It answers our handshake in 254 ms on average, which is faster than 56% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
