Crypto Due Diligence
Screen a new token for red flags and keep signals, and find a wallet's self-declared public name.
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢screen_token(chain, token, github_url, deployer)
Use this when the user gives a token address and asks "is this a rug?", "screen this coin", "who is the dev?" or what to check before buying. Pass chain (solana, ethereum, base, bsc, arbitrum, polygon, avalanche, optimism) and token (contract or mint address). Optionally pass github_url and deployer. Returns each signal as red_flag, keep_signal, not_seen or unknown, with a detail line and a source link, a reading (many_red_flags, some_red_flags or no_red_flags_seen), and the X links for a manual check. It reads public sources only and never says a token is safe. Not financial advice.

}🟢wallet_identity(address)
Use this when the user asks whether a wallet address has a public name, such as a token deployer or a known trader's wallet. Pass address (0x or Solana). Returns the ENS primary name when it resolves back to the address, and the Farcaster account that verified the address, both self-declared by the owner. It cannot search by a person's name and never links a wallet to a private person.

}🟡submit_feedback(kind, message, tool, error)
Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
