The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_token_safety ~139
Risk-check an ERC-20 before trading it: metadata, contract + ownership status, upgradeable-proxy detection, holder concentration, and a transfer/honeypot simulation → risk signals + a score. The deep checks (concentration, honeypot) are heavy: needs NODEFLARE_API_KEY or X402_PRIVATE_KEY. Works on young chains (Zircuit, Robinhood, Plasma, Ink) that big indexers leave empty.

| token | string | yes | 0x ERC-20 contract address to check |
No output schema declared.
No examples provided.
