This MCP server performs a pre-interaction risk check for any EVM contract/token before an agent approves, swaps, or trusts an address. It provides a single tool, check_contract(address, chain="base"), and is described as having zero dependencies.
🛠️ Key Features
Determines whether the address is a contract vs an EOA/self-destructed account
This MCP server is free (run it locally / via your client). For server-side, batch, or no-install use, the same engine is a pay-per-call x402 HTTP API — POST https://eltociear-contract-guard.hf.space/check ($0.005 USDC on Base, no signup). Your agent's wallet pays per call.
