Contract Guard MCP

A community MCP server that performs pre-interaction risk checks on EVM contracts and tokens. It detects if an address is a contract or EOA, identifies upgradeable proxies and EIP-7702 delegated EOAs, retrieves ERC20 metadata, and audits ERC20 allowances for unlimited approval risks. It supports Base and Ethereum chains using pure public JSON-RPC with zero dependencies.
