Contract Scanner

Scans Solidity contracts on Base and EVM chains for common vulnerabilities including reentrancy, hidden mints, backdoors, and access control flaws. Exposes four tools via MCP: scanner_analyze_contract returns a 0-100 risk score and vulnerability report, scanner_compare_contracts diffs two addresses, scanner_check_address verifies source code, and scanner_decode_calldata parses transaction input. Free tier gives you 5 scans per hour with unlimited calldata decoding. Built on ethers v6 with strict TypeScript. The author recommends calling this before your agent touches any unfamiliar contract. Part of a four-server suite designed for Base agents that also includes multi-wallet management, DeFi orchestration, and gas sponsorship tools.
