warden402-mcp

A community MCP server providing pre-execution security for AI agents on the Base blockchain. It allows agents to guard tokens, transactions, and addresses by checking for risks like honeypots, OFAC sanctions, and contract vulnerabilities. It returns deterministic risk scores and remediation advice, and includes a firewall for enforcing per-agent spending policies.
