🚨

Known vulnerabilities in dependencies: 1 critical, 2 high

Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.

🔐

You'll be asked for 3 credentials: ALCHEMY_API_KEY, ARBISCAN_API_KEY, ETHERSCAN_API_KEY

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

// required environment variables

This server reads these from process.env. You'll be asked to provide them before it can run.

configANVIL_DEFAULT_CHAIN_ID— Default chain ID 31337

configANVIL_PORT_END— Anvil port range end 8555

configANVIL_PORT_START— Anvil port range start 8545

🔐 secretARBISCAN_API_KEY— Arbiscan API key -

configAUDIT_MCP_DB_PATH— SQLite database path ./audit-mcp.db

configAUDIT_MCP_HOST— HTTP server host 0.0.0.0

configAUDIT_MCP_PORT— Server port (default: 3000)

🔐 secretETHERSCAN_API_KEY— Optional, for source code verification
