Watchdog MCP

Watchdog MCP is a community Model Context Protocol server that provides security checks for Solana programs and EVM contracts. It enables agents to verify authority, check dependency advisories, and scan repositories before signing or deploying. The server uses the x402 protocol for per-call payments in USDC, allowing automated security due diligence with configurable budget limits.
