Security Notes
The server employs robust practices including Zod for input validation, JWTs for authentication, and Solana signature verification. It integrates Faremeter for x402 payment enforcement and uses `@modelcontextprotocol/sdk` for MCP server functionality with DNS rebinding protection. Dynamic MCP tool schemas infer types from sample data, which is generally safe. Local image storage for AI-generated content (served publicly) introduces a potential risk if `BASE_URL` is misconfigured or if malicious content could be generated and served. Overall, good security hygiene is demonstrated, but thorough configuration and monitoring are essential for production.
