mcp-template

The codebase appears well-structured and follows good practices for a template. It uses environment variables for configuration (PORT, HOST, SERVER_NAME, SERVER_VERSION), preventing hardcoded secrets. Input arguments for tools are validated against a schema, which helps prevent basic injection attacks related to tool arguments. Error handling for MCP messages is in place to avoid leaking internal server details. The default CORS configuration allows all origins, which is common for a template but should be restricted in a production environment. There are no obvious `eval` or dynamic code execution from user input for tool calls. The main minor concern is the lack of explicit connection limiting for SSE, which could be a denial-of-service vector if not managed at a proxy or application level in production.
