Scope

This project is an MCP server that proxies requests to the Eureka Flows API. Security concerns include:

  • API key exposure (keys are passed via environment variables, never logged)
  • Input validation (all tool inputs validated via Zod schemas)
  • Stdio safety (stdout reserved for JSON-RPC, logs go to stderr)

Best Practices for Users

  • Never commit .env files or API keys to version control
  • Use environment variables or Claude Desktop's env config for credentials
  • Rotate API keys regularly
