arb-mcp-server

The server loads all sensitive credentials (API keys, database URL) from environment variables, which is good practice. Database interactions use parameterized SQL queries, mitigating common SQL injection risks through data values. The process for updating discovery documents correctly maps internal Python parameter names to database columns, and explicitly parses/re-dumps JSON input, further reducing injection vectors. External API calls are handled via standard HTTP requests with API keys in headers. No use of 'eval' or other obviously dangerous functions was found. The main security concern would be improper configuration of AWS S3 bucket policies (e.g., overly permissive public access) for image hosting, but this is an infrastructure concern outside the code itself.
