Security Notes

The server relies on the Model Context Protocol (MCP) SDK and acts as a proxy to the JustCall API. It enforces the presence of a 'Bearer' token in the Authorization header for protected endpoints (/mcp, /sse, /sse/message). However, the server itself does not perform intrinsic validation of the token's content (e.g., JWT signature verification or API key validity). This crucial validation is delegated to the downstream JustCall API. Assuming the JustCall API's authentication is robust, the overall system is secure. No 'eval', obfuscation, or obvious malicious patterns were found in the provided source code. Hardcoded secrets are avoided by using environment variables as a fallback for API credentials.
