Security Report

6.2

Moderate6.2Moderate Risk

This is a well-structured MCP server for the FastSocial API with proper authentication and reasonable permissions. The code correctly retrieves the API key from environment variables, validates all tool inputs via schema, and makes authenticated requests to a legitimate third-party API. No security vulnerabilities, malicious patterns, or credential leaks were identified. Minor code quality observations around error handling and input validation do not materially impact security. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 2 high severity).
