Security Report

3.5

Use Caution3.5High Risk

The ChartForge MCP server is a straightforward chart generation tool with reasonable authentication via API key. However, it has several concerning gaps: the API key is optional (falls back to empty string), lacks input validation on numeric parameters that could cause resource abuse, and provides no error handling for malformed API responses. The server's permissions (network HTTP, environment variables) are appropriate for its purpose, but the implementation quality issues and missing security controls warrant attention before production use. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
