About
Cal.com scheduling MCP server: manage bookings, event types, and availability.
Security Report
This is a well-structured Cal.com MCP server with proper authentication, secure credential handling, and good input validation. The server uses lazy credential loading (credentials only required at tool call time, not at startup), stores the API key in environment variables only, and implements proper URL encoding for path parameters. Minor code quality observations around broad error catching and logging practices do not significantly impact the security posture. Supply chain analysis found 4 known vulnerabilities in dependencies (1 critical, 3 high severity). Package verification found 1 issue.
