Security Report

5.2
Moderate5.2Moderate Risk

The CallRail MCP server uses API key authentication from environment variables or a key file, with no hardcoded secrets visible in the reviewed code. Network access to the CallRail API and file reads for the key file are proportionate to the server's purpose, and write operations include safety guards such as confirm_billing, confirm_dialing, and dry_run defaults. The review was limited to a truncated portion of server.py, so client.py and remaining tool bodies were not inspected. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
