graphql_cop · PenTest MCP Server MCP: Risk & Policy

WHAT IT DOES

What graphql_cop does on PenTest MCP Server

AI agents invoke graphql_cop to trigger actions in PenTest MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why graphql_cop needs a policy

This tool actively executes security scans against GraphQL endpoints, probing for vulnerabilities. It is part of a pentesting framework that integrates over 30 security tools for automated vulnerability scanning. Running active scans against targets constitutes executing external operations with potentially significant impact, especially if misused against unauthorized targets.

From the tool's definition GraphQL security scanner — runs automated security scanning against GraphQL endpoints as part of a penetration testing server
