• Audit agent configuration files and pre-deploy checklists against security best practices to identify gaps.
• Fetch and validate public URLs for security headers, redirects, and cookie flags without storing response bodies.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
