rt_check_callbacks
Analyzes MCP server tool schemas for callback and webhook URL parameters that lack constraints, identifying potential SSRF vulnerabilities.
Instructions
Analyze tool schemas for callback/webhook URL parameters that could enable SSRF. Checks parameter names (callback, webhook, redirect, return_url, notify_url, hook_url, etc.) and whether URL constraints (enum, pattern, format) are applied. Also scans descriptions for callback URL acceptance patterns.
