mcpcheck
A webcheck.xyz-style scanner for remote MCP servers.
Enter the URL of an MCP server (Streamable HTTP or SSE transport) and get a dashboard of checks:
- Connectivity & Handshake — protocol negotiation, server info, advertised capabilities.
- Tools, Resources & Prompts — full inventory with schemas.
- Security Heuristics — prompt-injection-style wording in tool descriptions, tools that may expose sensitive capabilities (exec, filesystem, network), missing descriptions, plaintext transport.
- Network & TLS — certificate validity, HTTP security headers, CORS policy.
- License Information — presence of a LICENSE file or license mention in server instructions.
Development
npm install
npm run dev
Open http://localhost:3000 and paste an MCP server URL to scan.
Notes
- Only
http://andhttps://targets are accepted; scanning private/internal IP ranges orlocalhostis blocked to prevent SSRF. - Security checks are heuristic, not a substitute for a manual security review.
