mcp-api-tools

HTTP/API testing tools for AI agents, built on the Model Context Protocol.

Make any HTTP request (GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS) with full control over headers, body, authentication, and timeouts. Returns status code, response headers, body, and timing information.

Check the health of multiple API endpoints in parallel. Returns HTTP status, response time, SSL certificate validity and expiry, and optional response body validation. Includes a summary with counts of healthy, unhealthy, and errored endpoints.

Decode a JWT token without cryptographic verification. Returns the decoded header and payload, issued-at time, expiry time, and whether the token is currently expired.

Parse a URL into its component parts (protocol, host, port, path, query parameters, hash) or build a URL from individual parts.

Analyze HTTP response headers for security posture (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy), caching directives, CORS configuration, and cookie attributes. Provides a letter grade for security. Can fetch headers from a live URL or analyze a provided headers object.
