About rog0x

rog0x is an MCP server for AI agents and developers testing HTTP APIs. It combines request execution with endpoint health checks, JWT decoding, URL parsing, and response-header security analysis.

Key features

  1. 01HTTP requests with configurable methods and auth
  2. 02Parallel API health checks
  3. 03JWT decoding without verification
  4. 04URL parsing and construction
  5. 05Security and cache header analysis

Use cases

  1. 01Inspect API responses during testing
  2. 02Check several endpoints and SSL validity
  3. 03Review JWT claims and expiration
  4. 04Assess security headers on a live URL

MCP support

Exposes HTTP and API analysis tools to MCP clients, including request execution, health checks, JWT decoding, URL parsing, and header analysis.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "rog0x-api": {
      "command": "npx",
      "args": [
        "-y",
        "@rog0x/mcp-api-tools"
      ]
    }
  }
}
Run commandnpx -y @rog0x/mcp-api-tools

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details

From the project README

@rog0x/mcp-api-tools

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

Tools

http_request

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.

api_health

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.

jwt_decode

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.

url_parse

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

header_analyzer

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.

Installation

npm install
npm run build

Configuration

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "api-tools": {
      "command": "node",
      "args": ["D:/products/mcp-servers/mcp-api-tools/dist/index.js"]
    }
  }
}
Claude Code
claude mcp add api-tools node D:/products/mcp-servers/mcp-api-tools/dist/index.js

Examples

Make a POST request:

Use http_request to POST to https://httpbin.org/post with JSON body {"key": "value"}

Check API health:

Use api_health to check these endpoints: https://api.github.com, https://httpbin.org/get

Decode a JWT:

Use jwt_decode to decode this token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...

Parse a URL:

Use url_parse to break down https://example.com:8080/api/v1?key=value&debug=true#section

Analyze security headers:

Use header_analyzer to check security headers for https://github.com

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
