Kjopstad-IT/rqwstr

AI-native HTTP security testing toolkit, shipped as an MCP server. It gives an AI agent low-level control over HTTP/1.1 and HTTP/2 — raw framing, connection pinning, intruder-style fuzzing, request racing, OOB detection, and multi-step chains — on its own Go engine, rather than wrapping a high-level HTTP client.

This repository hosts the release binaries and Claude Desktop .mcpb bundles. The source is proprietary. Docs and sign-up: rqwstr.com.

Install

Claude Desktop (one-click)

Download the .mcpb for your platform from the latest release and double-click it to add rqwstr as a Claude Desktop extension.

• macOS — Apple silicon (darwin_arm64) or Intel (darwin_amd64)
• Linux — linux_amd64 or linux_arm64
• Windows — windows_amd64

Standalone MCP server

Download the binary for your platform from the latest release, then point your MCP client at it:

{
  "mcpServers": {
    "rqwstr": {
      "command": "rqwstr",
      "args": ["serve"]
    }
  }
}

rqwstr serve runs the MCP server on stdio.

What's in the box

17 HTTP tools driven by an AI agent over MCP:

• Traffic — send (HTTP/1.1), send_h2 (HTTP/2), fetch, import (Burp / HAR), export (curl / python / requests)
• Hunt lifecycle — hunt, scope, save, search, session, profile
• Attacks — intruder (sniper, battering ram, pitchfork, cluster bomb), race (single-packet), chain, parallel
• OOB — oob with Interactsh integration
• Encoding — encode (URL, base64, JWT, and more)

Agents discover workflows through the rqwstr_docs tool. Per-hunt state lives in SQLite. The free tier is the core toolset; a Pro tier unlocks the heavier offensive tools.
