AI-native HTTP security testing MCP server — 17 tools with raw HTTP/1.1 + HTTP/2 control
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.

Real v1.2.0 MCP session against a synthetic loopback fixture: one request, response-side
filtering, stored search, and named retrieval. The capture and renderer are reproducible
from demo/ with an activated free or Pro license; no live target is
involved.

The HTTP tools cover:
send (HTTP/1.1), send_h2 (HTTP/2), fetch, import (Burp / HAR), export (curl / python / requests)hunt, scope, save, search, session, profileintruder (sniper, battering ram, pitchfork, cluster bomb), race (single-packet), chain, paralleloob with Interactsh integrationencode (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.
Each release includes checksums.txt. Verify before running:
