Overview

Description from the maker (original English)

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

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Cybersecurity

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Download the maker’s .mcpb file

The link goes to the maker’s own file; we do not host or repackage it. Open the file and Claude Desktop installs it.

Run this in your terminal

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Rqwstr safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.

What can I use instead?

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.

rqwstr is free: every tool works right after install, with no account, key or sign-up.

This repository hosts the release binaries and Claude Desktop `.mcpb` bundles. The source is proprietary. Docs: [rqwstr.com](https://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/ against v1.2.0; no live target is involved.

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. Add a scope rule before sending (scope action=add type=include host_pattern=...); requests go direct unless you configure a proxy.

Tools

17 HTTP tools:

send · send_h2 · fetch · intruder · race · chain · oob · parallel · scope · session · encode · export · save · search · hunt · profile · import

Workflows

The HTTP tools cover:

  • 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. Every tool is available to everyone.

Upgrading from v2

v3.0.0 removes rqwstr setup, logout and license; an old config's [license] section is ignored. Requests now go direct unless a proxy is configured. Set [defaults] proxy = "http://127.0.0.1:8080" in ~/.rqwstr/config.toml to keep routing through Burp or Caido.

Verify a download

Each release includes checksums.txt. Verify before running:
