rqwstr
# 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](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/`](demo/README.md) with an activated free or Pro license; no live target is
involved.
## Install
### Claude Desktop (one-click)
Download the `.mcpb` for your platform from the [latest release](https://github.com/Kjopstad-IT/rqwstr-mcp/releases/latest) 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](https://github.com/Kjopstad-IT/rqwstr-mcp/releases/latest), then point your MCP client at it:
```json
{
"mcpServers": {
"rqwstr": {
"command": "rqwstr",
"args": ["serve"]
}
}
}
```
`rqwstr serve` runs the MCP server on stdio.
## 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. The free tier is the core toolset; a Pro tier unlocks the heavier offensive tools.

Scored across 18 tools
Each tool has a clearly distinct purpose: send/send_h2 for single requests, chain for multi-step flows, parallel for simultaneous, intruder for fuzzing, race for race conditions, oob for out-of-band detection, etc. Even send and send_h2 are differentiated by HTTP version. No two tools overlap in functionality.
Most tools use single-word lowercase verbs (chain, encode, fetch, hunt, etc.), but there are deviations: 'intruder' is a noun, 'oob' is an acronym, 'rqwstr_docs' uses an underscore, and 'send_h2' uses underscore. However, the overall pattern is short and descriptive, with only minor inconsistency.
18 tools is well-scoped for a comprehensive HTTP security testing toolkit. Each tool covers a distinct operation (sending, fuzzing, encoding, session management, etc.), and the number is neither too small to be useful nor too large to be overwhelming.
The tool surface covers the full lifecycle of HTTP request manipulation: creation (import, save), sending (send, send_h2, chain, parallel, intruder, race), modification (encode, session), inspection (fetch, search, export), and auxiliary functions (hunt, scope, profile, oob, rqwstr_docs). No obvious gaps for its intended purpose.
