mcpsmuggler

FastMCP wrapper for the Smuggler HTTP Request Smuggling scanner, packaged for Render via Docker.

What this does

• Exposes an MCP server with a single tool: do_smuggler

• Runs the Smuggler CLI (smuggler -u <url> ...) inside the container

• Uses SSE transport on /mcp (FastMCP default)

Related MCP server: mcp-guardian

Running locally

git clone https://github.com/ozgurozkan123/mcpsmuggler.git
cd mcpsmuggler
python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
python server.py  # starts on http://0.0.0.0:8000/mcp

Render deployment (Docker)

Render will auto-detect the Dockerfile:

• Runtime: Docker

• Exposed port: PORT env (Render sets this)

• Start command: handled by Dockerfile (python server.py)

If using Render UI:

1. Create a Web Service

2. Connect this repo and choose Docker

3. Leave root directory empty, Dockerfile path = Dockerfile

4. No build/start commands needed
