MCP server for Pentool — the local AI assistant for web pentesting
PyPI version Python License: AGPL-3.0 Install: uv Open in GitHub
A self-contained stdio JSON-RPC 2.0 server that brings AI capabilities to any MCP client — first of all to Pentool (BYO-LLM: picking checks, bypassing WAF, finding non-obvious endpoints). Installed with uv in one command.
Why a separate package
MCP is the open protocol for connecting LLM
models to tools. pentool-mcp-server encapsulates Pentool's MCP layer as a
reusable PyPI package: attached locally (stdio), no network, no ports, installs
in seconds, no heavy dependencies.
🔗 Built for Pentool
This server is the MCP component of Pentool, a professional web-security testing terminal (Burp-compatible proxy, scanner, spider, intruder — all in a TUI). It powers Pentool's AI:
- 🎯 picking the relevant scan checks for a concrete target;
- 🛡 WAF bypass / payload suggestions;
- 🕷 finding non-obvious endpoints during spider crawling.
Try the full stack:
uv tool install "pentool[ai]"→pentool ai setup→pentool.
⚡ Quick start (uv)
# Install uv (if not present): https://docs.astral.sh/uv/
curl -LsSf https://astral.sh/uv/install.sh | sh
# Standalone — just the MCP server
uv tool install pentool-mcp-server
pentool-mcp-server --version
# Or together with Pentool and its AI extras
uv tool install "pentool[ai]"
Health check (stdio):
echo '{"jsonrpc":"2.0","id":1,"method":"ping"}' | pentool-mcp-server
# → {"jsonrpc": "2.0", "id": 1, "result": {"status": "ok"}}
uv is the standard install path — isolated environment, exactly how Pentool itself is installed. It keeps the server out of your system Python.
🚀 Deploy on a VPS / in a container
The server opens no ports and runs as a local subprocess — safe on any host. With uv it stays out of the system Python:
uv tool install pentool-mcp-server

🔒 Security
- No network by default.
pentool-mcp-serverlistens only on stdio (stdin → stdout) inside the local process. External access is impossible — neither from other processes nor from another host. - Do not expose it over TCP/0.0.0.0 without auth. If run on a network port
outwardly, anyone able to write to stdin/port gets
tools/call generate(resource usage + sending target data to the LLM). MCP has no built-in authentication — bind to127.0.0.1and gate via a firewall. - Target privacy. Data (URL, payload) leaves the host only if an external LLM provider is connected; with a local GGUF model the traffic stays on the machine.
More — docs/GUIDE.md.
🗺 Roadmap
- stdio JSON-RPC 2.0 server (initialize / tools/list / tools/call / ping)
-
generate,health,configuretools - real LLM runner (llama-cpp-python) in
model.py - optional TCP mode with HMAC auth
