What io.github.zhurong2020/pyobfus-mcp does

pyobfus (pronounced as "Python obfuscator") is a modern, AST-based python-obfuscator / code-obfuscator with framework-aware presets, reverse stack-trace mapping for AI-assisted debugging, and a machine-readable JSON CLI designed for Claude Code, Cursor, and MCP agents. A transparent, open-source alternative to PyArmor.

README

pyobfus — the Python obfuscator

pyobfus (pronounced as "Python obfuscator") is a modern, AST-based python-obfuscator / code-obfuscator with framework-aware presets, reverse stack-trace mapping for AI-assisted debugging, and a machine-readable JSON CLI designed for Claude Code, Cursor, and MCP agents. A transparent, open-source alternative to PyArmor.

A Python code obfuscator built with AST-based transformations. Supports Python 3.9 through 3.14. Provides reliable name mangling, string encoding, control-flow flattening, AES-256 string encryption, and — unique to pyobfus — a reverse-mapping workflow that lets you (or your AI coding assistant) debug obfuscated stack traces without giving up the protection.

🔌 Companion MCP server: `pyobfus-mcp`

This repository ships two installable packages:

Package	What it is	Install
`pyobfus`	The Python obfuscator (CLI + library).	`pip install pyobfus`
`pyobfus-mcp`	A Model Context Protocol (MCP) server that exposes pyobfus's tools to AI coding agents.	`uvx pyobfus-mcp` (zero-install) or `pip install pyobfus-mcp`

The MCP server lives in pyobfus_mcp/ and is built on the official Model Context Protocol Python SDK (FastMCP). It registers eight MCP tools so Claude Desktop, Claude Code, Cursor, Windsurf, and Zed can call pyobfus directly from agent conversations — no shelling out:

MCP tool	Implementation	Purpose
`protect_project`	`pyobfus_mcp/tools.py`	One-call, self-verifying pipeline: scan → preset → obfuscate → byte-compile + import-smoke-test the output → return `verified: true/false`. The agent reports a green check instead of hoping the transform didn't break anything
`check_obfuscation_risks`	`pyobfus_mcp/tools.py`	Pre-flight risk scan (eval/exec, dynamic attribute, framework reflection)
`generate_pyobfus_config`	`pyobfus_mcp/tools.py`	Auto-detect framework → write a working `pyobfus.yaml`
`unmap_stack_trace`	`pyobfus_mcp/tools.py`	Reverse obfuscated identifiers in a production stack trace
`list_presets`	`pyobfus_mcp/tools.py`	Enumerate community / framework / Pro presets
`explain_preset`	`pyobfus_mcp/tools.py`	Describe what a named preset changes
`recommend_tier`	`pyobfus_mcp/tools.py`	Analyze a project and recommen
