A Python code obfuscator built with AST-based transformations. **Supports Python 3.9 through 3.14**. Provides reliable name mangling, string
If you already use Pyobfus, the pyobfus mcp server is the piece that lets your assistant work with it directly. 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.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Installation — The Installation tool exposed by this serverExample — patient_age = 55 patient_score = 150 risk = calculate_risk(patient_age, patient_score) print(f"Risk score: {risk}")Setup — The Setup tool exposed by this serverTesting — The Testing tool exposed by this serverRecommendations — The Recommendations tool exposed by this serverConfiguration is passed through the environment: SECRET_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Installation goes through your MCP client rather than a global install: point it at pyobfus-mcp on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Pyobfus's toolset — Installation, Example, Setup and 2 more — is a fair guide to whether it matches your workflow. It is maintained by zhurong2020; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
