MCP Pystub MCP Server

Python exe ビルド（PyInstaller / Nuitka / cx_Freeze）時にスタブ置換可能なパッケージを自動検出し、最小スタブコードを生成する MCP サーバー。. Exposed over MCP by the mcp pystub mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

Adding it to your client

The server ships on PyPI as mcp-pystub, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Its toolset

Everything the assistant can do here goes through one of these:

• analyze — The analyze tool exposed by this server
• generate — 出力 / Output: { "files": { "pandas/init.py": "...", "pandas/core/api.py": "class DataFrame: pass\nclass Series: pass\n..." }

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the mcp pystub mcp server does with a few real requests.

When to reach for it

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP Pystub's toolset — analyze, generate — is a fair guide to whether it matches your workflow. It is maintained by koyoyeager; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
