How we review

Extended accessThe tool runs code or makes network calls and only reads external data.

  • Through MCP the agent creates windows and runs Python code on your computer.

This is third-party code. Review the repository files before installing.

What it does

PyWry is a toolkit for building Python interfaces with one API for three targets: a native window through PyTauri, a Jupyter widget and a browser tab. For Claude Code the repository ships a `pywry` plugin with an MCP server, the `pywry-builder` subagent, the `/pywry:doctor`, `/pywry:scaffold` and `/pywry:examples` commands, a ruff formatting hook and the `pywry-orientation` skill. A `.mcpb` extension exists for Claude Desktop. The MCP server installs with the package: `pip install 'pywry[mcp]'`. The agent can create and change PyWry windows and widgets, from charts to a chat window. An app can be built into a standalone executable with `pywry[freeze]`, and state can live in Redis or encrypted SQLite.

Who it is for. Python developers building desktop and notebook interfaces who want to hand part of the work to Claude Code.

Good fit when

  • A quick PyWry window scaffold with a chart or chat is needed at an agent request.
  • One interface must work in Jupyter, in a browser and in a native window.
  • PyWry environment diagnostics with `/pywry:doctor` are needed.
  • A Python app has to be built into a standalone executable.

Not a fit when

  • You need a Qt or Electron interface.
  • The project is not written in Python.
  • You need only web pages without Python logic.

Example request

Create a PyWry window with a price chart and a chat on the right and check the environment with /pywry:doctor.

Limitations

Python 3.10 to 3.14 is required and a virtual environment is recommended. The plugin installs from the repository marketplace and the MCP needs the package with the `mcp` extra. A native window needs a system web shell, and a browser tab with horizontal scaling needs Redis. Through MCP the agent creates windows and runs code on your computer, so work in a separate environment. Some features, such as authentication and encrypted storage, need separate package extras.

How to disable. Remove the plugin with `/plugin` and the package with `pip uninstall pywry`. Remove the MCP server entry from the client settings.

FAQ
