`anywidget-mcp` runs [AnyWidgets](https://anywidget.dev/) inside AI
conversations. Interact with a Python widget, then let the model respond to its
current state. Connect through a host that supports
[MCP Apps](https://modelcontextprotocol.io/extensions/apps/overview), the Model
Context Protocol extension for interactive interfaces.

It also exposes widgets already running in a notebook as
[WebMCP](https://webmachinelearning.github.io/webmcp/) tools for browser agents,
including notebooks running Python in WebAssembly.

- **Bring existing widgets.** Serve widgets from a package or reuse the ones you
  develop in Jupyter and marimo.
- **Accept conversational input.** Typed Python factories become tools that
  create a fresh widget for each call.
- **Share selected state.** Python validates interactions, and you choose which
  values the model can read.
- **Explore large datasets.** Serve [query-backed viewers](https://peter-gy.github.io/anywidget-mcp/large-widgets)
  such as Embedding Atlas and share their current filter with the model.
- **Compose interfaces.** Expose several tools, return a group of wid…
