anywidget-mcpBring AnyWidgets into the conversation.

anywidget-mcp opens an AnyWidget inside an AI conversation and keeps its Python state synchronized. Interact with the widget, then ask the model about your input. Each widget runs as an MCP App.

Try a multi-widget conversation ​

Requires Python 3.11 or newer. Serve Wigglystuff's ColorPicker and LiveEdit together:

uvx --with wigglystuff anywidget-mcp serve \
  wigglystuff:ColorPicker \
  wigglystuff:LiveEdit \
  --port 8010

Connect a host that supports MCP Apps. For a quick local setup, start the mcp-use Inspector in another terminal:

npx --yes @mcp-use/inspector@12.0.3 \
  --url http://127.0.0.1:8010/mcp \
  --port 7878

Open Inspector Chat, configure a model provider, then ask:

let me pick a color

Choose a color, then ask:

given my current selection help explain the HEX to RGB algo interactively

The model reads the picker's current color and opens LiveEdit for the interactive explanation. One server exposes both widgets, so the conversation can move from selection to explanation without leaving the chat.

Getting started explains the Inspector flow and other MCP clients.

Install in a project ​

Install anywidget-mcp in the Python environment that owns your widget code:

uv pip install anywidget-mcp

Next steps ​

• Getting started runs two widgets in Inspector Chat and then serves one you author.
• Model-visible state chooses which widget values the model can use.
• Pass input to widgets accepts values from the model, loads data, and combines widgets with other tools.
• Deployment runs the server for local and hosted MCP clients.
