MCP Apps UI Example

This example demonstrates MCP Apps using poem-mcpserver with a static UI resource. The UI is bundled as an HTML file and uses @modelcontextprotocol/ext-apps.

What it does

• Exposes a tool with _meta.ui.resourceUri (ui://apps/color-picker).
• Serves the UI resource via resources/read.
• Lets the UI call back into the server to set/get a color.

Run the server

From the repository root:

• cargo run -p apps-ui

Then connect your MCP host to the server over stdio and invoke color_app. The host should render the UI and allow interactive updates.
