Setting up Uno Platform MCPs

To get started with GitHub Copilot CLI:

Install Copilot CLI
Start Copilot CLI
Type /mcp and register the following:
1. Unique Name: uno
2. Server Type: HTTP
3. URL: https://mcp.platform.uno/v1
4. Skip HTTP Headers and leave tools to *
Type /mcp again and register the following (app-specific MCP):
1. Unique Name: uno-app
2. Server Type: Local
3. Command: dotnet dnx -y uno.devserver --mcp-app
4. Skip Environment Variables and leave tools with *

Important

The uno-app MCP may fail to load unless Copilot is opened in a folder containing an Uno Platform app.

Setting up the Uno Platform Skills

Uno Platform ships a catalog of agent skills — covering areas such as MVUX, navigation, Uno Toolkit controls, theming, and UI testing — bundled in the uno-platform-studio plugin. Once installed, Copilot CLI automatically selects the relevant skills as it works on your prompts.

From a terminal, install the plugin:

copilot plugin marketplace add unoplatform/studio
copilot plugin install uno-platform-studio@uno-platform

For the full skill catalog, update instructions, and other installation options, see Skills & Plugins.
