Setting up Uno Platform MCPs

1. Install Codex CLI using the official commands, for example:

   bashCopy

   npm i -g @openai/codex
   # or on macOS
   brew install --cask codex
   

2. Register the Uno Platform MCPs:

   bashCopy

   codex mcp add "uno" --url "https://mcp.platform.uno/v1"
   codex mcp add "uno-app" -- dotnet dnx -y uno.devserver --mcp-app
   

3. Start Codex CLI and type the following:

   textCopy

   /mcp
   

   This will show the Uno Platform tools available to the agent.

   [!IMPORTANT] The uno-app MCP may fail to load unless Codex is opened in a folder containing an Uno Platform app.
