Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
crossplane-mcp-server - WIPCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Configure it as an MCP server in VS Code by adding the provided JSON block to mcp.json, or in Claude Desktop by adding it to claude_desktop_config.json. In both cases the server is started with uv running src/server.py.
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.
