Configure the plugin with the settings below
Plugin Name
eMCPCommand (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
Install via npm or Bun (npm i emcp or bun add emcp). You can run provided examples (bun run example:basic, bun run example:auth, etc.). Create a server instance by passing an authenticationHandler function and use server.use() to add custom middleware that runs before and after the standard MCP handler.
