Connect ModelBrain to Cursor
Open ModelBrain's Client Setup and click Set up Cursor: it writes Cursor's global MCP entry automatically. No project folder needed for this to work.
Steps
- Install ModelBrain if you haven't yet (macOS).
- Open ModelBrain's Client Setup. From the menu bar / tray icon, choose Client Setup….
- Click Set up Cursor on its card. This alone is enough for Cursor to use ModelBrain, with no folder picker and no project selection required.
- Refresh MCP servers in Cursor Settings, or just restart Cursor.
- Optional: add it to one project's rules too. The card's Add to this project… button opens a folder picker for a per-project rule file. Cancelling it changes nothing; the global setup above still works without it.
Questions
Do I have to pick a project folder to use ModelBrain in Cursor?
No. Set up Cursor writes a global MCP entry with no folder picker involved. The optional Add to this project… button is a separate, per-project rule file: useful, but not required.
What if I cancel the project-folder picker?
Nothing happens beyond that. The global setup from Set up Cursor is untouched, and there's no fallback copy-to-clipboard step.
How do I know it's connected?
Check Cursor's MCP server list in Settings, or just ask it to remember something and recall it back in a new chat.
