Install in Cursor
Install Levirge Brain in Cursor as a plugin from the levirge/brain marketplace, or paste one block into mcp.json, then sign in.
The plugin is the recommended route: four clicks, no file editing. It adds the
server and the /brain:* commands.
Install the plugin
1 · Add the marketplace
Open Customize, click the All dropdown by the search box, and choose Add Marketplace → Import from Github.
2 · Import the repository
Type the repository, leave scope on User, and click Import:
levirge/brain3 · Add the plugin
Click Add next to brain.
4 · Sign in
Open the MCPs tab and click Authenticate. Sign in when the browser opens.
Server only
Open Customize → MCPs, click New MCP Server, and paste this into
~/.cursor/mcp.json:
{
"mcpServers": {
"brain": { "url": "https://brain.levirge.com/mcp" }
}
}Back on the MCPs tab, click Authenticate next to brain and sign in.
Put the same file at .cursor/mcp.json inside a project to enable it there
only.

Troubleshooting
The MCPs tab says "Needs authentication". That is the first-run state. Click Authenticate next to brain and sign in when the browser opens.
The plugin shows "Add" again after I added it. The marketplace filter may be on a different source. Open the dropdown by the search box and pick Levirge Brain.
It works in one project but not another. A .cursor/mcp.json inside a
project takes precedence over the global ~/.cursor/mcp.json. Check which one
the project is using.
I connected, but there are no Brain tools. Clients read the tool list once, when they connect. Quit and reopen the app so it reconnects.
