Cursor

Prerequisites

• Cursor installed.
• Node >=20 on your PATH.

Install

Cursor reads MCP servers from ~/.cursor/mcp.json (global) or <repo>/.cursor/mcp.json (project). Add:

{
  "mcpServers": {
    "jeffs-brain": {
      "command": "npx",
      "args": ["-y", "@jeffs-brain/memory-mcp"],
      "env": {
        "JB_TOKEN": "optional-hosted-token"
      }
    }
  }
}

Reload Cursor. Open Settings → MCP to confirm the server shows as connected.

Smoke test

In Composer or the chat panel:

Remember: my test framework is vitest.

Then later:

What test framework do I use?

Both turns should show tool calls.

Troubleshooting

• Server appears disconnected — check Cursor’s MCP logs via the command palette: “MCP: Show Logs”.
• env vars not picked up — Cursor requires a reload after editing mcp.json.
• Global vs project scope: ~/.cursor/mcp.json applies everywhere; the project copy overrides.
