Quorum with Cursor

Add Quorum to Cursor in one click, sign in once, and the agent can convene a panel.

Cursor's agent calls Quorum as a tool. It sends a question to a panel of models from different labs and gets back one answer plus the places the panel split.

Set up

Add to Cursor

Cursor opens and asks you to install the quorum server. Install it, then sign in to Quorum and approve access. You approve once.

To add it by hand, put this in .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "quorum": {
      "url": "https://www.quorum.dog/mcp"
    }
  }
}

Check it works

Ask the agent to call list_modes. The call is free and returns the Modes you can use.

Using it

The agent has 13 tools. Ask it to call estimate first. estimate is free and reports whether a panel is likely to help on your question. Then deliberate convenes the panel, using the model QRUM:STAN, which is Standard Mode.

A connected app on your plan pays real cost, with no Mode fee. See the Connecting FAQ.

When to use it

• A decision that is hard to reverse. Anything with a migration behind it.
• An approach you want checked. Hand the proposed approach to the panel and ask what breaks.
• A question where the seats may split. get_receipt shows which seats disagreed.

Renames, formatting and anything with one right answer go to a single model.

Use an API key instead

To bill calls to an organization, or to run without a browser sign-in, send an API key from your usage page:

{
  "mcpServers": {
    "quorum": {
      "type": "http",
      "url": "https://www.quorum.dog/mcp",
      "headers": { "Authorization": "Bearer ${env:QUORUM_API_KEY}" }
    }
  }
}

Cursor reads ${env:...} in url and headers, so the key stays in your environment. API keys always bill your organization's API account.
