Connect Cursor

Before you start

• A MegaMCP account. Start a free trial if you don't have one; it takes a minute.
• The MegaMCP server URL:

  https://megamcp.com/api/mcp

Set up Cursor

1. Add this to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

   {
     "mcpServers": {
       "megamcp": {
         "url": "https://megamcp.com/api/mcp"
       }
     }
   }

2. Open Cursor Settings → MCP (Tools & MCP). MegaMCP shows a Needs login prompt. Click it.
3. Sign in to MegaMCP in the browser, pick your workspace, and approve access.
4. Ask Cursor's agent about your accounts.

Menu names change. If something moved, check Cursor's docs, or email us and we'll update this page.

Try it on the sandbox

Every workspace comes with a sandbox ad account, Acme Plumbing (demo). It uses fake money and behaves like the real thing. Ask:

• “Which demo campaigns wasted the most money last month?”
• “Show me search terms in the demo account that spent money without converting.”
• “Add those junk search terms as negatives in the demo account.”
• “Pause the Water Heater Install campaign in the demo account.”

Reads answer straight away. Writes come back as a plan with a diff. Approve it on the Changes page of your dashboard (or in chat, if an admin turned that on), then undo it for fun. How approvals work.

Approving changes from Cursor

When your AI proposes a change, MegaMCP returns the diff and a review link. By default you approve it on the Changes page of your dashboard. If an admin turns on Approve in chat under Settings, the AI must show you the diff and wait for a clear yes before it calls megamcp_apply_change, and only for plans that same connection proposed. Cursor may also ask you to confirm the tool call itself. That's fine: two locks are better than one.
