Cursor

Add the server URL and approve in the browser (Cursor handles OAuth itself, including reconnect). Static key config still works as a fallback.

1. 1

   Connect with OAuth (recommended)

   Add a remote server with the URL below — Cursor opens Unitpost in the browser to approve. No key to copy. Your client opens Unitpost in the browser — pick a workspace, approve the scopes, and you're connected. Tokens refresh automatically. If Cursor ever signs you out, the Authenticate button re-runs the same approval (a 401 from us triggers its reconnect).

   JSON

   {
     "mcpServers": {
       "unitpost": {
         "url": "https://mcp.unitpost.com/mcp"
       }
     }
   }

   Prefer this over pasting secrets. To pin credentials instead, add an auth object with CLIENT_ID: cursor-oauth (public client, PKCE — no secret needed).

2. 2

   Reload and verify

   Reload MCP servers in Cursor. unitpost should show connected with tools like email_send, email_campaigns_send, email_domains_verify.

3. 3

   Send a test

   Ask the agent to send a test email from a verified domain, then confirm it in Unitpost Activity.
