Cursor

​

Connect

1. Create an API key in the Console — or reuse an identity-scoped key if Cursor should only act as one agent.
2. Add the server in either place:
   • Project — create .cursor/mcp.json in the repository
   • Global — edit ~/.cursor/mcp.json
   • UI — open Cursor Settings → MCP and add a server, pasting the same values
   {
     "mcpServers": {
       "wirebox": {
         "url": "https://api.wirebox.sh/api/v1/mcp",
         "headers": {
           "Authorization": "Bearer wb_live_your_api_key_here"
         }
       }
     }
   }
   
3. If your Cursor build cannot send custom headers, append the key to the URL instead:
   {
     "mcpServers": {
       "wirebox": {
         "url": "https://api.wirebox.sh/api/v1/mcp?apiKey=wb_live_your_api_key_here"
       }
     }
   }
   
4. Cursor detects the change automatically; if the server does not appear, restart Cursor.

What Cursor can do

• List, search, read, send, reply to, and delete email in the agent’s mailbox
• List and read iMessage conversations, and send iMessages
• Check which identity the connection acts as
