How to add an MCP server to Cursor

1. 1

   Open the config file

   • Global: ~/.cursor/mcp.json, used in every project.
   • Project: .cursor/mcp.json at the root of the repo, shared through git.
2. 2

   Add the server

   Paste this, or add the connectchats entry inside your existing mcpServers object:

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

3. 3

   Save and sign in

   Cursor picks up the change. Open the MCP server list (under Customize in current versions, Cursor Settings in older ones), find connectchats and sign in. Cursor opens your browser for OAuth.

4. 4

   Check the tools

   The server shows its tools once it is connected. Use its toggle to switch a server off without deleting it.

1. 1

   Ask in the Agent chat

   • "What did the team say in the WhatsApp release group today?"
   • "Find the error message Marco pasted in our chat yesterday."
2. 2

   Approve tool calls

   Cursor asks before it runs an MCP tool unless you set that tool to run automatically.

Open the Output panel, choose MCP Logs and look for the server's error. Most failures are a typo in the URL or a sign-in that did not finish.

1. 1

   Create a ConnectChats account

   Open https://connectchats.com/app and sign in with a passkey. There is no email or password to remember.

2. 2

   Link WhatsApp

   Choose Link a chat app, then WhatsApp. Scan the QR code from WhatsApp on your phone (Linked devices, then Link a device), or switch to Use a pairing code.

3. 3

   Choose the chats your AI can read

   Chats appear on the Chats page as they import. Turn on only the ones you want your AI app to see.

4. 4

   Add the server

   Add the mcp.json entry above with https://api.connectchats.com/mcp and sign in.

• A remote server needs no command or args, only url.
• Keep secrets out of a project mcp.json you commit. ConnectChats uses OAuth, so the file holds no token.
• For a server that takes an API key, add a headers object next to url.
