Adding MCP servers

Bug Reports
1

Thanks for reporting a bug you have found in Cursor!
Please add the following info to help us diagnose your issue:

When trying to add MCP servers inside cursor i get redirected to a mcp.json i have structured it with the correct code and placed it inside root directory. But no servers is shown in Cursor/settings/mcp.
When i watch guides on youtube they get a popup modal where you can choose what service you would want to connect to and add api key.

Are the youtube guides using a different version or what could be the problem?

Latest version uses the JSON format. You can find all detalis ion follwing page

The videos are out of date unfortunately as Cursor continues development after the videos were created.

Yeah i have followed the guide but still it wont show up in the MCP tab.
I have placed the mcp.json in the project directory and also in cursor/user/mcp.

You shouldnt add it to both. Only project or global.

Did you install the mcp correctly if its a local tool?

Without sufficient info its hard to be helpful

Hey, if your servers aren’t working, share your mcp.json file, and we’ll try to help you.

  "servers": [
    {
      "name": "Supabase",
      "url": "https://qfudkpmvanlxcgcmlqhe.supabase.co",
      "auth": {
        "type": "bearer",
        "token": "postgresql://postgres.qfudkpmvanlxcgcmlqhe:[YOUR-PASSWORD]@aws-0-eu-north-1.pooler.supabase.com:5432/postgres"
      }
    }

Hey, here’s a guide for the setup. It seems you have incorrect data for MCP.
