Cursor

Give Cursor real-time web search, content extraction, and citation-backed research through the You.com MCP Server.

One-click install

Clicking the button opens Cursor and pre-fills the configuration. Cursor will trigger OAuth automatically — sign in to You.com in the browser window that opens, and the integration is live.

Manual setup

If you’d rather configure by hand, open Cursor settings → MCP → Add new server, and paste:

1
{
2
  "mcpServers": {
3
    "you-com": {
4
      "url": "https://api.you.com/mcp"
5
    }
6
  }
7
}

With an API key (skip OAuth):

1
{
2
  "mcpServers": {
3
    "you-com": {
4
      "url": "https://api.you.com/mcp",
5
      "headers": {
6
        "Authorization": "Bearer YDC-YOUR-API-KEY"
7
      }
8
    }
9
  }
10
}

Free tier (search only, no auth):

1
{
2
  "mcpServers": {
3
    "you-com": {
4
      "url": "https://api.you.com/mcp?profile=free"
5
    }
6
  }
7
}

Turn off Cursor’s built-in web search

Go to Settings → Agents and turn off the built-in web search tool. This avoids the agent picking Cursor’s lower-quality search when You.com is available, and prevents duplicate tool calls on the same query.

Quick demo

Open the agent panel and try:

Find the official Next.js 15 migration guide and pull the breaking-changes section verbatim.

Troubleshooting

• Server not appearing — restart Cursor after editing the MCP config. The reload-on-save behavior is unreliable in current builds.
• OAuth window doesn’t open — check that you don’t have a popup blocker active for cursor:// deeplinks.
• Tools show but never get called — confirm Cursor’s built-in web search is disabled (see above). The agent may be preferring the cheaper local tool.
• "type": "http" error — remove the type field. Cursor doesn’t use it.
