Connect Cursor

Connect Cursor

Cursor has two paths. The one-click deep link registers the server for you. The manual path is a small JSON file, per project or for every project. Both end at the same browser sign-in.

Before you start

• A Cloud account. Create one at thecloud.so. The connection signs in as you, so the account has to exist first.
• Cursor installed. The deep link opens the app you have installed.

The one address

There is a single MCP server address. It speaks HTTP JSON-RPC 2.0. You will paste it once:

https://mcp.thecloud.so/mcp

Steps

1. One click, if Cursor is installed Open this link and Cursor adds the server under the name the-cloud. It is a cursor:// deep link, so it only works on a machine with Cursor installed.

   cursor://anysphere.cursor-deeplink/mcp/install?name=the-cloud&config=eyJ1cmwiOiJodHRwczovL21jcC50aGVjbG91ZC5zby9tY3AifQ==

2. Or edit mcp.json by hand Put this in ~/.cursor/mcp.json for every project, or a project's .cursor/mcp.json for just that one.

   {
     "mcpServers": {
       "the-cloud": { "url": "https://mcp.thecloud.so/mcp" }
     }
   }

3. Reload and sign in Open the Command Palette and run Developer: Reload Window. The first connection opens your browser to sign in to The Cloud.

Verify it worked

Start a new chat and send one word: sync. The Cloud answers with its Charter, your memory, and a line confirming the sync. If you get that back, the connection is live and every other tool is available to that chat.

Troubleshooting

• The one-click link does nothing. The browser could not hand the cursor:// scheme to an app. Install Cursor, or use the mcp.json path above, which needs no deep link.
• The server shows up but has no tools. Reload the window again. Cursor reads tools/list on connect, and a window that was open during the sign-in can hold the empty pre-auth list.
• The tool list looks stale. Reconnect the server, or restart Cursor, so it re-reads tools/list. The Cloud adds tools often and a client caches the list from its last handshake.
• You are on Windsurf, not Cursor. Windsurf uses serverUrl instead of url and needs a static key. The snippet is on Connect into The Cloud.

Next

• Connect into The Cloud for auth, every other client, and the full tool surface.
• Tool reference for every tool and its safety class.
• Safety and consent for what your AI can do without asking, and what it cannot.
• Build on The Cloud to ship a hosted Studio app from the client you just connected.
