Cursor

Cursor reaches your devices through silan mcp, Silan’s MCP server, written into Cursor’s global MCP settings by the Silan app. Status: supported. It is proven with a real Cursor on a Mac with no phone attached: Cursor listed Silan’s 16 core tools. Cursor acting on a phone from start to end is still owed, as it is for every connected app.

Connect an app, step 1 of 3, with the Cursor row.

Setup

1. Open Connections in Silan’s sidebar, or setup’s Your AI tools. Press Connect an app, then Connect on the Cursor row. The row shows Connect only when Cursor is on this Mac.

2. Silan asks Do you test your own app with Cursor? Just my devices gives the core set of 16 tools. Test my app gives the testing set of 27, with installs, recordings and test pushes.

3. Silan writes one entry, mcpServers.silan, into ~/.cursor/mcp.json:

   {
     "mcpServers": {
       "silan": {
         "type": "stdio",
         "command": "/Applications/Silan.app/Contents/Helpers/silan",
         "args": ["mcp"],
         "env": {}
       }
     }
   }

   Test my app writes "args": ["mcp", "--profile", "testing"]. Any other server in the file, and its keys, stay byte for byte. The first change keeps a copy at ~/.cursor/mcp.json.silan-backup. No key is written.

4. Quit Cursor and open it again. Press Command Q, then open Cursor. A Cursor that was open before Connect does not see Silan.

5. In Cursor’s chat, type Use Silan to list my devices. On its first tool call Silan shows Cursor wants to use your devices, with who signed it. Press Allow, Allow this time or Don’t allow.

Try it

A first prompt for Cursor’s chat:

Use Silan to take a screenshot of my iPhone and describe what is on the screen.

You should see Cursor call list_devices, then observe, and describe the screen from the element list and the picture. The first call brings the Allow sheet in Silan. From Cursor’s command line you can also list the tools Silan gives it:

cursor-agent mcp list-tools silan

With the core set it prints 16 tool names, list_devices and observe among them.

Limits

• Cursor acting on a phone from start to end is not yet proved on a real device. The proof so far is the tool list and the written config, with no phone.
• The testing set shows 27 tools over Connect: the five scenario tools are not served over XPC.
• Silan must be open on this Mac to ask you. With Silan closed, the call ends at once with Open Silan on this Mac to allow Cursor.
• ~/.cursor/mcp.json must be a JSON object, and mcpServers in it an object. Silan leaves any other file alone and tells you to fix it first.
• Disconnect on the row takes the silan entry out of ~/.cursor/mcp.json and leaves your other servers as they were, with mcpServers empty when Silan was the only one.
• A risky step answers APPROVAL_REQUIRED until you say yes in Silan. See Safety.

Proof

Proved on this Mac with no phone, 31 Oct 2026, by a Silan worker, with a real Cursor command line: Connect (Just my devices) wrote ~/.cursor/mcp.json, and cursor-agent mcp list-tools silan listed the same 16 tools while signed out. Run 20261031-140512-62730, pictures connect-*.png. On 24 Oct 2026 one click wrote silan into a file that already held another server and its key and kept them byte for byte, run 20261024-042236-97156. Source: verify-silan feature map, connections.
