Connect your agent

Set up VS Code

GitHub Copilot in Agent mode, via mcp.json.

1
Open ScreenTap
The MCP server runs while the ScreenTap app is open. You need GitHub Copilot in VS Code.
2
Add ScreenTap
For one project, create .vscode/mcp.json. For everywhere, run “MCP: Open User Configuration” from the command palette. VS Code uses "servers", not "mcpServers".
mcp.json
```
{
  "servers": {
    "screentap": { "type": "http", "url": "http://127.0.0.1:47811/mcp" }
  }
}
```
3
Start the server
Click Start above the screentap entry in mcp.json, or run “MCP: List Servers” and start it there.
4
Try it
Open Copilot Chat, switch to Agent mode, check the tools button lists ScreenTap, and ask:
Prompt
```
Take a screenshot of my iPhone and tell me what's on screen.
```

Not working?

Check that the ScreenTap app is open and your iPhone is connected, then restart your agent or start a new session. More fixes in Troubleshooting.
