Connect your agent
Anything that speaks MCP, over HTTP or stdio.
Pick the transport your client supports
ScreenTap offers both. Use HTTP if your client can connect to a URL, and stdio if it can only start a program.
Streamable HTTP http://127.0.0.1:47811/mcp
stdio /Applications/ScreenTap.app/Contents/MacOS/ScreenTap --stdioHTTP clients
Most take a JSON entry with a url. The field name varies by client (url, serverUrl or httpUrl).
{
"mcpServers": {
"screentap": { "url": "http://127.0.0.1:47811/mcp" }
}
}stdio clients
Point the client at the ScreenTap app with the --stdio argument.
{
"mcpServers": {
"screentap": { "command": "/Applications/ScreenTap.app/Contents/MacOS/ScreenTap", "args": ["--stdio"] }
}
}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.
