MCP support

Provides a remote Streamable HTTP MCP server at `https://mcp.limrun.com/mcp`. MCP clients can create, operate, inspect, and delete cloud iOS simulators and Android emulators.

Configuration

Remote servers need no local install. Pick your client, then copy the config or install in one click.

Limrun MCP Server

https://mcp.limrun.com/mcp is Limrun's remote MCP server. Connect it once and your agent can create cloud iOS simulators and Android emulators on demand, drive them through screenshots and the accessibility tree, and delete them when done. Devices are real simulators/emulators running in Limrun's cloud, not mocks.

This repository is the listing home for the server. The server is a hosted, remote streamable-HTTP MCP server; there is nothing to install from here.

What it does

  • Create and manage devices: create-ios-simulator, create-android-emulator, list-instances, get-instance-status, delete-instance (instances also self-terminate on inactivity).
  • Drive iOS: ios-use (tap, type, scroll, action chains), ios-app (list/launch/ terminate apps), ios-open-url, ios-logs, ios-screenshot-and-element-tree.
  • Drive Android: android-use, android-open-url, android-screenshot-and-element-tree.
  • Apps and skills: list-apps (pre-installable app assets), get-agent-skill (step-by-step CLI procedures for builds and anything touching local files, which stay on the lim CLI).

Configure

The endpoint is https://mcp.limrun.com/mcp (streamable HTTP, stateless). Auth is OAuth sign-in on first use, or a Limrun org API key as a bearer token for headless use. Sign up at limrun.com.

VS Code / Copilot (mcp.json):

{
  "servers": {
    "limrun": { "type": "http", "url": "https://mcp.limrun.com/mcp" }
  }
}

Claude Code:

claude mcp add --transport http limrun https://mcp.limrun.com/mcp

Any other MCP client that speaks streamable HTTP works the same way; the server advertises its authorization server through standard discovery metadata, so OAuth-capable clients find the sign-in flow on their own.

Use

Ask your agent things like:

  • "Create an iOS simulator and show me a screenshot."
  • "Open example.com on it and tap the first link."
  • "Install my app from the asset list and walk through the signup flow."
  • "Clean up all my running devices."

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
