Manage Xcode simulators.
A Model Context Protocol (MCP) server that provides structured access to iOS Simulator management via xcrun simctl
commands.
Prerequisites:
curl -LsSf https://astral.sh/uv/install.sh | sh
Run directly with uvx:
uvx simctl-mcp-server
Prerequisites:
Clone and install:
git clone https://github.com/nzrsky/simctl-mcp-server
