runs as local process (stdio) - runs on your machine with your user's permissions

03 · What Baepsae can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Limitations (from the README)

After granting permission, the launching process may need to be restarted before macOS applies the change. If the error persists, quit and relaunch the terminal, MCP client, or runtime process that started mcp-baepsae. For simulator targets, selector-based actions (tap / right_click with id or label) search in-app content by default. Set all: true to include Simulator chrome UI.

How do I install Baepsae?

Run `npx -y mcp-baepsae`. The README documents one environment variable (BAEPSAE_NATIVE_PATH) to set first. Set BAEPSAE_NATIVE_PATH before connecting. You can also paste the ready-made client config above.
