What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

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

license MIT - declared in the repository

npm package mcp-baepsae - unscoped; check the name against the project README before installing

registry namespace io.github.oozoofrog is GitHub-verified and matches the repo owner

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.

Is Baepsae still maintained?

Yes - as of 2026-09-18, its last commit was 2026-03-31. We re-verify nightly.

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.
