# Third-party notices

omp-antigravity-acp-provider is an OMP-focused derivative fork/adaptation of [pi-antigravity-acp-provider](https://github.com/zacbemis/pi-antigravity-acp-provider), originally created by [zacbemis](https://github.com/zacbemis) and contributors and distributed under MIT. It vendors upstream version 0.1.15 source under `extension/vendor/pi-antigravity-acp-provider` (see `extension/vendor/pi-antigravity-acp-provider/LICENSE`) and keeps attribution.

The upstream authors retain credit for the original ACP transport, authentication, runtime installation, session restoration and MCP bridge implementation.

Its original license notice follows. The adapter adds OMP-specific registration, model selectors, lifecycle handling, tool-routing instructions and cost estimation. Published npm packages include the generated `THIRD_PARTY_LICENSES.txt` with license notices for bundled dependencies. Google runtime executables are not included.
