# OutputApplyPatchServerToolItem - Python SDK

> OutputApplyPatchServerToolItem method reference

<Warning>
  The Python SDK and docs are currently in beta.
  Report issues on [GitHub](https://github.com/OpenRouterTeam/python-sdk/issues).
</Warning>

An openrouter:apply\_patch server tool output item. The turn halts when validation succeeds so the client can apply the patch and echo an `apply_patch_call_output` on the next turn.
