What git_apply_patch_file does on GitHub
AI agents use git_apply_patch_file to create or update resources in GitHub, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GitHub environment.
Why git_apply_patch_file is rated Medium
Applying a patch file modifies repository content (creates or updates files) but does not irreversibly delete data or destroy the repository state. Changes can be reverted via git reset or subsequent commits. While high-severity due to potential code injection or unintended file modifications affecting production code, this is a Write operation rather than Destructive.
From the tool's definition Tool name 'git_apply_patch_file' and description 'Git apply patch file' indicate application of patches to a repository's working tree and/or index. The git apply command modifies files in the repository, creating or altering content reversibly.
Attacks that exploit this kind of access
The rule that runs git_apply_patch_file safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GitHub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For git_apply_patch_file, this is the rule to start with:
git_apply_patch_file stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect GitHub, apply this rule, and every git_apply_patch_file call is checked against it from then on.
