mcp_git_restore_file · Local Code MCP: Risk & Policy

WHAT IT DOES

What mcp_git_restore_file does on Local Code

AI agents use mcp_git_restore_file to create or update resources in Local Code — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Local Code environment.

WHY IT NEEDS A POLICY

Why mcp_git_restore_file needs a policy

The tool reverts file changes, which is a Write operation (modifies data reversibly). It's not Destructive because git restore can be undone by re-applying changes or restoring again from another state. Severity is medium because while it can discard work, it operates within version-controlled scope with undo capability and limited blast radius compared to destructive operations.

From the tool's definition Tool description states 'Restore a changed file with git restore -- <file>', which reverts file modifications to a previous git state. This is a reversible write operation that modifies file contents.
