git_remote · Git MCP: Risk & Policy

WHAT IT DOES

What git_remote does on Git

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

WHY IT NEEDS A POLICY

Why git_remote needs a policy

This tool can add, remove, or modify remote repository configurations. While 'remove' could be considered destructive, remote configuration changes are generally reversible (remotes can be re-added). However, modifying remotes could redirect pushes/pulls to unintended repositories, making misuse high severity. The primary operations are configuration writes rather than irreversible data deletion.

From the tool's definition "Add, remove, or set URL for remotes using action-based input"

Verdict

git_remote Rate-limited

git_remote 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.
