git_push · Git MCP Server MCP: Risk & Policy

WHAT IT DOES

What git_push does on Git MCP Server

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

WHY IT NEEDS A POLICY

Why git_push needs a policy

git_push uploads commits to a remote repository, modifying remote references. While this is a write operation (not locally destructive), it can have significant blast radius by overwriting remote branches, affecting other collaborators, and potentially breaking CI/CD pipelines.

From the tool's definition Push local changes to a remote repository. Uploads local branch commits to the remote repository, updating remote references.

Verdict

git_push Rate-limited

git_push 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.
