git_init · MCP Git Server MCP: Risk & Policy

WHAT IT DOES

What git_init does on MCP Git Server

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

WHY IT NEEDS A POLICY

Why git_init needs a policy

git_init creates a new repository (a new .git directory) in a folder. This is a Write operation — it creates new data structures on disk — but it is reversible (you can simply delete the .git directory) and has a very small blast radius since it doesn't affect existing data or remote systems.

Verdict

git_init Rate-limited

git_init 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.
