git_commit · Git Commit MCP Server MCP: Risk & Policy

WHAT IT DOES

What git_commit does on Git Commit MCP Server

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

WHY IT NEEDS A POLICY

Why git_commit needs a policy

git_commit creates new commits in the repository, which are write operations that modify repository state irreversibly at the Git level (though technically Git maintains history, commits themselves cannot be undone without a separate revert operation). This is categorized as Write rather than Destructive because commits are meant to preserve code changes and create an audit trail, not erase data.

From the tool's definition Tool performs 'git commit' which creates immutable records (commits) in the repository version control history. The description states '记录代码提交' (record/log code commit), confirming it writes/creates data in the repository.

Verdict

git_commit Rate-limited

git_commit 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.
