git_add · MCP File & Git Manager Server MCP: Risk & Policy

WHAT IT DOES

What git_add does on MCP File & Git Manager Server

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

WHY IT NEEDS A POLICY

Why git_add needs a policy

git_add modifies the index/staging area by selecting which changes will be included in the next commit. This is a write operation because it changes state (what Git tracks for commit), but it is reversible—files can be unstaged with git_reset or git_rm --cached. It does not execute arbitrary code, delete data, or move money.

From the tool's definition Tool name 'git_add' and description 'Stage files for the next commit' indicate modification of Git's staging area, which is a reversible write operation that changes repository state but does not delete or permanently alter files.
