git-remote-add · GitHub MCP Server MCP: Risk & Policy

WHAT IT DOES

What git-remote-add does on GitHub MCP Server

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

WHY IT NEEDS A POLICY

Why git-remote-add needs a policy

This tool creates/modifies repository metadata (the remote configuration) without deleting data or executing arbitrary code. It is reversible via git-remote-remove. While it could enable downstream supply chain risks if a malicious remote is added, the immediate action is configuration write, not destructive or execute.

From the tool's definition 'Adds a remote repository' – the tool modifies Git configuration by registering a new remote URL, a reversible change to the repository's remote settings.

git-remote-add Rate-limited

git-remote-add 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.
