git_fetch_cli · Git Memory MCP Server MCP: Risk & Policy

WHAT IT DOES

What git_fetch_cli does on Git Memory MCP Server

AI agents invoke git_fetch_cli to trigger actions in Git Memory MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why git_fetch_cli needs a policy

This tool executes a CLI command (git fetch) against a repository. While git fetch is typically a read/non-destructive operation that downloads remote refs, it 'runs' an external CLI command whose effects depend on arguments and could trigger side effects (e.g., updating remote-tracking branches, triggering hooks). The 'Execute' category applies because it runs an external CLI command.
