git_stash · LocalAnt MCP: Risk & Policy

WHAT IT DOES

What git_stash does on LocalAnt

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

WHY IT NEEDS A POLICY

Why git_stash needs a policy

git stash push saves uncommitted working-tree changes to a stash stack, which is a reversible write operation. Changes are not deleted — they can be recovered via git stash pop/apply. However, misuse could cause confusion or loss of context if stash entries are not managed properly. Not destructive since the operation is reversible.

Verdict

git_stash Rate-limited

git_stash 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.
