abort_staged · Fs Git MCP: Risk & Policy

WHAT IT DOES

What abort_staged does on Fs Git

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

WHY IT NEEDS A POLICY

Why abort_staged needs a policy

Aborting a staged session reverses in-progress changes by discarding uncommitted staged work, making it a Write operation rather than Destructive because the underlying committed repository state remains intact. It is reversible in that one can re-stage work.

From the tool's definition Tool name 'abort_staged' and description 'Abort a staged session' indicate the tool cancels or discards a staged branching session, which modifies the state of the repository's staged operations.

abort_staged Rate-limited

abort_staged 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.
