unwatch_repo · TempoGraph MCP: Risk & Policy

WHAT IT DOES

What unwatch_repo does on TempoGraph

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

WHY IT NEEDS A POLICY

Why unwatch_repo needs a policy

This tool modifies the state of a repository watcher by deactivating it. It does not delete data permanently, but it does change a persistent configuration (watching vs. not watching). This is a reversible state change (watching can be re-enabled), so Write is the appropriate category rather than Destructive.

From the tool's definition 'Stop watching a repository for file changes' — disables an active watch/subscription on a repo

Verdict

unwatch_repo Rate-limited

unwatch_repo 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.
