WHAT IT DOES

What update_rate_limit does on Portkey Admin

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

RISK

Why update_rate_limit is rated Medium

The tool modifies (updates) rate limit configurations, which is a Write operation. The severity is medium because misconfigured rate limits could disrupt service availability or security posture, but the change is reversible. High confidence due to clear indication of modification intent, though the description lacks detail about scope and potential business impact.

From the tool's definition Tool name 'update_rate_limit' and description 'Update a rate limit' indicate modification of existing configuration data. This is a reversible change to rate limiting settings.

RECOMMENDED RULE

The rule that runs update_rate_limit safely

update_rate_limit Rate-limited

update_rate_limit 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.
