rotate_webhook_secret · Run402 MCP: Risk & Policy

WHAT IT DOES

What rotate_webhook_secret does on Run402

AI agents use rotate_webhook_secret to create or update resources in Run402 — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Run402 environment.

WHY IT NEEDS A POLICY

Why rotate_webhook_secret needs a policy

Rotating a webhook secret generates a new cryptographic key and invalidates the old one. This is a Write operation (creates new secret, modifies configuration), though it has a semi-destructive side effect in that any integrations using the old secret will break. It does not delete data irreversibly in the traditional sense, but it does replace credentials.

rotate_webhook_secret Rate-limited

rotate_webhook_secret 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.
