tooling_tokens_rotate · Slack MCP: Risk & Policy

WHAT IT DOES

What tooling_tokens_rotate does on Slack

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

WHY IT NEEDS A POLICY

Why tooling_tokens_rotate needs a policy

Token rotation is a write/modify operation that replaces existing authentication tokens with new ones. This is reversible in the sense that the app can continue to function with new tokens, but misuse could disrupt integrations that depend on existing tokens, causing high-impact service disruptions across all systems using the rotated credentials.

From the tool's definition "Rotate app configuration tokens" - rotating tokens invalidates existing tokens and generates new ones

tooling_tokens_rotate Rate-limited
