ops_access_approve · Slack Max API MCP: Risk & Policy

WHAT IT DOES

What ops_access_approve does on Slack Max API MCP

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

WHY IT NEEDS A POLICY

Why ops_access_approve needs a policy

This tool modifies workspace access permissions by converting a pending request into an active grant. While it affects authorization and could have downstream consequences if misused (an AI agent could approve requests for itself or untrusted parties), the operation itself is reversible via ops_access_revoke and does not delete data or execute arbitrary code. It is therefore Write rather than Execute or Destructive.

From the tool's definition Tool description states it 'Approve[s] a pending access elevation request and convert[s] it into an active time-boxed grant' — this creates/modifies an access control grant in the Slack workspace, which is a reversible state change (the grant can be revoked).

ops_access_approve Rate-limited

ops_access_approve 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.
