WHAT IT DOES

What crow_room_invite does on Crow

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

RISK

Why crow_room_invite is rated Medium

The tool creates new artifacts (room tokens, encrypted invites) and modifies the state of contacts by sending them notifications and join links. This is a reversible write operation (invites can be revoked or ignored). It does not execute arbitrary code, delete data, move money, or read existing data without side effects.

From the tool's definition Tool description states it 'Generates a room token and sends an encrypted invite', which are creation and modification operations that create new invitations and room associations.
