WHAT IT DOES

What crow_generate_invite does on Crow

AI agents use crow_generate_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_generate_invite is rated Medium

This tool creates a new, reversible resource (an invite code) in the system. It does not read sensitive data, execute arbitrary code, delete anything, or involve financial transactions. The blast radius is minimal—a generated invite code is a standard access control mechanism that can be revoked or allowed to expire naturally (within 24 hours as specified).

From the tool's definition Tool 'crow_generate_invite' generates and creates a single-use invite code for sharing. The description explicitly states the code is generated and can be shared, indicating it creates data (the invite code) in the system.

Attacks that exploit this kind of access

crow_generate_invite Rate-limited

crow_generate_invite 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.
