WHAT IT DOES

What crow_generate_short_invite does on Crow

AI agents use crow_generate_short_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_short_invite is rated Medium

This tool creates (writes) a new, reversible artifact—a time-limited pairing code—without executing operations or making irreversible changes. The code is transient and does not modify core data. While it facilitates access delegation, the creation of the code itself is a write operation with minimal blast radius since the code expires quickly and requires out-of-band communication to be used.

From the tool's definition Tool description explicitly states it 'Generate[s] a short 12-character pairing code' with specified expiration (10 minutes), creating a temporary credential/token for access sharing.

RECOMMENDED RULE

The rule that runs crow_generate_short_invite safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Crow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For crow_generate_short_invite, this is the rule to start with:

crow_generate_short_invite Rate-limited

crow_generate_short_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.
