WHAT IT DOES

What invite_member does on Businys

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

RISK

Why invite_member is rated Medium

This tool writes data (invitation record created, email sent) and has a reversible effect (invitations can typically be cancelled or ignored). It is not destructive because the invitation does not immediately or irreversibly alter existing data.

From the tool's definition Tool description states 'Send an email invitation to join the organization' — this creates a new invitation record and triggers an email action, modifying organizational membership state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs invite_member safely

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

invite_member Rate-limited

invite_member 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.
