WHAT IT DOES

What create_invites_bulk does on TrekMail MCP Server

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

RISK

Why create_invites_bulk is rated Medium

This tool creates new invitation records in bulk (Write category) but does not execute arbitrary code, delete data irreversibly, or move money. The blast radius is medium because bulk invitation creation could be misused to spam users or create unauthorized invites across domains if an agent sends invites to unintended recipients or domains, but the action is reversible (invites can typically be revoked or expire).

From the tool's definition Tool description states it 'Create[s] multiple setup invites' and 'Returns results for each item', indicating creation of email invitation records.

create_invites_bulk Rate-limited

create_invites_bulk 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.
