WHAT IT DOES

What invite_user does on Kestra Python MCP Server

RISK

Why invite_user is rated Medium

Based on the name alone, 'invite_user' appears to perform user management operations that create or modify access permissions—a classic Write operation. Without a description, confidence is reduced. Severity is medium because inviting users affects access control and could lead to unauthorized access if misused by an agent, but it is reversible (invitations can be revoked).

From the tool's definition Tool named 'invite_user' with no description provided. The name suggests creating or adding a user account/invitation to a system, which is a reversible write operation.

invite_user Rate-limited

invite_user 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.
