RISK

Why create_person is rated Medium

This tool creates new records in the CRM (people/contacts), which is a reversible write operation. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read data (Read).

From the tool's definition Tool name 'create_person' and description 'Create a new person in Twenty CRM' indicate data creation. The verb 'create' and 'new' confirm this is a write operation that adds a record to the CRM system.

RECOMMENDED RULE

The rule that runs create_person safely

create_person Rate-limited

create_person 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.
