WHAT IT DOES

What invite_portal_user does on QuintaDB

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

Parameter	Type	Required	Description
`email`	string	Yes	Email юзера
`login`	string	—	Логін (якщо не вказано — використовується email)
`app_id`	string	Yes	Project ID (from list_projects)
`portal_id`	string	Yes	Portal ID (from list_portals or describe_project)
`send_email`	boolean	—	Mail the portal's invitation letter (default true). false: nobody is told a password — the person sets their own from the portal's sign-in page.

Parameters from the server's own tool schema.

RISK

Why invite_portal_user is rated Medium

An AI agent can call invite_portal_user faster than any human can review: one bad instruction and it creates or modifies resources in QuintaDB by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs invite_portal_user safely

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

invite_portal_user Rate-limited

invite_portal_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.

FAQ

Questions about invite_portal_user

What does the invite_portal_user tool do? +

Invite a new person into a portal: creates their account and mails the portal's invitation letter. The new account gets a password of its own, which only the invitation letter shows (with a one-time link that signs the person in); the answer's invitation says what was mailed. Never tell anyone a password. It is categorised as a Write tool in the QuintaDB MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does invite_portal_user accept? +

invite_portal_user accepts 5 parameters: email, login, app_id, portal_id, send_email. Required: email, app_id, portal_id. The full parameter table on this page comes from the server's own tool schema.
