Keys

Never more than its person can do

A request on a key runs as the person who made it, with the same database rules as the browser. Your business admin sets what keys may do in Settings, API and agents.

Read, or read and change
Which areas a key covers, and whether it may delete
An expiry on every key
Admins can see and revoke every key in the business

MCP tool	REST	What it does
search	GET /search?q=	Leads, people and vehicles at once
list_records	GET /{resource}	Filters, search, order and paging
create_records	POST /{resource}	One object, or up to 500
update_records	PATCH /{resource}	Bulk changes, with dry_run first
run_action	POST /actions/{name}	Buy a car into stock, trade sales, documents

REST and MCP

Two front doors, same rules

Both run the same operations, so what works in a script works for an agent. Every change lands in the record’s history under the key’s person.
