WHAT IT DOES

What create_buyer_group does on Starfield

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

Parameter	Type	Required	Description
`name`	string	Yes
`dryRun`	boolean	—	Defaults to true. Returns a preview of the exact call instead of performing it. Set false to execute.
`reason`	string	—	Required for a live write. Recorded as the audit reason (X-Adrata-Reason).
`approved`	boolean	—	Required (true) for a live write. Records that the caller confirmed the mutation; it does not by itself grant scope.
`companyId`	string	Yes
`idempotencyKey`	string	—	Required for a live write. Sent as Idempotency-Key so a retry cannot double-apply.

Parameters from the server's own tool schema.

RISK

Why create_buyer_group is rated Medium

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

RECOMMENDED RULE

The rule that runs create_buyer_group safely

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

create_buyer_group Rate-limited

create_buyer_group 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.
