# brc_create_purchase Creates a BRC purchase using structured MCP fields. Requires a reference when the company is configured for manual purchase references; otherwise prefer brc_create_purchase_gen_ref. Requires routeToken from brc_route_request for the matching action workflow. Call brc_route_request first with the user's complete original action request. Retain the returned routeToken through lookup, preview, and confirmation, and pass the same token on the final permitted transactional tool call. Never invent a placeholder token. A routeToken is not permission to post — preview-before-posting and confirmWrite/confirmDelete still apply. Also requires confirmCounterpartyExplicit: true once the user has explicitly named or confirmed the customer/supplier in the current conversation. Do not reuse a counterparty from an earlier preview without that confirmation. Agent View of the PolicyLayer registry record for `brc_create_purchase`.
