FAQ

Questions about brc_create_bank_account

What does the brc_create_bank_account tool do? +

Creates a BRC bank account. Do not call this tool with confirmCreate=true until the user has reviewed a plain-English summary and explicitly confirmed creation. Required fields: acCode, details, lastChq, and nominalAcCode. categoryId is optional; BRC may create the Bank Payments category automatically when categoryId is omitted. nominalAcCode must reference an existing balance-sheet bank nominal account created in BRC setup. 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. It is categorised as a Write tool in the Red by Big Red Cloud MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does brc_create_bank_account accept? +

brc_create_bank_account accepts 12 parameters: acCode, address, balance, details, lastChq, payload, sortCode, categoryId, routeToken, accountName, companyName, accountNumber. Required: routeToken, companyName. The full parameter table on this page comes from the server's own tool schema.
