notes: Official Newline MCP server exposing the Newline Banking API to AI agents. Distributed from the
  newline53 GitHub org and run locally over stdio via npx. 34 tools cover customers, products, pools,
  synthetic/custodial accounts and line items, transfers, combined transfers, transactions and events,
  returns, and virtual reference numbers. The surface is read-heavy (list/get) plus three write tools
  (create-newline-transfer, create-synthetic-account, delete-synthetic-accounts). Live tools/list requires
  the stdio server with HMAC credentials; tool names below are read verbatim from the server source.
