note: Mambu publishes an official MCP server, MMCP (mambu-gmbh), a Model Context Protocol server that
  lets AI agents discover and execute REST API operations described by OpenAPI specifications. It ships
  with a complete catalog for the Mambu Banking Platform V2 API. Distributed as a Homebrew tap; runs in
  stdio mode by default (subprocess over stdin/stdout, works with Claude Desktop, Claude Code, Junie CLI
  and other MCP clients) with an optional standalone HTTP server mode. Rather than one tool per operation,
  MMCP exposes two generic tools (search + invoke) that operate over the bundled Mambu V2 catalog.
