source: No Diebold Nixdorf MCP server exists. Searched the web, the SwaggerHub organization Diebold-Nixdorf, github.com/DieboldNixdorf,
  npm and PyPI, and probed /.well-known/ on every Diebold Nixdorf host this record knows. The tool list below is
  DERIVED from operations in openapi/ and is not published by the provider.
deployment:
  mode: none
  endpoint: null
  install: null
  package: null
  auth: unknown
  verified: derived
deployment_note: 'mode: none. Nobody ships a server — not a hosted endpoint and not a stdio package. No endpoint
  URL is recorded because guessing one would read as a verified agent surface. Note also that the underlying product
  is customer-deployed: any future MCP server for these APIs would have to point at a financial institution''s own
  Vynamic Transaction Middleware installation, not at a Diebold Nixdorf host.'

caution: 'These are candidates only. Every one of them touches money movement on a live core banking system, and
  the contract documents replay protection on exactly two operations (see conventions/diebold-conventions.yml idempotency.coverage:
  partial) and no reversal window at all. An agent surface over this API would need both before it was safe to build.'
