tools: []
notes: Zeller's developer portal (Redocly Realm) ships a hosted MCP server whose purpose is documentation
  search over the gated reference docs, surfaced via config flag mcpData.docs.enabled. It is NOT a set
  of tools bound to the payments API. The live tools/list manifest requires an authenticated OAuth session
  (dynamic client registration is supported), so tool input schemas cannot be captured anonymously. No
  public OpenAPI exists to bind tools against, so no tool-crosswalk is emitted.
deployment:
  mode: none
  endpoint: https://developer.myzeller.com/_mcp
  verified: probed
  probe: dead
  note: the endpoint this manifest claimed did not answer; recorded as none rather than deleted so the
    claim stays auditable
