  Derived from the two Clearstream API Playground operations documented verbatim in the
  Clearstream API Developer Guide (August 2025) and confirmed to exist by live 403 probes of
  https://api-t2s-test.clearstream.com/playground on 2026-09-05. No MCP server exists; this is a
  candidate shape only.
description: >-
  Clearstream ships no Model Context Protocol server, hosted or local. Probes of /mcp on
  www.clearstream.com (404), api.clearstream.com (503, host in maintenance) and
  api-t2s-test.clearstream.com (200 HTML catch-all, not an MCP endpoint) found nothing, and no
  Clearstream or Deutsche Börse document mentions MCP. The candidate tools below are derived
  strictly from the only two operations Clearstream publishes the full request shape for; the
  business APIs (SCIM 2.0 user management, CmaX collateral) are known to exist from their scope
  disclosures but their operations and schemas live in the registration-gated Deutsche Börse
  Digital Business Platform catalogue and are NOT guessed here.
deployment:
  mode: none
  endpoint: null
  install: null
  package: null
  auth: oauth
  verified: probed
  note: >-
    auth is recorded as oauth because any future MCP server fronting this API would have to carry
    the platform's OAuth 2.0 password grant AND a mutual-TLS client certificate issued to a named
    Xact user — a materially harder agent story than a bearer key, and worth stating.

known_but_unmapped_surfaces:
  - path_prefix: /scim2
    api: Xact Web Portal User Management (SCIM 2.0)
    scope: scim2-ext-v1
    reason: >-
      Operations and schemas are not public. SCIM 2.0 defines them, but asserting Clearstream's
      operation set from the RFC would be a fabrication.
  - path_prefix: /cmax
    api: CmaX triparty collateral management
    scope: cmax-api
    reason: No public documentation of the REST operations behind this prefix.
