  Lucid publishes TWO distinct remote MCP servers. The product server (mcp.lucid.app) is
  OAuth-gated and its tools/list could not be enumerated anonymously; the developer-documentation
  server (lucid-developer-docs.readme.io) is anonymous and its real tool set — including
  inputSchema per tool — was captured verbatim to lucid-docs-mcp-tools.json.

    note: >-
      tools/list requires an authenticated OAuth token, so the live tool schemas were not
      captured. Lucid's own description of the surface (blog + docs): search, retrieve, edit,
      summarize and create Lucid documents from an AI client. Do not treat that prose as a
      tool manifest — the authoritative schemas require authenticated introspection.
  clients:
  - ChatGPT (connector)
  - Claude (connector)
  - Microsoft Copilot
  - Cursor
  - Microsoft Power Platform connector (learn.microsoft.com/connectors/lucidmcpserver)

  - Lucid SCIM API
  provenance_note: >-
    This server is what produced openapi/lucid-rest-api-openapi.yml,
    openapi/lucid-data-api-openapi.yml and openapi/lucid-scim-api-openapi.yml — each operation
    was read back verbatim from Lucid's uploaded specs via get-endpoint.
