  https://github.com/meetsmore/nittei — README "Overview", crates/api/src/lib.rs
  (utoipa SecurityAddon), crates/api/src/error.rs and examples/jwt.md — fetched 2026-08-25.
  derive-authentication.py was not run: there is no openapi/ document in this repository to
  derive from, because Nittei's OpenAPI is generated at runtime by a self-hosted instance.
note: >-
  The MeetsMore marketplace itself publishes no authentication documentation — its backend
  (api.meetsmore.com) is a closed AWS API Gateway returning 403 "Missing Authentication
  Token" to anonymous callers, with no public developer program, key issuance or docs.
  Everything below describes the Nittei Scheduler API.
apis:
- api: Nittei Scheduler API
  security_schemes:
  - name: api_key
    type: apiKey
    in: header
    parameter: x-api-key
    audience: server-to-server
    description: >-
      The account's secret API key. Registered in the generated OpenAPI document by
      utoipa's SecurityAddon as ApiKey::Header("x-api-key"). Used for every admin-scope
      operation (the *_admin_controller variants). The header name is declared in code as
      NITTEI_X_API_KEY_HEADER and is added to the Axum SetSensitiveHeadersLayer alongside
      Authorization so it is redacted from request logs.

  - name: jwt
    type: http
    scheme: bearer
    bearer_format: JWT
    audience: end-user / browser
    algorithms:
    - RS256
    description: >-
      For browser-to-server calls. The integrating application uploads its RSA public
      signing key once via account.setPublicSigningKey (POST set_account_pub_key), then
      mints a per-user token signed with its private key. RS256 is the only algorithm
      supported. Claims observed in the published example: nitteiUserId (subject), exp,
      iat and schedulerPolicy — an allow/reject list drawn from a Permissions enum,
      e.g. allow [Permissions.All], reject [Permissions.DeleteCalendar].

  - name: nittei-account
    type: apiKey
    in: header
    parameter: nittei-account
    audience: end-user / browser
    description: >-
      Tenant selector that accompanies the JWT. The API returns 401 with
      "Unidentifiable client. Must include the `nittei-account` header" when it is
      missing (NitteiError::UnidentifiableClient in crates/api/src/error.rs).
    source: https://github.com/meetsmore/nittei/blob/master/crates/api/src/error.rs
  authorization_model:
    tenancy: >-
      Account is the multi-tenancy boundary; a User belongs to exactly one Account.
      Admin operations are authenticated by the account API key; end-user operations are
      scoped to the user identified in the JWT.
    permissions: >-
      Per-token allow/reject policy (schedulerPolicy) rather than OAuth scopes. No OAuth
      scope registry is published, so no scopes/ artifact is emitted for this provider.
  outbound_oauth:
    description: >-
      Nittei acts as an OAuth2 client to connect external calendars. Google and Outlook
      credentials are exchanged through user::oauth_integration_controller and
      account::add_account_integration; see IntegrationProvider,
      OAuthIntegrationRequestBody and OAuthOutlookRequestBody in the generated client types.
    providers:
    - Google
    - Outlook
- api: use-ai Server
  security_schemes:
  - name: none-by-default
    type: none
    description: >-
      use-ai-server ships with no authentication of its own; the README's rationale is
      that client-side tools "can already" be invoked by the browser application, so the
      MCP bridge adds no privilege. Authorization for anything the server calls onward is
      forwarded from the client: forwardedPropsProvider supplies an mcpHeaders map keyed
      by picomatch URL patterns, and the server attaches the matching headers only when it
      calls a remote MCP endpoint whose URL matches.

  provider_credentials:
    description: >-
      Model provider keys are server-side environment variables (e.g. ANTHROPIC_API_KEY),
      never sent from the browser.
