    Self-hosted, so no public discovery document exists to probe. Recorded from Plotly's own
    documentation.
app_level_auth:
  note: >-
    Distinct from provider authentication: Plotly ships auth libraries its customers embed in
    their own Dash apps - dash-auth (basic auth and Plotly authentication) and
    dash-enterprise-auth. Dash MCP servers running inside a customer app either inherit Plotly
    Cloud authentication or implement the standard OAuth 2.0 flow from the MCP specification
    (https://dash.plotly.com/dash-mcp/auth).
