# Sync the signed-in user and return their organizations

> The first call a new session makes. Supabase owns the account; this creates the mirror row on first sight and answers with the organizations the user belongs to, so the app can decide between onboarding and a dashboard in one round trip instead of three.

    **The API is the product.** The dashboard is one client and the MCP server
    at `/mcp` is another. If a number needs deriving, a service derives it —
    never a React component, or the two clients drift.


    **Two kinds of auth.** The dashboard sends a Supabase access token as a
    Bearer JWT. MCP agents send `X-API-Key`, and the organization is resolved
    from the key.


    **Two data modes.** SERP results and Google Trends are fetched live on
    request. Everything else is written by the worker and read from Postgres, so
    a freshly-created project returns empty until its jobs complete.
