## What it does

The server connects directly to Costco's internal GraphQL endpoints over HTTP/2. It does not use browser automation at runtime. Available tools return receipt items, coupons, and order statuses. Looked-up products are cached in a local SQLite file at `~/.costco-mcp/products.db`.

Authentication relies on Azure AD B2C refresh tokens extracted from an active session. They remain valid for roughly 90 days. You can extract tokens with `costco-auth-browser` or copy them manually from browser storage. Multi-account setups are supported.

The tool targets unpublished internal endpoints. A backend change on Costco's side can break queries immediately. Tokens are saved in plain text under `~/.costco-mcp/`, so safety depends entirely on your local file permissions.
