Optional settings from the registry entry, left out of the block above: GROUPON_SESSION_COOKIE (Optional, and only for the cart tools. Leave unset to have the ContextMint Bridge browser extension pick up your signed-in groupon.com session. Otherwise paste the full Cookie request header from a signed-in www.groupon.com /mobilenextapi/graphql request (DevTools → Network). It authorizes changes to your Groupon cart, so treat it like a password), GROUPON_DISABLE_FETCHPROXY (Set to 1/true to disable the fetchproxy browser-bridge fallback (then the cart path relies solely on GROUPON_SESSION_COOKIE)), GROUPON_GRAPHQL_URL (Override the GraphQL endpoint (defaults to https://www.groupon.com/mobilenextapi/graphql). The cart tools send your session cookie, so they refuse any override that is not an https://*.groupon.com URL), GROUPON_CACHE_TTL (Response-cache TTL for reads in seconds (0 = off; default 60)), FETCHPROXY_WS_PORT (Localhost port of the fetchproxy concentrator the ContextMint Bridge extension connects to (default 37149). Every MCP on one machine shares it, so move it for all of them or not at all), FETCHPROXY_WS_HOST (Bind interface for the fetchproxy concentrator, a literal IP only (default 127.0.0.1). Keep on loopback; it exists for hosted deployments that run each MCP in its own network namespace), FETCHPROXY_IDENTITY_DIR (Absolute path where the fetchproxy long-term identity keypair is stored (default ~/.fetchproxy/identity/)).
