ChatGPT / Custom GPTs

ChatGPT doesn't support MCP natively. Use the REST API directly instead.

Same data, different interface

The REST API gives you access to the same 1,600+ tests. You just call HTTP endpoints instead of MCP tools.

Base URL & Headers

Base URL: https://nlnbbquyqrbkgaitbbgk.supabase.co

Include these headers with every request:

apikey: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJzdXBhYmFzZSIsInJlZiI6Im5sbmJicXV5cXJia2dhaXRiYmdrIiwicm9sZSI6ImFub24iLCJpYXQiOjE3NzE2NzcxODMsImV4cCI6MjA4NzI1MzE4M30.Kf_4ci_NVx6m8KCLnEP7Gj_GoygZ-PKbK1mHmITq77M
Authorization: Bearer <same key as above>

For Custom GPTs
