Product model

1. Sign in with GitHub or Google.
2. Create a private MCP endpoint at /api/mcp (or a custom subdomain at the edge).
3. Connect that endpoint from Claude, ChatGPT, or Grok.
4. Bind an optional Solana wallet with a signed challenge.
5. Publish pages or upload content through MCP tools.

Vercel setup

Create GitHub and Google OAuth clients, then add the variables in .env.example. The production callback URLs are https://mcpbuddy.creatorsand.fun/api/auth/callback/github and https://mcpbuddy.creatorsand.fun/api/auth/callback/google. Connect both Vercel Postgres and a private Vercel Blob store. Run npm run build before deploying.

Run drizzle/0000_initial.sql once against Vercel Postgres. The unique (kind, jti) constraint gives authorization-code and refresh-token rotation an atomic replay barrier across serverless invocations. Blob is used for publishable file payloads.

Before enabling Google login, run drizzle/0003_auth_identities.sql in the Vercel Postgres SQL editor. It preserves existing GitHub accounts and adds provider-specific identity mapping.
