Product model
- Sign in with GitHub or Google.
- Create a private MCP endpoint at
/api/mcp(or a custom subdomain at the edge). - Connect that endpoint from Claude, ChatGPT, or Grok.
- Bind an optional Solana wallet with a signed challenge.
- 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.
