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.

get_solana_asset_balances reads the bound wallet's configured famous-token list and returns a USD quote for each. The included list covers SOL, USDC, USDT, wSOL, JUP, JTO, PYTH, RAY, WIF, and BONK. Edit config/solana-famous-tokens.json to choose the queried assets; each item requires symbol, name, mint (use null for SOL), and coingeckoId. Set SOLANA_RPC_URL to a production RPC provider endpoint to avoid public-RPC rate limits; when omitted, it uses Solana's public mainnet endpoint. Prices are fetched from CoinGecko and are indicative only.

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.
