How purchases work

1. Claude finds the product and shows you the details

2. Claude requests wallet approval via request_payment — a signing prompt goes to your connected wallet (powered by @wyntraxyz/mcp-wallet)

3. Once you approve, the transaction is submitted on-chain

4. Claude registers the purchase and confirms it on-chain

5. Your download link is ready instantly once confirmed

Confirmations typically take 15–60 seconds depending on the network.

Available tools

Supported blockchains

• Ethereum

• Base

• Robinhood — pay with ETH or USDG (Robinhood's stablecoin — USDC is not used there)

• Solana

Architecture

• src/index.js — stdio MCP entrypoint (local/dev use with Claude Desktop)

• src/index.http.js — StreamableHTTP MCP entrypoint, deployed behind mcp.wyntrax.xyz

• src/wyntrax-client.js — REST client for the Wyntrax app's /api/mcp/v1/* routes

• src/wallet-bridge.js — wraps @wyntraxyz/mcp-wallet to request wallet signatures for payments, with on-chain verification (createEvmVerifier/createSolanaVerifier) so a payment can't be marked confirmed without a real, matching transaction

• src/chain-clients.js — shared viem (EVM) and @solana/web3.js (Solana) read clients, used by the payment verifier above and by OAuth login-signature verification

• src/oauth/* — OAuth 2.0 authorization server (PKCE, dynamic client registration) with wallet-signature login rendered via @wyntraxyz/mcp-wallet-ui

• src/tools.js — the MCP tool definitions Claude calls

In production, mcp.wyntrax.xyz is served by the main Wyntrax Next.js app, which rewrites requests to this server (MCP_INTERNAL_URL) and forwards an already-verified X-User-Id header — see src/oauth/middleware.js. This server also works standalone (its own OAuth + bearer-token validation) for local development.

Wallet packages

The OAuth wallet-connect/login page (GET /oauth/authorize) is separate from all of the above — it's hand-rolled HTML in src/oauth/routes.js, since there's no prebuilt "connect + sign in" UI in @wyntraxyz/mcp-wallet-ui (its <WalletApproval /> is specifically for approving one pending payment request, not for logging in). Signature verification for login uses viem (EVM) and tweetnacl/bs58 (Solana) directly.
