Dexter MCP

What it does

Dexter MCP is a production-ready MCP server for Solana DeFi, exposing 60+ tools across two access tiers. The public OpenDexter endpoint (open.dexter.cash/mcp) requires no auth and uses ephemeral session wallets for x402 micropayments. The authenticated Dexter MCP (mcp.dexter.cash/mcp) offers full OAuth2/OIDC login with managed wallet infrastructure, member trading surfaces, and Pro-gated Hyperliquid tools.

It ships rich interactive UI components (built with the @modelcontextprotocol/ext-apps SDK) that render directly inside supported MCP clients — OHLCV price charts, Solana swap previews and execute flows, portfolio dashboards, live pump stream feeds, wallet resolution cards, reputation badges, and more.

Key features

• Rich UI apps — 20+ HTML UI templates including OHLCV charts, swap previews, pumpstream feeds, portfolio views, and Hyperliquid positions rendered inline inside MCP clients
• 60+ Solana DeFi tools — wallet resolution, token lookups, Birdeye OHLCV data, Jupiter swap quotes and execution, Hyperliquid perpetuals, onchain activity analytics
• x402 micropayments — AI agents can discover, price-check, and pay x402 APIs natively via x402_search, x402_fetch, x402_wallet, and x402_pay
• Dual transport — HTTPS SSE for Claude/ChatGPT connectors; stdio bridge for Codex, Cursor, and local agents
• Tiered access — guest (read-only research), member (personal wallet + trading), pro (Hyperliquid), dev (Codex bridge)
