# MAIN MCP Server

MCP (Model Context Protocol) server for the MAIN DEX on Base. Provides AI agents (Claude, Cursor, etc.) with tools to interact with the protocol: swap tokens, manage liquidity, enter/exit ALM strategies, and more.

## Connecting to Claude

Claude Code:

```bash
claude mcp add main-mcp --transport http https://api.main.exchange/mcp
```

## MCP Protocol

The server implements [MCP spec 2025-03-26](https://modelcontextprotocol.io) over Streamable HTTP transport.

```bash
# Initialize
curl -s -X POST https://api.main.exchange/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"test","version":"1.0.0"}}}'

# List tools
curl -s -X POST https://api.main.exchange/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' \
  | jq '.result.tools[] | {name, description}'

# Health
curl https://api.main.exchange/mcp/health
```

## x402 Payments

Some tools require USDC payment via the [x402 protocol](https://x402.org). When a paid tool is called without payment, the server responds with a JSON-RPC error containing payment requirements (amount, recipient, network). x402-compatible clients handle this automatically.

**Paid tools**: `createPool`, `launchToken`, `getPoolsTerminal`, `getPoolTerminal`, `getTokenTerminal`, `getTokenHolders`, `getTokenSentiment`, `getForecastSummary`
