tollboothswap-mcp — Token Swaps & Honeypot Checks for AI Agents (MCP Server)

MCP server for Tollbooth: non-custodial token swap execution and token safety screening on 8 chains — Solana, Base, Ethereum, Arbitrum, Polygon, Optimism, BSC, Avalanche. Quotes and symbol resolution are free; swap builds (~$0.005) and safety checks ($0.01) are paid per-call in USDC via the x402 protocol — no API keys, no accounts, no subscriptions.

Quick start

npx tollboothswap-mcp

Claude Desktop / Cursor / any MCP client

{
  "mcpServers": {
    "tollbooth": {
      "command": "npx",
      "args": ["-y", "tollboothswap-mcp"],
      "env": {
        "TOLLBOOTH_PAYER_KEY": "0x<EVM private key holding USDC on Base>"
      }
    }
  }
}

TOLLBOOTHPAYERKEY is optional: without it the free tools (resolvetoken, getquote, getserviceinfo, get_receipt) work fully, and paid tools return x402 payment instructions instead of results. With it, tolls are paid automatically and gaslessly (EIP-3009 — the key never spends gas, only USDC).

Tools

Trust model

Tollbooth is non-custodial: it builds transactions but never holds keys or funds. Your agent signs and submits everything with its own wallet. Every paid build returns a signed receipt for audit trails.
