SwapChan

Best-price same-chain and cross-chain crypto swap routing — as an MCP server, with an anime cast. 🎌

SwapChan fans out a single swap request to 0x, CoW, LI.FI, Across and Relay at once, ranks every route by net USD after gas and fees, and returns an unsigned transaction for the winner. It never holds keys and never signs or broadcasts — your wallet does. 12 networks, same-chain and cross-chain.

Your agent asks in plain English → SwapChan fans out to every router, ranks by net USD after gas, and hands back an unsigned transaction. Your wallet signs.

Use it as an MCP server

Hosted, keyless, zero setup:

claude mcp add --transport http swapchan https://mcp.swapchan.com/mcp

Any MCP client, via stdio bridge:

{
  "mcpServers": {
    "swapchan": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.swapchan.com/mcp"]
    }
  }
}
Earn 5 bp as an agent builder

Register a partner id with your payout address and pass partner to get_quote / compare_routes (REST: &partner=<id>). You earn half of SwapChan's 0.1% fee on every swap with a verified fee:

curl -X POST https://api.swapchan.com/partners -H 'content-type: application/json' \
  -d '{"name":"My Agent","siteUrl":"https://github.com/me/my-agent","evmAddress":"0xYourPayoutAddress"}'

Returns id, a private dashboard token and dashboardUrl. Sites can embed the widget or use ?ref=<id> links. Details: swapchan.com/partners.

Open by design

SwapChan's MCP server is keyless on purpose. It's per-IP rate-limited, slippage-capped, and build_swap_tx only ever returns an unsigned transaction — the server has no keys, never signs, and never moves funds. Try it with zero setup.
