Documentation Overview

@clawswap/mcp-server

Send, swap, and bridge tokens cross-chain between Solana and Base — gasless, in one tool call. Built for AI agents using the Model Context Protocol (MCP).

What can it do?

Ask your AI agent any of these:

"Send 10 USDC from Solana to Base"
"How much would it cost to bridge 100 USDC to Base?"
"Transfer my SOL to Base as ETH"
"Swap 50 USDT from Base to Solana"
"Move my stablecoins cross-chain"

The server handles the entire flow: quote → payment → signing → submission → settlement.
