Overview

What is Clawswap?

Clawswap is an MCP server that enables AI agents to send, swap, and bridge tokens cross-chain between Solana and Base with gasless transactions in one tool call. It handles the entire flow from quote to settlement.

How to use Clawswap?

Install via npx -y @clawswap/mcp-server and configure by setting SOLANA_PRIVATE_KEY and/or BASE_PRIVATE_KEY environment variables. Add to a client’s MCP configuration file (e.g., Claude Desktop, Cursor, Windsurf) or use the provided CLI commands for Claude Code or OpenAI Codex. Then invoke the server’s three tools: clawswap_bridge, clawswap_quote, and clawswap_status.
