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.

Frequently asked questions

What tokens and chains are supported?

Solana: USDC, USDT, SOL. Base: USDC, USDT, ETH, WETH. Bridging is available between Solana and Base.

What are the fees for using Clawswap?

Solana → Base costs $0.50 USDC (paid automatically via x402, gas sponsored by ClawSwap). Base → Solana is free (agent pays ~$0.001 Base gas directly).

What private keys do I need to configure?

`SOLANA_PRIVATE_KEY` (base58) is needed for Solana→Base transfers. `BASE_PRIVATE_KEY` (0x-prefixed hex) is needed for Base→Solana transfers. Only keys for the directions you plan to use are required.

How do I check the status of a bridge?

Use the `clawswap_status` tool with the `requestId` returned by a previous `clawswap_bridge` call.

What is the difference between `clawswap_bridge` and `clawswap_quote`?

`clawswap_quote` previews a bridge without executing it (free, no payment), while `clawswap_bridge` performs the actual transfer, including payment and settlement.
