Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "clawswap": {
      "command": "npx",
      "args": [
        "-y",
        "@clawswap/mcp-server"
      ],
      "env": {
        "SOLANA_PRIVATE_KEY": "your-value",
        "BASE_PRIVATE_KEY": "your-value",
        "SOLANA_RPC_URL": "your-value",
        "BASE_RPC_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add clawswap --env SOLANA_PRIVATE_KEY=your-value --env BASE_PRIVATE_KEY=your-value --env SOLANA_RPC_URL=your-value --env BASE_RPC_URL=your-value -- npx -y @clawswap/mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "clawswap": {
      "command": "npx",
      "args": [
        "-y",

        "BASE_RPC_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "clawswap": {

Common questions

Is Clawswap safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SOLANA_PRIVATE_KEY, BASE_PRIVATE_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.5) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@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.

Installation

Claude Desktop

Add to your claude_desktop_config.json:

"mcpServers": { "clawswap": { "command": "npx", "args": ["-y", "@clawswap/mcp-server"], "env": { "SOLANA_PRIVATE_KEY": "your-base58-solana-private-key", "BASE_PRIVATE_KEY": "0x-your-hex-base-private-key" } } } }

Claude Code

claude mcp add clawswap -- npx -y @clawswap/mcp-server

Then set environment variables:

export SOLANA_PRIVATE_KEY="your-base58-solana-private-key"

export BASE_PRIVATE_KEY="0x-your-hex-base-private-key"

Cursor

Add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

OpenAI Codex

codex mcp add clawswap -- npx -y @clawswap/mcp-server

Or add to ~/.codex/config.toml:

[mcp_servers.clawswap]

command = "npx" args = ["-y", "@clawswap/mcp-server"] env = { SOLANA_PRIVATE_KEY = "your-base58-solana-private-key", BASE_PRIVATE_KEY = "0x-your-hex-base-private-key" }
