[Tool] OnlySwaps MCP Server - Swap crypto with your AI agent

Hey r/ClaudeAI,

Just built an MCP server for OnlySwaps — a no-KYC DEX aggregator that supports 12+ chains.

What it does:

• Get swap quotes (e.g., "How much USDC do I get for 0.1 ETH?")
• Generate swap transactions (ready to sign and broadcast)
• Check transaction status
• Get token prices

Supported chains:
Ethereum, Arbitrum, Base, Optimism, Polygon, Avalanche, BSC, Fantom, Linea, Scroll, zkSync, Mantle

Installation:

// claude_desktop_config.json
{
  "mcpServers": {
    "onlyswaps": {
      "command": "npx",
      "args": ["-y", "@onlyswaps/mcp"]
    }
  }
}

Example usage:

User: "Get me a quote to swap 0.1 ETH to USDC on Arbitrum"
Claude: [uses onlyswaps_get_quote tool]

It's non-custodial — your agent never touches private keys, just generates the transaction data for you to sign.
