blixtworks-mcp

Install

Claude Code:

claude mcp add blixtworks --env BLIXTWORKS_PRIVATE_KEY=0xyourkey -- npx -y blixtworks-mcp

Claude Desktop / any MCP client — add to your config:

{
  "mcpServers": {
    "blixtworks": {
      "command": "npx",
      "args": ["-y", "blixtworks-mcp"],
      "env": { "BLIXTWORKS_PRIVATE_KEY": "0xyour-wallet-key" }
    }
  }
}

Paying

Set BLIXTWORKS_PRIVATE_KEY to a wallet private key holding a small amount of USDC on Base. Payment happens automatically per request — no invoices, no subscription.

Use a dedicated low-balance wallet, not your main one. Without a key the server still runs; blixtworks_status works and paid tools return setup instructions instead.

Optional: BLIXTWORKS_URL to point at a different deployment.
