Crypto Toolkit MCP server

mcp-crypto-toolkit

Live crypto prices, conversion, gas tracker, portfolio tools, and calculators for AI agents.

Ask Claude: What's ETH doing? Top 10 coins? Gas on Base? What's my portfolio worth?

Hosted (Claude.ai Custom Connector): https://mcp-crypto-toolkit.nad33mahm3d.workers.dev/mcp Docs: DeepWiki · mcpservers.org

Quick Install

npx -y mcp-crypto-toolkit

Installation

Claude Desktop / Cursor / Windsurf

{
  "mcpServers": {
    "crypto-toolkit": {
      "command": "npx",
      "args": ["-y", "mcp-crypto-toolkit"]
    }
  }
}

Local build:

{
  "mcpServers": {
    "crypto-toolkit": {
      "command": "node",
      "args": ["/ABSOLUTE/PATH/TO/mcp-crypto-toolkit/dist/index.js"]
    }
  }
}

HTTP server

npm run build
npm run start:http
# POST http://localhost:3000/mcp

Deploy (Smithery / remote MCP) — optional

You do not need paid hosting for discoverability. This server already installs via npx -y mcp-crypto-toolkit (stdio) and is listed on the Official MCP Registry. Glama and PulseMCP ingest from there — no Fly/Railway bill required.

Only deploy HTTP if you want a remote /mcp endpoint (e.g. Claude.ai Custom Connector or Smithery URL publish).

Claude.ai Custom Connector

Public hosted endpoint (Cloudflare Workers):

https://mcp-crypto-toolkit.nad33mahm3d.workers.dev/mcp

1. In Claude.ai: Settings → Connectors → Add custom connector
2. Paste the URL above (must include /mcp)
3. You should see 10 tools (get price, convert, trending, …)

Or deploy your own (Cloudflare / Docker / Render) and use https://YOUR-HOST/mcp. After upgrading a hosted server, remove and re-add the connector if tools still show as empty.

Do not put a remote URL in claudedesktopconfig.json — that file is stdio-only. For Claude Desktop local use, prefer:

{
  "mcpServers": {
    "crypto-toolkit": {
      "command": "npx",
      "args": ["-y", "mcp-crypto-toolkit"]
    }
  }
}
