Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

MCP server for cryptocurrency pricing data - access real-time ticker prices, exchanges, and markets from AI assistants

Readme

@luziadev/mcp-server

npm version License: MIT

Model Context Protocol (MCP) server for cryptocurrency pricing data. Gives AI assistants like Claude real-time access to ticker prices, exchange information, and OHLCV history from the Luzia API.

Features

  • Real-time ticker prices from multiple exchanges (Binance, Coinbase, Kraken, OKX, Bybit)
  • Historical OHLCV candlestick data for technical analysis
  • Market information and trading pairs
  • Exchange status and availability

Requirements

Remote connection (recommended)

The fastest way to use Luzia with your AI assistant is to connect to our hosted MCP server at https://mcp.luzia.dev/mcp. No install required. Just paste the URL and your API key.

Claude.ai web / Anthropic console

Settings → Integrations → Add custom MCP:

  • URL: https://mcp.luzia.dev/mcp
  • Authentication: Bearer token — paste your API key (lz_...)

Claude Desktop (via mcp-remote)

Claude Desktop's native remote MCP support is still rolling out, so the easiest path today is the mcp-remote shim, which bridges a remote HTTP MCP to Claude Desktop's stdio interface.

Edit your config:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "luzia": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.luzia.dev/mcp",
        "--header",
        "Authorization:Bearer lz_your_api_key"
      ]
    }
  }
}

Restart Claude Desktop (Cmd+Q on macOS) and start asking questions.

VS Code, Cursor, Cline, Continue.dev

Paste the URL and Authorization header into the MCP settings for your tool:

  • URL: https://mcp.luzia.dev/mcp
  • Header: Authorization: Bearer lz_your_api_key

MCP Inspector

npx @modelcontextprotocol/inspector

Then point the inspector at https://mcp.luzia.dev/mcp and add the Authorization: Bearer lz_... header.

Local install (advanced)

Prefer running the server locally? @luziadev/mcp-server still ships on npm and runs over stdio.

# Run directly with npx (no install needed)
LUZIA_API_KEY=lz_your_api_key npx -y @luziadev/mcp-server --stdio

Claude Desktop config (local stdio)

{
  "mcpServers": {
    "luzia": {
      "command": "npx",
      "args": ["-y", "@luziadev/mcp-server", "--stdio"],
      "env": {
        "LUZIA_API_KEY": "lz_your_api_key"
      }
    }
  }
}

Claude Code config (local stdio)

Add to .claude/settings.json:

{
  "mcpServers": {
    "luzia": {
      "command": "npx",
      "args": ["-y", "@luziadev/mcp-server", "--stdio"],
      "env": {
        "LUZIA_API_KEY": "lz_your_api_key"
      }
    }
  }
}

Available Tools

| Tool | Description | |------|-------------| | get_ticker | Get current price for a specific trading pair | | get_tickers | Get prices for multiple pairs or all pairs on an exchange | | get_history | Get historical OHLCV candlestick data for a trading pair | | get_exchanges | List supported exchanges and their status | | get_markets | List available trading pairs on an exchange |

Available Prompts

Prompts are pre-built analysis templates that fetch data and generate structured insights. They are available in clients that support MCP prompts (e.g., Claude Desktop via the / menu).

Note: Claude Code does not support MCP prompts directly — use natural language instead (e.g., "Analyze BTC/USDT price movement on Binance") and it will call the underlying tools automatically.

| Prompt | Description | |--------|-------------| | analyze_price_movement | Analyze price movements and trends for a trading pair | | analyze_ohlcv | Analyze OHLCV candlestick data with technical analysis | | compare_exchanges | Compare prices across exchanges for arbitrage opportunities |

Prompt Examples

analyze_price_movement

Fetches current ticker data and analyzes bid-ask spread, 24h stats, and volume.

Arguments:

  • exchange (required): e.g., "binance", "coinbase"
  • symbol (required): e.g., "BTC/USDT", "ETH/USD"

Claude Desktop: Type / → select analyze_price_movement → fill in exchange: binance, symbol: BTC/USDT

Natural language (any client): "Analyze the current BTC/USDT price movement on Binance"

analyze_ohlcv

Fetches historical candlestick data and requests technical analysis including trends, support/resistance, volume patterns, and candlestick patterns.

Arguments:

  • exchange (required): e.g., "binance"
  • symbol (required): e.g., "BTC/USDT"
  • interval (optional): "1m", "5m", "15m", "1h", "1d" (default: "1h")
  • period (optional): e.g., "24h", "7d", "30d" (default: "24h")

Claude Desktop: Type / → select analyze_ohlcv → fill in exchange: binance, symbol: BTC/USDT, interval: 1h

Natural language (any client): "Analyze BTC/USDT OHLCV candles on Binance with 1h interval for the last 7 days"

compare_exchanges

Fetches ticker data from multiple exchanges and compares prices, spreads, and liquidity for arbitrage analysis.

Arguments:

  • symbol (required): e.g., "BTC/USDT"
  • exchanges (optional): comma-separated list, e.g., "binance,coinbase,kraken" (default: "binance,coinbase,kraken")

Claude Desktop: Type / → select compare_exchanges → fill in symbol: BTC/USDT

Natural language (any client): "Compare BTC/USDT prices across all exchanges"

Rate Limits

Inherits from your Luzia subscription tier:

  • Free: 100 requests/minute, 5,000/day
  • Pro: 1,000 requests/minute, 20,000/day

Troubleshooting

"Unauthorized" errors

  • Remote: verify your Authorization: Bearer lz_... header is set and the key starts with lz_.
  • Stdio: verify LUZIA_API_KEY is set in your MCP client config and that the key has not been revoked.

Remote session errors

  • If your client reports "Unknown session id", the server was restarted or your session expired (30min idle). Reconnect and the client will re-initialize automatically.

Claude Desktop can't find the server (stdio)

  • Verify claude_desktop_config.json is valid JSON.
  • Ensure Node.js 20+ is installed (node --version).
  • Restart Claude Desktop completely (Cmd+Q on macOS).
