Luzia

@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

• A Luzia API key (get one here)

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

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 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: 25 requests/minute, 1,000/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).
