A community developed and maintained Model Context Protocol (MCP) server that provides access to Nasdaq Data Link. Built for use with MCP-compatible clients.

This project aims at making easy to access and explore Nasdaq Data Link’s extensive and valuable financial and economic datasets through natural language interfaces and large language models (LLMs).

🐍 This project uses the official nasdaq/data-link-python SDK

🌐 Usage

Nasdaq Data Link MCP - Retail Trading Activity	Nasdaq Data Link MCP - World Bank Data

Once installed and connected to an MCP-compatible client (e.g., Claude Desktop, this server exposes several tools that your AI assistant can use to fetch data.

In this version (0.1.0) the project supports the following databases:

• World Bank dataset on Nasdaq Data Link (freely available for personal use)
• Nasdaq RTAT (preview available for free, full data under subscription)
• Equities 360 (company statistics and fundamental data)

Example conversations might include:

You: What were the most traded stocks by retailers yesterday?
Claude: calls get_rtat(<yetserday>) and returns relevant matches

Or:

You: What was the GDP of Italy in 2022?
Claude: Let me look that up... calls get_indicator_value tool
Claude: The GDP of Italy in 2022 was approximately ... trillion USD.

Or:

You: List all indicators related to CO₂ emissions.
Claude: calls search_worldbank_indicators("CO2") and returns relevant matches

Or:

You: What's the market cap and P/E ratio of Microsoft?
Claude: calls get_stock_stats(symbol="MSFT") and presents the key statistics
