What is the Nasdaq Data Link (Quandl) MCP Server?
Connect your Nasdaq Data Link (formerly Quandl) account to any AI agent to access professional-grade financial and economic datasets through natural language.
What you can do
- Datatable Queries — Fetch unsorted data from specific vendors and tables with advanced filtering for tickers, dates, and more
- Metadata Inspection — Retrieve table descriptions, column types, and identify which columns are filterable before running large queries
- Bulk Data Management — Initiate bulk downloads for entire datasets or large slices, returning status updates (PENDING, RUNNING, SUCCEEDED)
- File Retrieval — Download specific bulk files in CSV, Parquet, or ZIP formats once exports are processed
- Pagination & Exporting — Handle large result sets using cursor-based pagination or trigger direct exports for external analysis
How it works
- Subscribe to this server
- Enter your Nasdaq Data Link API Key
- Start querying financial markets from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Financial Analysts — quickly pull historical prices or alternative data without writing complex API scripts
- Data Scientists — explore dataset schemas and initiate bulk exports directly from your research environment
- Quantitative Researchers — automate the retrieval of economic indicators and fundamental data for model inputs

Frequently asked questions
How can I filter a datatable for a specific ticker and date range?
Use the get_datatable tool and provide a JSON string in the filters parameter, such as {"ticker": "AAPL", "date.gt": "2023-01-01"}. This allows you to narrow down results precisely.
How do I check which columns are available in a dataset before querying it?
Run the get_datatable_metadata tool with the vendor_code and table_code. It will return the table's schema, including column names, types, and which fields support filtering.
What should I do if the dataset is too large for a standard query?
For very large datasets, use the request_bulk_download tool. This initiates an asynchronous export process. Once the status reaches 'SUCCEEDED', you can use get_bulk_download_file to retrieve the data.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Nasdaq Data Link (Quandl) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
