What is the HHS Open Payments MCP Server?
Connect to the HHS Open Payments database to explore financial transparency in healthcare. This server allows you to query datasets, search for specific physicians or teaching hospitals, and analyze payments made by drug and device companies.
What you can do
- Dataset Discovery — List all available Open Payments datasets and inspect their metadata, including column definitions and update timestamps.
- Physician & Hospital Search — Search for specific healthcare providers or teaching hospitals by name to find their associated records.
- Advanced Querying — Use Socrata Query Language (SoQL) to filter, sort, and limit data for precise financial analysis.
- Data Export — Download specific datasets in CSV, JSON, or XML formats for external processing or reporting.
- Metadata Inspection — Fetch detailed information about specific datasets to understand the underlying data structure.
How it works
- Subscribe to this server
- Enter your HHS/Socrata API Key (optional but recommended for higher rate limits)
- Start auditing healthcare financial data directly from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Researchers & Journalists — Uncover financial ties between the medical industry and healthcare professionals for investigative reporting.
- Compliance Officers — Monitor and verify the accuracy of reported financial transfers within healthcare organizations.
- Healthcare Consumers — Check for potential conflicts of interest or financial relationships of their medical providers.

Frequently asked questions
Can I search for a specific doctor by name to see their financial records?
Yes! Use the search_physicians tool with the doctor's name. The agent will return matching profiles and their associated payment data from the Open Payments database.
How do I filter data for a specific state or payment amount?
You can use the query_dataset tool and provide a SoQL filter in the where parameter (e.g., recipient_state = 'NY' or total_amount_of_payment_usdollars > 1000).
What formats can I use to download the datasets?
The download_dataset tool supports 'csv', 'json', and 'xml' formats. JSON is generally recommended for programmatic access and AI analysis.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
