Compatible with every major AI agent and IDE
What is the HealthData.gov (HHS Open Data) MCP Server?
Connect your AI agent to HealthData.gov, the central clearinghouse for open data from the U.S. Department of Health & Human Services (HHS). This MCP server empowers your agent to discover and analyze vast amounts of public health, social service, and Medicare/Medicaid data.
What you can do
- Catalog Discovery — Search and list thousands of available datasets, views, and resources across the entire HHS ecosystem.
- Deep Data Querying — Use Socrata Query Language (SoQL) to filter, sort, and aggregate data from specific datasets (e.g., hospital capacity, COVID-19 statistics, or provider directories).
- Precision Filtering — Apply complex
$where,$select, and$orderparameters to extract exactly the records you need without downloading massive files. - Real-time Research — Fetch the latest updates on public health metrics directly into your conversation for immediate analysis.
How it works
- Subscribe to this server
- (Optional) Enter your HealthData.gov/Socrata App Token for higher rate limits
- Start querying public health data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Data Scientists & Researchers — quickly prototype data queries and fetch subsets of health data for analysis.
- Public Health Officials — monitor live datasets and trends across different states and regions.
- Developers — integrate official HHS data into applications by testing queries through a natural language interface.

Why teams choose Vinkius for HealthData.gov (HHS Open Data) in LangChain
The HealthData.gov (HHS Open Data) MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 2 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in LangChain only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
HealthData.gov (HHS Open Data) for LangChain
Every tool call from LangChain to the HealthData.gov (HHS Open Data) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
How do I find a specific dataset about 'Medicare'?
Use the get_catalog tool and provide 'Medicare' in the q parameter. This will return a list of relevant datasets along with their unique identifiers (dataset_id).
Can I filter results to only show data from a specific state?
Yes! When using query_dataset, use the $where parameter with a SoQL filter like state='NY'. You can also use $select to pick specific columns.
Is an API key required to access this data?
No, the data is public. However, providing a HEALTHDATA_APP_TOKEN is recommended for higher rate limits if you plan to perform many queries.
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.
