What is the CDC WONDER (Epidemiologic Data) MCP Server?
Connect to the CDC WONDER (Wide-ranging Online Data for Epidemiologic Research) system to query massive public health databases through natural language.
What you can do
- Mortality Data — Query the D76 (Detailed Mortality) and D77 (Underlying Cause of Death) databases for specific timeframes and regions.
- Birth Statistics — Access the D10 (Natality) database to analyze birth rates and maternal health metrics.
- Vaccine Safety — Query the VAERS (Vaccine Adverse Event Reporting System) database for safety monitoring data.
- Structured Queries — Execute complex ad-hoc queries using standard CDC parameters (B_, M_, V_, F_, O_ prefixes) for precise data extraction.
- Epidemiologic Research — Retrieve raw data for analysis in scientific research, public health policy, or educational projects.
How it works
- Subscribe to this server
- Enter your CDC WONDER API Access Token (if required by your proxy) or accept the Data Use Agreement
- Start querying epidemiologic data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Epidemiologists & Researchers — quickly pull mortality and birth statistics without navigating the complex WONDER web interface
- Public Health Officials — monitor health trends and vaccine safety reports directly from an AI assistant
- Data Scientists — fetch structured JSON epidemiologic data for integration into larger analytical workflows
Built-in capabilities (1)
g., D76 for Mortality). Provide the database ID and a JSON object of parameters (B_, M_, V_, F_, O_ prefixes). Query CDC WONDER epidemiologic databases

Why teams choose Vinkius for CDC WONDER (Epidemiologic Data) in LlamaIndex
The CDC WONDER (Epidemiologic 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 1 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in LlamaIndex 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
CDC WONDER (Epidemiologic Data) for LlamaIndex
Every tool call from LlamaIndex to the CDC WONDER (Epidemiologic Data) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Which databases can I access using this server?
You can query any database supported by the CDC WONDER API by providing its ID to the query_wonder_database tool. Common IDs include D76 (Detailed Mortality), D10 (Natality), and VAERS (Vaccine Adverse Event Reporting System).
How should I format the parameters for a query?
Parameters should be provided as a JSON object using the standard CDC prefixes: B_ for by-variables, M_ for measures, V_ for values, F_ for filters, and O_ for other options. The query_wonder_database tool handles the XML conversion for you.
Do I need to include the 'accept_datause_restrictions' parameter?
No. The query_wonder_database tool is designed to handle the data use restrictions agreement internally. You only need to provide the specific database ID and the analytical parameters for your search.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query CDC WONDER (Epidemiologic Data) tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
