Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

cdc
cdc_discover_datasets
Search the CDC dataset catalog by keyword, category, or tag. Returns dataset IDs, names, truncated descriptions, column counts, and update timestamps. Use cdc_get_dataset_schema for the full column list of a chosen dataset.
cdc_get_dataset_schema
Fetch the full column schema for a CDC dataset — names, data types, descriptions, row count, and last-updated timestamp. Get dataset IDs from cdc_discover_datasets.
cdc_query_dataset
Execute a SoQL query against any CDC dataset. Supports filtering, aggregation, sorting, full-text search, and field selection. Use cdc_discover_datasets to find dataset IDs and cdc_get_dataset_schema to inspect columns before querying.
cdc_query_wonder
Query CDC WONDER for national US mortality statistics — deaths, population, and crude/age-adjusted death rates — from the Underlying Cause of Death database (D76, 1999–2020). Break results out by year, age group, sex, and/or race, and filter by ICD-10 cause of death, sex, age group, or year range. WONDER is a separate CDC system from the Socrata datasets the other cdc_* tools query. Data is national only — sub-national (state/county) breakdowns are not available through the API (CDC vital-statistics policy). Cause of death is a filter, not a grouping. CDC suppresses any cell with fewer than 10 deaths (returned as null). The API is rate-limited to one request every ~15 seconds, so requests may be briefly spaced.

Cdc Health MCP Server — questions

Answers built from our own checks of this server.

What can Cdc Health MCP Server do?
It exposes 4 tools, read directly from the server on our last check. Among them: cdc_discover_datasets, cdc_get_dataset_schema, cdc_query_dataset, cdc_query_wonder. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Cdc Health MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 393 ms. The bar chart above shows every period we have measured.
How do I connect Cdc Health MCP Server?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Cdc Health MCP Server need an API key?
No. Cdc Health MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Cdc Health MCP Server?
It answers our handshake in 393 ms on average, which is faster than 35% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Cdc Health MCP Server?
The npm package @cyanheads/cdc-health-mcp-server was installed 122 times in the last week. Week over week that is -2%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Cdc Health MCP Server open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 3 stars on GitHub and 4 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
