## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-cdc).
  - Clear OSI-approved license (MIT).

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 84, +1)

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

First indexed and scored.

## MCP tools (4)

### `search_datasets` (~69 tokens)

Search CDC public health datasets by keyword. Returns dataset names, descriptions, IDs, and update dates. Example: search_datasets("influenza surveillance").

Input parameters:

- `query` (string, required): Search keywords (e.g., "covid cases", "influenza", "vaccination rates", "mortality")

### `get_dataset` (~116 tokens)

Fetch up to 1000 rows from a CDC Socrata dataset by its four-by-four dataset ID (e.g., "9mfq-cb36"). Returns row array with all columns plus column names extracted from the first row. Use search_datasets first to find the dataset ID.

Input parameters:

- `id` (string, required): Socrata dataset ID in four-by-four format (e.g., "9mfq-cb36")
- `limit` (number): Number of rows to return (default 50, max 1000)

### `wastewater_national_trend` (~195 tokens)

National CDC NWSS wastewater viral activity level (WVAL) for SARS-CoV-2, influenza A, or RSV — the leading public signal for near-term respiratory infection and test-demand trends, published weekly (Fridays) from ~800+ US sewershed sites. Returns the latest week's national level (Very Low/Low/Moderate/High/Very High, population-weighted across reporting sites), the category breakdown, and a week-over-week trend. Example: wastewater_national_trend({"pathogen":"SARS-CoV-2"}).

Input parameters:

- `pathogen` (string): Pathogen: "SARS-CoV-2" (aliases: covid, covid-19), "Influenza A" (aliases: flu, influenza), or "RSV". Default SARS-CoV-2.
- `weeks` (number): Trailing weeks of history to include (default 4, max 12).

### `wastewater_state_trend` (~171 tokens)

CDC NWSS wastewater viral activity level (WVAL) for one US state or territory — same population-weighted national methodology as wastewater_national_trend, scoped to reporting sites within the state. Example: wastewater_state_trend({"state":"California","pathogen":"SARS-CoV-2"}).

Input parameters:

- `pathogen` (string): Pathogen: "SARS-CoV-2" (aliases: covid, covid-19), "Influenza A" (aliases: flu, influenza), or "RSV". Default SARS-CoV-2.
- `state` (string, required): US state, DC, or territory name or postal abbreviation (e.g. "California" or "CA").
- `weeks` (number): Trailing weeks of history to include (default 4, max 12).

## Common questions

### What is the Cdc MCP server?

Cdc is an MCP server listed in the public MCP registry as io.github.pipeworx-io/cdc. CDC MCP, wraps CDC open data via Socrata API (data.cdc.gov). This page covers its npm package (@pipeworx/mcp-cdc).

### Is the Cdc MCP server safe to use?

Cdc scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Cdc MCP server expose?

Cdc exposes 4 tools: search_datasets, get_dataset, wastewater_national_trend, wastewater_state_trend. Their descriptions and schemas cost roughly 551 tokens of context every time the server is loaded.

### Is the Cdc MCP server still maintained?

Cdc is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Cdc MCP server under?

Cdc declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Cdc MCP server?

VerifyMCP ran 16 checks on Cdc, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
