No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/search_datasets for the schema, then POST the same URL with its arguments for the data.

Search HealthData.gov for public-health datasets by keyword (e.g. “COVID hospitalizations”, “Medicare spending”, “opioid prescriptions”). Returns each dataset’s Socrata id (a 4x4 like “g62h-syeh”), title, description, owning agency, tags, when the data was last updated, and its page-view count. Pass the id to get_dataset for full metadata or to get_rows to read the actual rows.

Parameters

`limit`	number	no	Max results, 1-50 (default 10).
`offset`	number	no	Skip this many results, for paging (default 0).
