fda_device_event_counts

Pack: fda-devices · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

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

Aggregate MAUDE reports for a device query by event type, manufacturer, product code, or receive date. Counts reflect reporting and database artifacts—not event rates or causal risk—and must not be compared without exposure denominators.

Parameters

count_fieldstringyesWhat to rank by. For “which DEVICES had the most reports” use device.generic_name.exact (device type) or device.brand_name.exact (specific product).
limitnumbernoBuckets (1-100, default 20).
