MAUDE
LiveManufacturer and User Facility Device Experience
MAUDE contains reports of adverse events involving medical devices submitted to the U.S. FDA by manufacturers, importers, and user facilities. This MCP lets an AI assistant search, retrieve, and aggregate those reports directly — no manual form-filling on the FDA site. Beyond keyword search, it also lets an assistant search by meaning — finding relevant events by concept even when the wording differs.

Tools
-
search_reportsSearch MAUDE reports by free text and/or filters — device/brand, manufacturer, product code, event type, date range, and normalized concept facets. -
semantic_search_reportsSearch reports by meaning, not just exact keywords — finds relevant adverse events by concept. -
get_reportRetrieve the full detail of a single adverse event report by its MDR key. -
aggregate_reportsCount and group reports by manufacturer, brand, product code, event type, or normalized concept facets — or as a time trend. -
top_problemsSurface the most common device or patient problem descriptions across a matching set of reports. -
resolveNormalize lay terms and abbreviations to standard medical terms, for precise filtering.
Example questions
- "How many adverse events were reported for insulin pumps in 2023?"
- "Find reports about an insulin pump delivering the wrong dose."
- "Show me malfunction reports for Medtronic pacemakers, most recent first."
- "Which manufacturers have the most reported device deaths this year?"
About this dataset
The MAUDE database houses medical device reports (MDRs) of suspected device-associated deaths, serious injuries, and malfunctions. It is one of the FDA’s primary post-market surveillance tools.
What you can ask
Once connected, ask your assistant plain-English questions — it translates them
into the underlying searches and returns structured results. Hits include an
official url to the FDA MAUDE detail page so you can verify each report.
Search by meaning
Beyond keyword search, PolarisRay can search reports by meaning rather than exact words. Ask for reports “about” or “similar to” a problem and it surfaces conceptually related adverse events even when the narrative is phrased differently — and the usual filters (device, manufacturer, event type, …) still apply.
Caveats
MAUDE data has known limitations: underreporting, inconsistent data quality, and duplicate reports are common. Counts should be treated as signals, not statistics. Always confirm findings against the primary report and the FDA’s own guidance before drawing conclusions.
