Overview

AI-generated overview

Lets an assistant search openFDA public datasets on drugs, devices, food, and adverse events through a hosted remote endpoint.

What it does
Provides read-only search tools over openFDA datasets, including drug adverse-event reports (FAERS), drug labels (SPL), the National Drug Code directory, drug recalls, Drugs@FDA approvals, and drug shortages. Device tools cover adverse events (MAUDE), 510(k) clearances, recalls, and classification; food tools cover adverse events (CAERS) and recalls. A count tool aggregates over a dataset, and a generic query tool reaches any openFDA endpoint.
When to use it
Useful when an assistant needs regulatory, safety, or recall information about drugs, medical devices, food, supplements, or cosmetics from official US openFDA data. Suited to research, pharmacovigilance-style lookups, and answering questions about approvals, labels, shortages, or enforcement reports.
Requirements
A remote streamable HTTP endpoint; no local install and no credential, since openFDA is a public data source. On first connect the user approves the link, and usage is metered to a private id. Network access to the hosted endpoint is required.
Before you install
All listed tools are read-only, so nothing is written, sent, or deleted. Usage is metered to a private id and the free plan is limited to 100 tool calls per month, with paid plans for unlimited use, so costs can apply. Queries are sent to the hosted third-party endpoint rather than directly to openFDA.
