Do I need an API Key?

No. This zero-auth integration allows up to 1,000 requests per day (per IP address) right out of the box, covering most standard agent usage scenarios.

How do search queries work?

The API gives you massive flexibility. The AI agent can format search strings using standard query syntax (e.g. `reason_for_recall:salmonella AND state:CA`).

About openFDA MCP Server

The openFDA MCP Server provides direct, zero-auth access to the United States Food and Drug Administration (FDA) regulatory databases. This server allows your AI agent to construct complex pharmacological queries and retrieve public health data in real-time.

LlamaIndex agents combine openFDA tool responses with indexed documents for comprehensive, grounded answers. Connect 3 tools through the Vinkius and query live data alongside vector stores and SQL databases in a single turn — ideal for hybrid search, data enrichment, and analytical workflows.

Core Capabilities

Drug Adverse Events — Investigate documented side effects, medication errors, and quality complaints across millions of historical patient records.
Food Safety Recalls — Keep track of active and historical FDA enforcement reports, including outbreaks of pathogens like Salmonella or Listeria.
Medical Device Safety (MAUDE) — Monitor injuries, malfunctions, and deaths associated with medical devices.
Advanced Search Capabilities — All tools accept raw query syntax, giving your AI agent absolute freedom to perform highly granular, multi-variable analytical research.

Ideal for healthcare researchers, compliance officers, and public safety analysts requiring deep programmatic data scraping without the overhead of API key management.

The openFDA MCP Server exposes 3 tools through the Vinkius. Connect it to LlamaIndex in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
