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.

Google ADK natively supports openFDA as an MCP tool provider. declare Vinkius Edge URL and the framework handles discovery, validation, and execution automatically. Combine 3 tools with Gemini's long-context reasoning for complex multi-tool workflows, with production-ready session management and evaluation built in.

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 Google ADK in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

openFDA + Google ADK FAQ

Common questions about integrating openFDA MCP Server with Google ADK.

How does Google ADK connect to MCP servers?

Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.

Can ADK agents use multiple MCP servers?

Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.

Which Gemini models work best with MCP tools?

Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
