OpenFDA MCP Server

An MCP (Model Context Protocol) server that provides access to U.S. FDA public datasets including drugs, medical devices, adverse events, recalls, and more.

Features

10 FDA Tools: Query drug and device databases through a standardized MCP interface
Drug Tools: Adverse events (FAERS), labels, NDC directory, recalls, Drugs@FDA, shortages
Device Tools: 510(k) clearances, classifications, adverse events (MDR), recalls
Individual Record Lookup: Retrieve specific reports by ID (safety report ID, set ID, MDR report number)
Advanced Filtering: Filter drug labels by boxed warnings, request specific label sections
Rate Limit Aware: Supports authenticated requests for higher rate limits (120k/hour vs 1k/hour)
TypeScript: Fully typed with Zod schema validation

Installation

# Install globally
npm install -g openfda-mcp-server

# Or use with npx
