Medical

This Medical MCP Server lets you bring trusted, authorative medical data directly into your AI workflows in a private, local environment. It provides access to sources like FDA, WHO, PubMed, RxNorm, and Google Scholar without API keys or data leaving your machine, and it supports quick setup for developers and researchers who want fast, private access to medical information.

How to use

You run the server locally and connect your MCP client to the local process. The server exposes a set of tools for drug information, health statistics, medical literature, clinical guidelines, and pediatric sources. Use these tools to query drug details, search literature, retrieve health indicators, and access pediatric guidelines without leaving your device.

How to install

Prerequisites: Node.js 18+ and npm. Ensure you have a compatible shell or terminal to run commands.

# Clone the project, install dependencies, and build
git clone https://github.com/JamesANZ/medical-mcp.git
cd medical-mcp
npm install
npm run build

# Run the server
npm start

Additional setup and configuration

Claude Desktop can connect to the local server by adding a configuration entry that launches the server through Node.js and points to the built index. Place this configuration file in the appropriate Claude Desktop path and restart Claude Desktop afterward.

Security, privacy, and performance notes

• Localhost-only operation ensures the server runs entirely on your machine with no external access.
• No data storage: queries are processed in real time and not persisted.
• Process isolation keeps medical data contained within the server process.
• No API keys are required, minimizing credential management.

Caching and performance

The server includes an in-memory caching layer to speed responses and reduce external API usage. Cache TTLs are source-specific (e.g., FDA data 24 hours, PubMed 1 hour, WHO 7 days, etc.). Automatic cleanup runs every 5 minutes, with Least Recently Used eviction when the cache grows beyond capacity.

Data sources and coverage

Key sources include FDA, WHO, PubMed, RxNorm, Google Scholar, AAP, and pediatric journals. Data categories span drug information, health statistics, medical literature, clinical guidelines, and pediatric care data.
