MCP Healthcare Server

An MCP (Model Context Protocol) server that gives LLMs real-time access to healthcare data — drug interactions, ICD-10 codes, FDA adverse events, Medicare statistics, and clinical guidelines.

---

What is MCP?

Model Context Protocol (MCP) is an open standard by Anthropic for connecting LLMs to external data sources and tools. Instead of hardcoding data into prompts, MCP lets LLMs dynamically call tools to fetch real-time information.

This server exposes 6 healthcare tools that any MCP-compatible client (Claude Desktop, Cursor, etc.) can use.

Available Tools

Tool	Description	Data Source
drug_interaction	Check interactions between two drugs	openFDA API
icd10_lookup	Look up ICD-10-CM diagnosis code descriptions	NLM Clinical Tables API
icd10_search	Search ICD-10-CM codes by keyword	NLM Clinical Tables API
fda_adverse_events	Get FDA adverse event reports for a drug	openFDA API
medicare_drug_statistics	Medicare Part D prescribing data	CMS.gov API
clinical_guidelines	Search PubMed for clinical guidelines	NCBI/PubMed E-utilities

All APIs are free and require no API keys.

Quick Start

Use with Claude Desktop

1. Install the server:

git clone https://github.com/shinegami-2002/mcp-healthcare-server.git
cd mcp-healthcare-server
pip install -e .

2. Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "healthcare": {
      "command": "python",
      "args": ["/absolute/path/to/mcp-healthcare-server/src/server.py"]
    }
  }
}

3. Restart Claude Desktop. You'll now see healthcare tools available in the tool picker.

Use with Docker

docker build -t mcp-healthcare .
docker run mcp-healthcare

Example Output

Drug Interaction Check

> drug_interaction("warfarin", "aspirin")

## Drug Interaction: Warfarin <-> Aspirin

**Coumadin** (warfarin):
Drugs may interact with warfarin sodium through pharmacodynamic or
pharmacokinetic mechanisms. Pharmacodynamic mechanisms for drug interactions
with warfarin sodium include synergism (impaired hemostasis, reduced
clotting factor synthesis), competitive antagonism...

ICD-10 Code Lookup

> icd10_lookup("E11")

Codes matching 'E11':
- **E11.00**: Type 2 diabetes mellitus with hyperosmolarity without NKHHC
- **E11.01**: Type 2 diabetes mellitus with hyperosmolarity with coma
- **E11.10**: Type 2 diabetes mellitus with ketoacidosis without coma
- **E11.21**: Type 2 diabetes mellitus with diabetic nephropathy
- **E11.9**: Type 2 diabetes mellitus without complications
