MCP Healthcare Server

A Model Context Protocol (MCP) server that bundles healthcare data tools for use with Claude Desktop, Cursor, and other MCP clients.

Tools (10 total)

ICD-10-CM Diagnosis Codes (74,260 codes from CMS 2025)

Tool	Description
icd10_lookup	Look up an ICD-10-CM code by code string (e.g., E11.9)
icd10_search	Search codes by keyword (e.g., "diabetes", "chest pain")
icd10_validate	Check if a code exists in the 2025 code set

NPI Provider Registry (live NPPES queries)

Tool	Description
npi_search	Search providers by name, specialty, city, state, ZIP
npi_lookup	Look up a provider by 10-digit NPI number

NDC Drug Directory (111,655 FDA products)

Tool	Description
ndc_lookup	Look up a drug by NDC code (e.g., 0002-1433-80)
ndc_search	Search drugs by name, generic name, or manufacturer
ndc_search_ingredient	Search drugs by active ingredient

DEA Number Validation (algorithm-based)

Tool	Description
dea_validate	Validate a DEA number using the official checksum algorithm
dea_generate_test	Generate a valid test DEA number for development

Setup

Prerequisites

• Node.js 18+
• The ICD-10 and NDC data files from sibling API directories

Install

cd mcp-healthcare
npm install
npm run link-data   # creates symlinks to ICD-10 and NDC data files

Claude Desktop Configuration

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "healthcare": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-healthcare/src/index.js"]
    }
  }
}

Cursor Configuration

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "healthcare": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-healthcare/src/index.js"]
    }
  }
}

Data Sources

Dataset	Source	Update Frequency
ICD-10-CM	CMS (Centers for Medicare & Medicaid)	Annually (October)
NDC	FDA National Drug Code Directory	Weekly
NPI	NPPES Registry (live API)	Real-time
DEA	Checksum algorithm (no dataset)	N/A

Transport

This server uses stdio transport (stdin/stdout), which is the standard for local MCP integrations with Claude Desktop and Cursor. No HTTP server is started.

Architecture

The server imports pure business logic extracted from four Express-based REST APIs:

• src/tools/icd10.js — ICD-10 code lookup, search, validation (loads 6MB JSON dataset)
• src/tools/ndc.js — NDC drug lookup and search (loads 53MB JSON dataset)
• src/tools/npi.js — NPI provider search via live NPPES API
• src/tools/dea.js — DEA number validation (pure algorithm, no dataset)

Data files are symlinked from sibling API directories to avoid duplication.
