mcp-ratchet-clinical-charting

MCP server for clinical charting with Claude (codename: Ratchet) - Enables Claude to document patient visits directly into Electronic Medical Records, reducing administrative burden for home health nurses.

Note: Currently runs in Mock Mode for development/testing. Production EMR integration coming soon.

Status

Current Mode: Mock Mode - Uses realistic test data for development and testing.

Quick Start

From npm (Recommended)

npx mcp-ratchet-clinical-charting

From Source

git clone https://github.com/m2ai-mcp-servers/mcp-ratchet-clinical-charting.git
cd mcp-ratchet-clinical-charting
npm install
npm run build
npm run dev  # Development mode
npm test     # Run tests

Mock Mode

Ratchet runs in mock mode by default when POINTCARE_API_URL is not configured. Mock mode:

• Uses 5 fictional test patients
• Stores visit notes in memory
• Returns realistic responses
• Perfect for development and Claude Desktop testing

Available Tools

Example Usage (in Claude)

"Search for patient Eleanor Thompson"
→ Returns patient PT-10001 with demographics and status

"Create a visit note for PT-10001 with blood pressure 120/80"
→ Creates and stores visit note with vitals

"Get visit history for PT-10001"
→ Returns list of previous visits

Claude Desktop Integration

Configure Claude Desktop

Add to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "ratchet": {
      "command": "npx",
      "args": ["-y", "mcp-ratchet-clinical-charting"]
    }
  }
}

For production mode with EMR integration:

{
  "mcpServers": {
    "ratchet": {
      "command": "npx",
      "args": ["-y", "mcp-ratchet-clinical-charting"],
      "env": {
        "POINTCARE_API_URL": "https://api.pointcare.com",
        "POINTCARE_API_KEY": "your-api-key"
      }
    }
  }
}

Origin Story

Ratchet evolved from the M2AI NurseCall n8n workflow, built to help home health nurses with visit documentation:

Current Flow (M2AI NurseCall):
┌─────────┐    ┌─────────┐    ┌─────────┐    ┌─────────┐
│ Twilio  │───>│  n8n    │───>│  VAPI   │───>│  Email  │
│  SMS    │    │ Workflow│    │  Call   │    │ Summary │
└─────────┘    └─────────┘    └─────────┘    └─────────┘

The Problem: Visit notes go to email but still need manual entry into PointCare EMR.

Ratchet's Solution:

Future Flow (with Ratchet):
┌─────────┐    ┌─────────┐    ┌──────────┐    ┌───────────┐
│ Twilio  │───>│  n8n    │───>│ Ratchet  │───>│ PointCare │
│  SMS    │    │ Workflow│    │   MCP    │    │    EMR    │
└─────────┘    └──────
