Tools Exposed

Prerequisites

• Node.js >= 18.0.0
• n8n instance (cloud or self-hosted) with API access
• n8n API Key (generate in n8n Settings > API)

Install directly from mcp.so using Smithery:

npx @smithery/cli install careflow-mcp

This will automatically:

• Install the package
• Add to your Claude Desktop config
• Prompt for required environment variables

Option 2: NPM Installation

npm install -g careflow-mcp

# Clone the repository
git clone https://github.com/pratapsfdc22-dev/careflow-mcp.git
cd careflow-mcp

# Install dependencies
npm install

# Build the project
npm run build

# Link globally (optional)
npm link

Configuration

1. Create Environment File

cp .env.example .env

2. Configure Environment Variables

Edit .env with your n8n credentials:

3. Configure Claude Desktop

Add to your claude_desktop_config.json:

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

{
  "mcpServers": {
    "n8n-workflow": {
      "command": "node",
      "args": [
        "/path/to/careflow-mcp/dist/index.js"
      ],
      "env": {
        "N8N_BASE_URL": "https://your-n8n-instance.com",
        "N8N_API_KEY": "your_api_key_here",
        "N8N_WEBHOOK_SECRET": "your_webhook_secret"
      }
    }
  }
}

Using npm global install:

{
  "mcpServers": {
    "n8n-workflow": {
      "command": "careflow-mcp",
      "env": {
        "N8N_BASE_URL": "https://your-n8n-instance.com",
        "N8N_API_KEY": "your_api_key_here"
      }
    }
  }
}

Usage Examples

1. Trigger a Workflow

// Ask Claude:
"Trigger the 'Customer Onboarding' workflow with this data:
{ email: 'user@example.com', name: 'John Doe' }"

2. List All Active Workflows

// Ask Claude:
"Show me all active n8n workflows"

3. Check Workflow Execution Status

// Ask Claude:
"Check the status of execution ID: abc123"

4. Create a Patient Task

// Ask Claude:
"Create a high-priority follow-up task for patient ID P12345
in the 'Patient Care' workflow, due tomorrow"

API Reference

trigger_workflow

Triggers an n8n workflow by name with optional JSON payload.

Input:

{
  workflowName: string;    // Name of the workflow
  payload?: object;        // Optional JSON data
}

Output:

{
  "success": true,
  "workflowId": "abc123",
  "workflowName": "Customer Onboarding",
  "response": { ... }
}

list_workflows

Lists all active workflows from n8n instance.

Input: None

{
  "success": true,
  "count": 5,
  "workflows": [
    {
      "id": "abc123",
      "name": "Customer Onboarding",
      "active": true,
      "createdAt": "2024-01-01T00:00:00.000Z",

    }
  ]
}

get_workflow_status

{
  executionId: string;    // Execution ID from trigger response
}

{
  "success": true,
  "execution": {
    "id": "exec123",

  workflowName: string;          // Target workflow
  patientId: string;             // Patient identifier
  taskType: string;              // Task type
  priority?: "low" | "medium" | "high" | "urgent";

Error Handling

The server implements comprehensive error handling with proper MCP error codes:

• Invalid Parameters - ErrorCode.InvalidParams
• Method Not Found - ErrorCode.MethodNotFound
• Internal Error - ErrorCode.InternalError

All errors include descriptive messages for debugging.

Security Best Practices

1. Never commit .env - Always use .env.example for templates
2. Rotate API keys - Regularly update your n8n API keys
3. Use webhook secrets - Add authentication to webhook triggers
4. Restrict API access - Use n8n's API key permissions
5. Monitor logs - Check server logs for suspicious activity

Troubleshooting

Server won't start

# Check Node.js version
node --version  # Should be >= 18.0.0

# Verify environment variables
cat .env

# Check TypeScript compilation
npm run build

Workflow not found

• Verify the workflow name matches exactly (case-sensitive)
• Ensure the workflow is active in n8n
• Check API key has permission to access workflows

Authentication failed

• Verify N8N_API_KEY is correct
• Check N8N_BASE_URL includes protocol (https://)
• Ensure API key hasn't expired

Webhook trigger fails

• Verify webhook node exists in workflow
• Check webhook path matches workflow ID
• Confirm N8N_WEBHOOK_SECRET if required
