Local Development

Setup

1. Clone the repository and install dependencies:

npm install

1. Create a .env file:

cp .env.example .env
# Edit .env and add your CLICKUP_API_KEY

1. Run in development mode:

npm run dev

1. Test the health endpoint:

curl http://localhost:8080/health

Building

npm run build

Google Cloud Deployment

Quick Deploy

1. Set environment variables:

export GCP_PROJECT_ID="your-project-id"
export CLICKUP_API_KEY="your-clickup-api-key"
export MCP_API_KEY="optional-mcp-api-key"  # For securing the MCP endpoint

1. Run the deployment script:

./deploy.sh

The script will:

• Enable required Google Cloud APIs
• Store API keys in Secret Manager
• Build and push Docker image to Container Registry
• Deploy to Cloud Run
• Output the service URL

Manual Deployment

1. Build the Docker image:

docker build -t gcr.io/YOUR_PROJECT_ID/mcp-server-clickup .

1. Push to Container Registry:

gcloud auth configure-docker
docker push gcr.io/YOUR_PROJECT_ID/mcp-server-clickup

1. Create secrets in Secret Manager:

echo -n "your-clickup-api-key" | gcloud secrets create clickup-api-key --data-file=-
echo -n "your-mcp-api-key" | gcloud secrets create mcp-api-key --data-file=-

1. Deploy to Cloud Run:

gcloud run deploy mcp-server-clickup \
  --image gcr.io/YOUR_PROJECT_ID/mcp-server-clickup \
  --region us-central1 \
  --platform managed \
  --allow-unauthenticated \
  --set-secrets=CLICKUP_API_KEY=clickup-api-key:latest,MCP_API_KEY=mcp-api-key:latest

Client Configuration

After deployment, configure your MCP client to connect to the Cloud Run service:

{
  "mcpServers": {
    "clickup": {
      "url": "https://mcp-server-clickup-xxxxx.run.app/mcp/sse",
      "apiKey": "your-mcp-api-key"
    }
  }
}

API Authentication

The server supports two levels of authentication:

1. ClickUp API Key (Required): Authenticates with ClickUp's API
2. MCP API Key (Optional): Secures the MCP endpoint from unauthorized access

If MCP_API_KEY is set, clients must include it in the Authorization header:

Authorization: Bearer your-mcp-api-key

Architecture

• Transport: HTTP with Server-Sent Events (SSE) for Cloud Run compatibility
• Rate Limiting: Built-in rate limiter respects ClickUp's API limits (100 req/min)
• Error Handling: Comprehensive error handling with meaningful error messages
• Security: API keys stored in Google Secret Manager
• Scalability: Auto-scales on Cloud Run based on demand

CI/CD with Cloud Build

The included cloudbuild.yaml enables automatic deployment on git push:

1. Connect your GitHub repository to Cloud Build
2. Set up a trigger for your main branch
3. Commits will automatically build and deploy

Monitoring

View logs and metrics in Google Cloud Console:

• Cloud Run logs: Shows request logs and application output
• Cloud Monitoring: Track performance metrics
• Error Reporting: Aggregate and analyze errors

Cost Optimization

• Cloud Run charges only when handling requests
• Configure max instances to control costs
• Use Cloud Monitoring to track usage
• Consider setting up budget alerts

Troubleshooting

Common Issues

1. Authentication Failed: Verify your ClickUp API key is correct
2. Rate Limit Exceeded: The built-in rate limiter should prevent this
3. Deployment Fails: Check that all required APIs are enabled
4. Connection Timeout: Increase the timeout in Cloud Run configuration

Debug Mode

For local debugging:

NODE_ENV=development npm run dev

Security Best Practices

1. Always use Secret Manager for API keys
2. Enable MCP_API_KEY for production deployments
3. Configure Cloud Armor for DDoS protection (optional)
4. Set up VPC Service Controls for additional security
5. Regularly rotate API keys
