🔒 Security

Creating a Service Account Token (Recommended)

1. In Grafana UI:

   • Go to Administration → Service accounts
   • Click "Add service account"
   • Name it (e.g., "mcp-server")
   • Click "Create"
   • Click "Add service account token"
   • Generate token and copy it

2. Required Permissions:

   • dashboards:read - View dashboards
   • datasources:read - View datasources
   • alert.rules:read - View alert rules
   • logs:read - Query Loki
   • metrics:read - Query Prometheus
   • incidents:write - Manage incidents (if needed)

Best Practices

• Use service account tokens instead of API keys
• Store tokens in environment variables, not in code
• Use read-only permissions where possible
• Enable TLS/mTLS for production environments
• Regularly rotate tokens

🧪 Testing

Quick Test

# Test connection
curl -H "Authorization: Bearer YOUR_TOKEN" \
  https://your-grafana.com/api/org

# Test with the MCP server
npx @leval/mcp-grafana --debug

Run Test Suite

# Clone the repository
git clone https://github.com/levalhq/mcp-grafana.git
cd mcp-grafana

# Install dependencies
npm install

# Run tests
npm test

# Test with your Grafana instance
node test/test-connection.js
node test/test-api.js

📊 Performance

• Startup time: < 1 second
• Tool registration: < 100ms for all 43 tools
• Query response: 200-500ms typical
• Memory usage: ~50MB baseline
• Connection pooling: Reuses HTTP connections

🐛 Troubleshooting

MCP Server Not Starting

# Check if running correctly
npx @leval/mcp-grafana --debug

# Should output:
# Starting MCP Grafana server with stdio transport...
# MCP server started with stdio transport

Connection Issues

# Test your credentials
curl -H "Authorization: Bearer YOUR_TOKEN" \
  https://your-grafana.com/api/org

# Check response - should return org details

Client Not Detecting Server

1. Verify configuration file location
2. Check JSON syntax is valid
3. Restart the client application
4. Look for MCP indicator in UI
5. Check client logs for errors
