Cursor

Configure Cursor IDE to access your Netdata infrastructure through MCP.

Transport Support

Cursor’s MCP client natively supports multiple transports (https://cursor.com/docs/context/mcp):

Transport	Support	Netdata Version	Notes
stdio	✅ Fully Supported	v2.6.0+	Launch Netdata via nd-mcp or npx mcp-remote
SSE	✅ Fully Supported	v2.7.2+	Configure type: "sse" with Netdata SSE endpoint
Streamable HTTP	✅ Fully Supported	v2.7.2+	Configure type: "streamable-http" for Netdata HTTP endpoint
WebSocket	❌ Not Supported	-	Use the stdio bridge for v2.6.0–v2.7.1

Prerequisites

1. Cursor installed - Download from cursor.com
2. Netdata v2.6.0 or later with MCP support - Prefer a Netdata Parent to get infrastructure level visibility. Your AI Client (running on your desktop or laptop) needs to have direct network access to the Netdata IP and port (usually 19999).
   • v2.6.0 - v2.7.1: Only WebSocket transport is available, so launch Netdata through nd-mcp
   • v2.7.2+: Expose Netdata over SSE or HTTP directly, or continue to use nd-mcp
3. Optional bridge - npx mcp-remote@latest remains useful if you prefer stdio-only setups or want to re-use the same launcher for multiple clients.
4. Netdata MCP API key loaded into the environment (recommended) - export it before launching Cursor:

   export ND_MCP_BEARER_TOKEN="$(cat /var/lib/netdata/mcp_dev_preview_api_key)"

   Each Netdata Agent or Parent has its own unique API key for MCP - Find your Netdata MCP API key

Configuration Methods

Cursor reads MCP definitions from .cursor/mcp.json in the workspace root. For user-wide defaults, open Cursor’s Settings and add the same structure to the global config path documented by Cursor (https://cursor.com/docs/context/mcp#configuration-locations).

Method 1: stdio Bridge (All Netdata versions)

{
  "mcpServers": {
    "netdata": {
      "type": "stdio",
      "command": "/usr/sbin/nd-mcp",
      "args": [
        "ws://YOUR_NETDATA_IP:19999/mcp"
      ]
    }
  }
}

Method 2: Direct SSE (Netdata v2.7.2+)

{
  "mcpServers": {
    "netdata": {
      "type": "sse",
      "url": "https://YOUR_NETDATA_IP:19999/mcp",
      "headers": {
        "Authorization": "Bearer NETDATA_MCP_API_KEY"
      }
    }
  }
}

Method 3: Streamable HTTP (Netdata v2.7.2+)

{
  "mcpServers": {
    "netdata": {
      "type": "streamable-http",
      "url": "https://YOUR_NETDATA_IP:19999/mcp",
      "headers": {
        "Authorization": "Bearer NETDATA_MCP_API_KEY"
      }
    }
  }
}

Cursor supports config interpolation such as $\{env:NETDATA_MCP_API_KEY} or $\{workspaceFolder} inside command, args, env, url, and headers (https://cursor.com/docs/context/mcp#config-interpolation). Use these to avoid storing secrets in plain text.

After editing .cursor/mcp.json, restart Cursor or run “Reload Window” for the new server to appear in Settings → MCP.

Using Netdata in Cursor

In Chat (Cmd+K)

Reference Netdata directly in your queries:

@netdata what's the current CPU usage?
@netdata show me database query performance
@netdata are there any anomalies in the web servers?

In Code Comments

Get infrastructure context while coding:

# @netdata what's the typical memory usage of this service?
def process_large_dataset():
    # Implementation

Multi-Model Support

Cursor's strength is using multiple AI models. You can:

• Use Claude for complex analysis
• Switch to GPT-4 for different perspectives
• Use smaller models for quick queries

All models can access your Netdata data through MCP.

Multiple Environments

Cursor allows multiple MCP servers but requires manual toggling:

{
  "mcpServers": {
    "netdata-prod": {
      "type": "stdio",
      "command": "/usr/sbin/nd-mcp",
      "args": ["ws://prod-parent:19999/mcp"]
    },
    "netdata-dev": {
      "type": "stdio",
      "command": "/usr/sbin/nd-mcp",
      "args": ["ws://dev-parent:19999/mcp"]
    }
  }
}

Use the toggle in settings to enable only the environment you need.

ℹ️ Before switching environments, set ND_MCP_BEARER_TOKEN to the matching key so the bridge picks up the correct credentials without embedding them in the config file.

Best Practices

Infrastructure-Aware Development

While coding, ask about:

• Current resource usage of services you're modifying
• Historical performance patterns
• Impact of deployments on system metrics

Debugging with Context

@netdata show me the logs when this error last occurred
@netdata what was the system state during the last deployment?
@netdata find correlated metrics during the performance regression

Performance Optimization

@netdata analyze database query latency patterns
@netdata which endpoints have the highest response times?
@netdata show me resource usage trends for this service

Troubleshooting

MCP Server Not Available

• Restart Cursor after adding configuration
• Verify JSON syntax in settings
• Check MCP is enabled in Cursor settings

Connection Issues

• Test Netdata accessibility: curl http://YOUR_NETDATA_IP:19999/api/v3/info
• Verify bridge path is correct and executable
• Check firewall allows connection to Netdata

Multiple Servers Confusion

• Cursor may query the wrong server if multiple are enabled
• Always disable unused servers
• Name servers clearly (prod, dev, staging)

Limited Functionality

• Ensure API key is included for full access
• Verify Netdata agent is claimed
• Check that required collectors are enabled
