Netdata MCP

Netdata provides Model Context Protocol (MCP) servers that enable AI assistants to interact with your infrastructure monitoring data. You can connect via:

Netdata Cloud — A single cloud-hosted endpoint at https://app.netdata.cloud/api/v1/mcp with full visibility across all your nodes. No bridges, no firewall changes.
Local Agent or Parent — Connect directly to any Netdata Agent or Parent (v2.6.0+) on your network at http://YOUR_IP:19999/mcp.

Both options provide comprehensive access to all available observability data through MCP:

Node Discovery - Hardware specifications, operating system details, version information, streaming topology, and associated metadata
Metrics Discovery - Full-text search capabilities across contexts, instances, dimensions, and labels
Function Discovery - Access to system functions including processes, network-connections, streaming, systemd-journal, windows-events, etc.
Alert Discovery - Real-time visibility into active and raised alerts
Metrics Queries - Complex aggregations and groupings with ML-powered anomaly detection
Metrics Scoring - Root cause analysis leveraging anomaly detection and metric correlations
Alert History - Complete alert transition logs and state changes
Function Execution - Execute Netdata functions on any connected node (requires Netdata Parent)
Log Exploration - Access logs from any connected node (requires Netdata Parent)

AI assistants have different visibility depending on where they connect:

Connection	Visibility
Netdata Cloud	All nodes across your entire infrastructure
Netdata Parent	All child nodes connected to that parent
Netdata Child/Standalone	Only that specific node

Feature	Cloud MCP	Agent/Parent MCP
Scope	All nodes	Single agent/parent
Endpoint	`app.netdata.cloud/api/v1/mcp`	`YOUR_IP:19999/mcp`
Transport	Streamable HTTP	HTTP, SSE, WebSocket
Authentication	Cloud API token (`scope:mcp`)	Local MCP API key
Network access	Internet only	Direct access to Netdata IP required
Local setup	None	Bridge may be needed for some clients

Netdata Cloud MCP

Connect AI assistants to your entire Netdata Cloud infrastructure through a single MCP endpoint — no local setup, no bridges, no firewall changes.

Prerequisites

Netdata Cloud account with a Business plan
API token with scope:mcp — Create one in API Tokens settings
Nodes claimed to Netdata Cloud — The Cloud MCP server can only access nodes connected to your Netdata Cloud space

Endpoint

https://app.netdata.cloud/api/v1/mcp

Transport: Streamable HTTP (stateless, works behind load balancers and CDNs)

Authentication

All requests to the Cloud MCP endpoint require a Bearer token in the Authorization header:

Authorization: Bearer YOUR_NETDATA_CLOUD_API_TOKEN

Creating an API Token

Log in to Netdata Cloud
Click your profile picture in the bottom-left corner
Select User Settings
Navigate to the API Tokens section
Create a new token with scope:mcp
Copy and store the token securely — you won't be able to see it again

For more details, see API Tokens.

Connection Configuration

Generic MCP Client (HTTP Transport)

For any MCP client that supports Streamable HTTP transport:

{
  "mcpServers": {
    "netdata-cloud": {
      "type": "http",
      "url": "https://app.netdata.cloud/api/v1/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_NETDATA_CLOUD_API_TOKEN"
      }
    }
  }
}

Clients Requiring stdio Bridge

For MCP clients that only support stdio transport, use npx mcp-remote as a bridge:

{
  "mcpServers": {
    "netdata-cloud": {
      "command": "npx",
      "args": [
        "mcp-remote@latest",
        "https://app.netdata.cloud/api/v1/mcp",
        "--header",
        "Authorization: Bearer YOUR_NETDATA_CLOUD_API_TOKEN"
      ]
    }
  }
}

Replace YOUR_NETDATA_CLOUD_API_TOKEN with your API token (must have scope:mcp).

Cloud MCP Troubleshooting

Authentication Errors

Verify your API token has scope:mcp
Ensure the token is passed as Authorization: Bearer <token> (not as a query parameter)
Check that your Netdata Cloud subscription includes a space in the Business plan

No Nodes Visible

Confirm your nodes are claimed to Netdata Cloud and appear in the web dashboard
Check that agents are online and streaming to Cloud

Connection Issues

The endpoint uses HTTPS — no --allow-http flag is needed
Test connectivity: curl -H "Authorization: Bearer YOUR_TOKEN" https://app.netdata.cloud/api/v1/mcp

Local Agent or Parent MCP

Connect directly to any Netdata Agent or Parent on your network. All Netdata Agents and Parents (v2.6.0+) include a built-in MCP server at http://YOUR_IP:19999/mcp.

Some MCP features — such as live process information, network connections, and full log access — are considered sensitive. These are protected by a local API key that Netdata generates automatically on startup. Without this key, AI assistants can still access metrics, alerts, and node information, but sensitive functions remain locked.

Transport Options

Netdata implements the MCP protocol with multiple transport options:

Transport	Endpoint	Use Case	Version Requirement
WebSocket	`ws://YOUR_IP:19999/mcp`	Original transport, requires nd-mcp bridge for stdio clients	v2.6.0+
HTTP Streamable	`http://YOUR_IP:19999/mcp`	Direct connection from AI clients supporting HTTP	v2.7.2+
SSE	`http://YOUR_IP:19999/sse`	Server-Sent Events for real-time streaming	v2.7.2+

Direct Connection (v2.7.2+): AI clients that support HTTP or SSE transports can connect directly to Netdata
Bridge Required: AI clients that only support stdio need the nd-mcp (stdio-to-websocket) or mcp-remote (stdio-to-http or stdio-to-sse) bridge

Official MCP Remote Client (mcp-remote)

If your AI client doesn't support HTTP/SSE directly and you don't want to use nd-mcp, you can use the official MCP remote client (requires Netdata v2.7.2+):

# Export your MCP key once per shell
export NETDATA_MCP_API_KEY="$(cat /var/lib/netdata/mcp_dev_preview_api_key)"

# For HTTP transport
npx mcp-remote@latest --http http://YOUR_NETDATA_IP:19999/mcp \
  --allow-http \
  --header "Authorization: Bearer $NETDATA_MCP_API_KEY"

# For SSE transport
npx mcp-remote@latest --sse http://YOUR_NETDATA_IP:19999/mcp \
  --allow-http \
  --header "Authorization: Bearer $NETDATA_MCP_API_KEY"

Note: The --allow-http flag is required for non-HTTPS connections. Only use this on trusted networks as traffic will not be encrypted.

Finding the nd-mcp Bridge

Note: With the new HTTP and SSE transports, many AI clients can now connect directly to Netdata without nd-mcp. Check your AI client's documentation to see if it supports direct HTTP or SSE connections.

The nd-mcp bridge is only needed for AI clients that:

Only support stdio communication (like some desktop applications)
Cannot use HTTP or SSE transports directly
Cannot use npx mcp-remote@latest

The nd-mcp bridge needs to be available on your desktop or laptop where your AI client runs. Since most users run Netdata on remote servers rather than their local machines, you have two options:

If you have Netdata installed locally - Use the existing nd-mcp
If Netdata is only on remote servers - Build nd-mcp on your desktop/laptop

Option 1: Using Existing nd-mcp

If you have Netdata installed on your desktop/laptop, find the existing bridge:

Linux

# Try these locations in order:
which nd-mcp
ls -la /usr/sbin/nd-mcp
ls -la /usr/bin/nd-mcp
ls -la /opt/netdata/usr/bin/nd-mcp
ls -la /usr/local/bin/nd-mcp
ls -la /usr/local/netdata/usr/bin/nd-mcp

# Or search for it:
find / -name "nd-mcp" 2>/dev/null

Common locations:

Native packages (apt, yum, etc.): /usr/sbin/nd-mcp or /usr/bin/nd-mcp
Static installations: /opt/netdata/usr/bin/nd-mcp
Built from source: /usr/local/netdata/usr/bin/nd-mcp

macOS

# Try these locations:
which nd-mcp
ls -la /usr/local/bin/nd-mcp
ls -la /usr/local/netdata/usr/bin/nd-mcp
ls -la /opt/homebrew/bin/nd-mcp

# Or search for it:
find / -name "nd-mcp" 2>/dev/null

Windows

# Check common locations:
dir "C:\Program Files\Netdata\usr\bin\nd-mcp.exe"
dir "C:\Netdata\usr\bin\nd-mcp.exe"
# Or search for it:
where nd-mcp.exe

Option 2: Building nd-mcp for Your Desktop

If you don't have Netdata installed locally you can build just the nd-mcp bridge. Netdata provides three implementations - choose the one that best fits your environment:

Go bridge (recommended) - Go bridge source code
- Produces a single binary with no dependencies
- Creates executable named nd-mcp (nd-mcp.exe on windows)
- Includes both build.sh and build.bat (for Windows)
Node.js bridge - Node.js bridge source code
- Good if you already have Node.js installed
- Creates script named nd-mcp.js
- Includes build.sh
Python bridge - Python bridge source code
- Good if you already have Python installed
- Creates script named nd-mcp.py
- Includes build.sh

To build:

# Clone the Netdata repository
git clone https://github.com/netdata/netdata.git
cd netdata

# Choose your preferred implementation
cd src/web/mcp/bridges/stdio-golang/  # or stdio-nodejs/ or stdio-python/

# Build the bridge
./build.sh  # On Windows with the Go version, use build.bat

# The executable will be created with different names:
# - Go: nd-mcp
# - Node.js: nd-mcp.js
# - Python: nd-mcp.py

# Test the bridge with your Netdata instance (replace localhost with your Netdata IP)
./nd-mcp ws://localhost:19999/mcp      # Go bridge
./nd-mcp.js ws://localhost:19999/mcp   # Node.js bridge  
./nd-mcp.py ws://localhost:19999/mcp   # Python bridge

# You should see:
# nd-mcp: Connecting to ws://localhost:19999/mcp...
# nd-mcp: Connected
# Press Ctrl+C to stop the test

# Get the absolute path for your AI client configuration
pwd  # Shows current directory
# Example output: /home/user/netdata/src/web/mcp/bridges/stdio-golang
# Your nd-mcp path would be: /home/user/netdata/src/web/mcp/bridges/stdio-golang/nd-mcp

Important: When configuring your AI client, use the full absolute path to the executable:

Go bridge: /path/to/bridges/stdio-golang/nd-mcp
Node.js bridge: /path/to/bridges/stdio-nodejs/nd-mcp.js
Python bridge: /path/to/bridges/stdio-python/nd-mcp.py

Verify the Bridge Works

Once you have nd-mcp (either from existing installation or built), test it:

# Test connection to your Netdata instance (replace YOUR_NETDATA_IP with actual IP)
/path/to/nd-mcp ws://YOUR_NETDATA_IP:19999/mcp

# You should see:
# nd-mcp: Connecting to ws://YOUR_NETDATA_IP:19999/mcp...
# nd-mcp: Connected
# Press Ctrl+C to stop the test

Using MCP Remote Client

The official MCP remote client (mcp-remote) is an alternative bridge that enables stdio-only AI clients to connect to Netdata's HTTP and SSE transports (requires Netdata v2.7.2+). Unlike nd-mcp which only supports WebSocket, mcp-remote provides broader transport compatibility.

When to Use MCP Remote

Use mcp-remote when:

Your AI client only supports stdio communication
You want to use HTTP or SSE transports instead of WebSocket
You're running Netdata v2.7.2 or later
You don't want to build/install nd-mcp

Installation

No installation required - mcp-remote runs via npx:

# Test the connection
npx mcp-remote@latest --http http://YOUR_NETDATA_IP:19999/mcp \
  --allow-http \
  --header "Authorization: Bearer YOUR_API_KEY"

Transport Options

mcp-remote supports multiple transport strategies:

# HTTP transport (recommended)
npx mcp-remote@latest --http http://YOUR_NETDATA_IP:19999/mcp \
  --allow-http \
  --header "Authorization: Bearer YOUR_API_KEY"

# SSE transport
npx mcp-remote@latest --sse http://YOUR_NETDATA_IP:19999/mcp \
  --allow-http \
  --header "Authorization: Bearer YOUR_API_KEY"

# Auto-detect with fallback (tries SSE first, falls back to HTTP)
npx mcp-remote@latest --transport sse-first http://YOUR_NETDATA_IP:19999/mcp \
  --allow-http \
  --header "Authorization: Bearer YOUR_API_KEY"

# HTTPS (no --allow-http flag needed)
npx mcp-remote@latest --http https://YOUR_NETDATA_IP:19999/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"

Common Options

Option	Description	Example
`--http`	Use HTTP transport	`--http http://host:19999/mcp`
`--sse`	Use SSE transport	`--sse http://host:19999/mcp`
`--allow-http`	Allow non-HTTPS connections (required for HTTP URLs)	`--allow-http`
`--header`	Add custom headers (for authentication)	`--header "Authorization: Bearer KEY"`
`--transport`	Transport strategy	`--transport sse-first` (tries SSE, falls back to HTTP)
`--debug`	Enable debug logging	`--debug`
`--host`	OAuth callback host (default: localhost)	`--host 127.0.0.1`
Port number	OAuth callback port (optional)	`9696`

Authentication

For Netdata MCP, pass the API key via the Authorization header:

# Using environment variable (recommended)
export NETDATA_MCP_API_KEY="$(cat /var/lib/netdata/mcp_dev_preview_api_key)"

npx mcp-remote@latest --http http://YOUR_NETDATA_IP:19999/mcp \
  --allow-http \
  --header "Authorization: Bearer $NETDATA_MCP_API_KEY"

Security Note: The --allow-http flag is required for non-HTTPS connections. Only use this on trusted networks as traffic will not be encrypted.

Troubleshooting

Connection Issues:

# Enable debug logging
npx mcp-remote@latest --debug --http http://YOUR_NETDATA_IP:19999/mcp \
  --allow-http \
  --header "Authorization: Bearer YOUR_API_KEY"

# Check debug logs (stored in ~/.mcp-auth/)
cat ~/.mcp-auth/*_debug.log

Clear Authentication State:

# Remove cached credentials
rm -rf ~/.mcp-auth

Spaces in Arguments:

Some AI clients (Cursor, Claude Desktop on Windows) have issues with spaces in arguments. Use environment variables as a workaround:

{
  "mcpServers": {
    "netdata": {
      "command": "npx",
      "args": [
        "mcp-remote@latest",
        "--http",
        "http://YOUR_IP:19999/mcp",
        "--allow-http",
        "--header",
        "Authorization: Bearer YOUR_API_KEY"
      ]
    }
  }
}

Version Management

Always use the latest version:

# Force npx to check for latest version
npx mcp-remote@latest --http http://YOUR_NETDATA_IP:19999/mcp

Or in AI client configurations:

{
  "args": ["mcp-remote@latest", "--http", "..."]
}

For more details, see the official mcp-remote documentation.

Finding Your API Key

To access sensitive functions like logs and live system information, you need an API key. Netdata automatically generates an API key on startup. The key is stored in a file on the Netdata server you want to connect to.

You need the API key of the Netdata you will connect to (usually a Netdata Parent).

Note: This temporary API key mechanism will eventually be replaced by integration with Netdata Cloud.

Find the API Key File

# Try the default location first:
sudo cat /var/lib/netdata/mcp_dev_preview_api_key

# For static installations:
sudo cat /opt/netdata/var/lib/netdata/mcp_dev_preview_api_key

# If not found, search for it:
sudo find / -name "mcp_dev_preview_api_key" 2>/dev/null

Copy the API Key

The file contains a UUID that looks like:

a1b2c3d4-e5f6-7890-abcd-ef1234567890

Copy this entire string - you'll need it for your AI client configuration.

No API Key File?

If the file doesn't exist:

Ensure you have a recent version of Netdata
Restart Netdata: sudo systemctl restart netdata
Check the file again after restart

AI Client Configuration

AI clients can connect to Netdata MCP in different ways depending on their transport support:

Direct Connection (HTTP/SSE)

For AI clients that support HTTP or SSE transports:

{
  "mcpServers": {
    "netdata": {
      "type": "http",
      "url": "http://IP_OF_YOUR_NETDATA:19999/mcp",
      "headers": [
        "Authorization: Bearer YOUR_API_KEY"
      ]
    }
  }
}

Or for SSE:

{
  "mcpServers": {
    "netdata": {
      "type": "sse",
      "url": "http://IP_OF_YOUR_NETDATA:19999/mcp?transport=sse",
      "headers": [
        "Authorization: Bearer YOUR_API_KEY"
      ]
    }
  }
}

Using nd-mcp Bridge (stdio)

For AI clients that only support stdio:

{
  "mcpServers": {
    "netdata": {
      "command": "/usr/sbin/nd-mcp",
      "args": [
        "--bearer",
        "YOUR_API_KEY",
        "ws://IP_OF_YOUR_NETDATA:19999/mcp"
      ]
    }
  }
}

Using Official MCP Remote Client

{
  "mcpServers": {
    "netdata": {
      "command": "npx",
      "args": [
        "mcp-remote@latest",
        "--http",
        "http://IP_OF_YOUR_NETDATA:19999/mcp",
        "--header",
        "Authorization: Bearer YOUR_API_KEY"
      ]
    }
  }
}

Replace:

IP_OF_YOUR_NETDATA: Your Netdata instance IP/hostname
YOUR_API_KEY: The API key from the file mentioned above
/usr/sbin/nd-mcp: With your actual nd-mcp path (if using the bridge)

Multiple MCP Servers

You can configure multiple Netdata instances:

{
  "mcpServers": {
    "netdata-production": {
      "command": "/usr/sbin/nd-mcp",
      "args": ["--bearer", "PROD_KEY", "ws://prod-parent:19999/mcp"]
    },
    "netdata-testing": {
      "command": "/usr/sbin/nd-mcp",
      "args": ["--bearer", "TEST_KEY", "ws://test-parent:19999/mcp"]
    }
  }
}

Legacy Query String Support

For compatibility with older tooling, Netdata still accepts the ?api_key=YOUR_API_KEY query parameter on the /mcp endpoints. New integrations should prefer the Authorization: Bearer YOUR_API_KEY header, but the query-string form remains available if you are migrating gradually.
