Markdown Content: Netdata Model Context Protocol (MCP) Integration

Netdata Agents (and soon Netdata Cloud) provide a Model Context Protocol (MCP) server that enables AI assistants like Claude or Cursos to interact with your infrastructure monitoring data. This integration allows AI assistants to access metrics, logs, alerts, and live system information (processes, services, containers, VMs, network connections, etc), acting as a capable DevOps/SRE/SysAdmin assistant.

Overview

The AI assistants have different visibility on your infrastructure, depending on where in a Netdata hierarchy they are connected:

• Netdata Cloud: (not yet available) AI assistants connected to Netdata Cloud will have full visibility across all nodes in your infrastructure.
• Netdata Parent Node: AI assistants connected to a Netdata parent node will have visibility across all child nodes connected to that parent.
• Netdata Child Node: AI assistants connected to a Netdata child node will only have visibility into that specific node.
• Netdata Standalone Node: AI assistants connected to a standalone Netdata node will only have visibility into that specific node.

Supported AI Assistants

You can use Netdata with the following AI assistants:

• Claude Desktop: supports flat-fee usage for unlimited access
• Claude Code: supports flat-fee usage for unlimited access
• Cursor: supports flat-fee usage for unlimited access. Enables Netdata use with multiple AI assistants, including Claude, ChatGPT, and Gemini.

Probably more: Check the MCP documentation for a full list of supported AI assistants.

All these AI assistants need local access to the MCP servers. This means that the application you run locally on your computer (Claude Desktop, Cursor, etc) needs to be able to connect to the Netdata using stdio communication. However, since your Netdata runs remotely on a server, you need a bridge to convert the stdio communication to WebSocket communication. Netdata provides bridges in multiple languages (Node.js, Python, Go) to facilitate this.

Once MCP is integrated into Netdata Cloud, Web-based AI assistants will also be supported. For Web-based AI assistants, the backend of the assistant connects to a publicly accessible MCP server (i.e. Netdata Cloud) to access infrastructure observability data, without needing a bridge.

Installation

The MCP server is built into Netdata and requires no additional installation. Just ensure you have a recent version of Netdata installed.

To use the MCP integration of Netdata with AI clients, you need to configure them and bridge them to the Netdata MCP server.

Configuration of AI Assistants

The configuration of most AI assistants is done via a configuration file, which is almost identical for all of them.

{ "mcpServers": { "netdata": { "command": "/usr/bin/nd-mcp", "args": [ "ws://IP_OF_YOUR_NETDATA:19999/mcp?api_key=YOUR_API_KEY" ] } } }

The program nd-mcp is the bridge program that converts stdio communication to WebSocket communication. This program is part of all Netdata installations, so by installing Netdata on your personal computer (Linux, MacOS, Windows) you will have it available.

There may be different paths for it, depending on how you installed Netdata:

• /usr/bin/nd-mcp or /usr/sbin/nd-mcp: Linux native packages (together with the netdata and netdatacli commands)
• /opt/netdata/usr/bin/nd-mcp: Linux static Netdata installations
• /usr/local/netdata/usr/bin/nd-mcp: MacOS installations from source
• C:\\\\Program Files\\\\Netdata\\\\usr\\\\bin\\\\nd-mcp.exe: Windows installations

You will also need:

IP_OF_YOUR_NETDATA, is the IP address or hostname of the Netdata instance you want to connect to. This will eventually be replaced by the Netdata Cloud URL. For this dev preview, use any Netdata, preferably one of your parent nodes. Remember that the AI assistant will "see" only the nodes that are connected to that Netdata instance.

YOUR_API_KEY is the API key that allows the AI assistant to access sensitive functions like logs and live system information. Just start Netdata and it will automatically generate a random UUID for you. You can find it at:

/var/lib/netdata/mcp_dev_preview_api_key

or, if you installed a static Netdata package, it may be located at:

/opt/netdata/var/lib/netdata/mcp_dev_preview_api_key

To view your API key:

sudo cat /var/lib/netdata/mcp_dev_preview_api_key

or

sudo cat /opt/netdata/var/lib/netdata/mcp_dev_preview_api_key

Claude Desktop

To add Netdata MCP to Claude Desktop:

1. Open Claude Desktop
2. Navigate to the Developer settings:

• Windows/Linux: File → Settings → Developer (or use Ctrl+,)
• macOS: Claude → Settings → Developer (or use Cmd+,)

1. Click the "Edit Config" button (below the server list)
2. This will open or show the exact configuration file location
3. Add the configuration mentioned above to that file.

Linux Users: Claude Desktop is available via a community project (https://github.com/fsoft72/claude-desktop-to-appimage). It works best with https://github.com/TheAssassin/AppImageLauncher.

Once configured correctly, you will need to restart Claude Desktop. Once restarted, you should see "netdata" appear in Claude Desktop:

• Click the "Search and tools" button (just below the prompt)
• You should see "netdata" listed among the available tools
• If you don't see it, check your configuration and ensure the bridge is accessible

Claude Code

For Claude Code, add to your project's root, the file .mcp.json, with the contents given above. This file will be automatically detected by Claude Code the next time it starts in that directory.

Alternatively, you can add it using a Claude CLI command like this:

claude mcp add netdata /usr/bin/nd-mcp ws://IP_OF_YOUR_NETDATA:19999/mcp?api_key=YOUR_API_KEY

Once configured correctly, run claude mcp list or you can issue the command /mcp to your Claude Code. It should show you the available MCP servers, including "netdata".

Cursor

For Cursor, add the configuration to the MCP settings.

Alternative stdio to websocket Bridges

We provide 3 different bridges for you to choose the one that best fits your environment:

1. Go bridge: Located at src/web/mcp/bridges/stdio-golang/
2. Node.js bridge: Located at src/web/mcp/bridges/stdio-nodejs/
3. Python bridge: Located at src/web/mcp/bridges/stdio-python/

All these bridges should provide exactly the same functionality, so you can choose the one that best fits your environment.

Each of these directories includes build.sh script to install dependencies and prepare the bridge. The Go bridge provides also a build.bat script for Windows users.

For example, Claude promises that your data will not be used to train their models for certain subscriptions, and Cursor allows you to use multiple AI assistants. Always check the privacy policies of the AI assistant you choose.

• Q: Are the responses of AI assistants accurate?

  • A: AI assistants like Claude are designed to provide accurate and relevant responses based on the data they have access to. However, they may not always be perfect, or they may have not checked all the aspects before giving answers. It's important to verify critical information.

Best Practices

AI Assistants sampling data

Sometimes, when you ask generic questions about your infrastructure, AI assistants do a simple sampling on a few nodes of the infrastructure, instead of querying all nodes. In Netdata we have provided the tools to properly do that, but AI assistants may not use them.

Examples:

Q: "which are the top processes/containers/VMs/services running on my servers?"

The AI assistant may respond with a list of processes/containers/VMs/services from a few nodes, instead of querying all nodes.

The proper way in Netdata is to query:

• app.* charts/contexts for processes, which will return the processes running on all nodes grouped by category.
• systemd.* to get the services running on all nodes.
• cgroup.* to get the all the containers and VMs on all nodes.

For all such queries, Netdata responses return cardinality information (much like the NIDL charts on your Netdata dashboard), so the AI assistant could get a much better picture instead of sampling data. When you notice that, you could ask the AI assistant to find the answer using more generic queries.

AI Assistants missing newer Netdata features

Sometimes you ask AI assistants about features that have been recently added to Netdata (eg logs, or windows capabilities), and the AI assistant instead of checking what is available via their MCP connection, they say that Netdata does not support that feature. Answering "check your MCP tools, features, functions" is usually enough for the AI assistant to check the available features and start using them.

AI Assistants not using MCP at all

Sometimes you need instruct them to use their MCP connection. So instead of saying "check the performance of my production db", you can say "use netdata to check the performance of my production db". This way, the AI assistant will use its MCP connection to query the Netdata instance and provide you with the relevant information.

Use AI Assistants to do your DevOps/SRE/SysAdmin "laundry"

Our advice is to use AI assistants to do "your laundry": Give them specific tasks, check the queries they did to get that information, and when possible ask them to cross-check their answers using a different tool/source. AI assistants usually rush to make conclusions, so challenge them and they will go deeper and correct themselves. Remember that you always need to verify their answers, especially for critical tasks.

Multiple Netdata MCP servers for a single AI assistant

If you need to configure multiple MCP servers, you can add them under the mcpServers section with different names. Example:

{ "mcpServers": { "netdata-production": { "command": "/usr/bin/nd-mcp", "args": [ "ws://IP_OF_YOUR_NETDATA:19999/mcp?api_key=YOUR_API_KEY" ] }, "netdata-testing": { "command": "/usr/bin/nd-mcp", "args": [ "ws://IP_OF_YOUR_NETDATA:19999/mcp?api_key=YOUR_API_KEY" ] } } }

However, when multiple netdata MCP servers are configured, all AI assistants have difficulties to determine which one to use:

• Claude Desktop: it seems there is no way to instruct it to use the right one. There is an enable/disable toggle for each MCP server, which however does not work properly. So, it is best to configure only one MCP server at a time.
• Cursor: Similarly, it is impossible to instruct it to use the right one. However, there is a toggle and it works properly, but you still need to ensure that the Netdata server you want to use is the only one enabled.
• Claude Code: this project has a different philosophy: you can have a different .mcp.json file in each project directory (the current directory from which you run it), so you can have different configurations for each project/directory. Since Claude Code also supports a Claude.md file with default instructions to the AI assistant, you can have different directories with different instructions and configurations, so you can use multiple Netdata MCP servers by spawning multiple Claude Code instances in different directories.
