A Model Context Protocol server implementation for NTOPNG that enables AI agents to query networks monitoring data using the NTOPNG database.

This MCP Server assumes that ntopng is using ClickHouse to store historical flows and alert. Check ntopng Clickhouse

Status

Works with Claude Desktop app and other MCP compliant hosts and clients.

No support for MCP resources or prompts yet.

Configuration

1. Create or edit the Claude Desktop configuration file located at:

   • On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • On Windows: %APPDATA%/Claude/claude_desktop_config.json

2. Add the following:

{
  "mcpServers": {
    "mcp-ntopng": {
      "command": "/path/to/your/uv-binary",
      "args": ["run", "--with", "mcp-ntopng", "--python", "3.13", "mcp-ntopng"]
      "env": {
        "NTOPNG_HOST": "<ntopng-host>",
        "NTOPNG_DBPORT": "<ntopng-dbport>",
        "NTOPNG_DBUSER": "<ntopng-dbuser>",
        "NTOPNG_DBPASSWORD": "<ntopng-dbpassword>",
        "NTOPNG_SECURE": "true",
        "NTOPNG_VERIFY": "true",
        "NTOPNG_CONNECT_TIMEOUT": "30",
        "NTOPNG_SEND_RECEIVE_TIMEOUT": "300",
        "NTOPNG_API_KEY": "NTOPNG_TOKEN"
      }
    }
  }
}

3. Replace /path/to/your/uv-binary with the absolute path to the uv executable. Find the path with which uv. This ensures that the correct version of uv is used when starting the server.

4. Restart Claude Desktop to apply the changes.

Development

1. Set the environmental variables either in the claude_desktop_config.json file or in a .env file in the root of the repository.

NTOPNG_HOST=localhost
NTOPNG_PORT=9000
NTOPNG_USER=default
NTOPNG_PASSWORD=

3. Run uv sync to install the dependencies. To install uv follow the instructions here. Then do source .venv/bin/activate.

4. Install the mcp-ntopng package with uv pip install -e . from the project main directory.

5. For easy testing, you can run mcp dev mcp_ntopng/mcp_server.py to start the MCP server. CHANGE WITH A PROPER CHAT CLIENT

Environment Variables

The following environment variables are used to configure the database connection:

• NTOPNG_HOST: The hostname of the ntopng server
• NTOPNG_DBUSER: The username for Clickhouse DB authentication
• NTOPNG_DBPASSWORD: The password for Clickhouse DB authentication
• NTOPNG_API_KEY: The ntopng authentication token.

Optional

• NTOPNG_DBPORT: The port number of the Clickhouse DB in the ntopng server
  • Default: 9000 if HTTPS is enabled, 8123 if disabled
  • Usually doesn't need to be set unless using a non-standard port
• NTOPNG_SECURE: Enable/disable a TLS connection
  • Default: false
  • Set to true for a secure TLS connections
• NTOPNG_VERIFY: Enable/disable SSL certificate verification
  • Default: true
  • Set to `false to disable certificate verification (not recommended for production)
• NTOPNG_CONNECT_TIMEOUT: Connection timeout in seconds
  • Default: `30
  • Increase this value if you experience connection timeouts
• NTOPNG_SEND_RECEIVE_TIMEOUT: Send/receive timeout in seconds
  • Default: 300
  • Increase this value for long-running queries

Check TLS Setup in the ntopng documentation for details about setting up a TLS connection to Clickhouse.

Development

Install the package on the local machine:

$ uv sync
$ uv pip install -e .

Run the MCP Inspector

$ cd mcp_ntopng
$ source .env
$ CLIENT_PORT=8077 SERVER_PORT=8078  mcp dev run_mcp_ntopng.py --with clickhouse-driver --with python-dotenv --with uvicorn --with pip-system-certs

Use the local library in Claude Desktop.

Find: /Users/marco/Library/Application\ Support/Claude/claude_desktop_config.json

Edit the claude_desktop_config.json changing the local paths:
