- Logs connection attempts, HTTP/HTTPS requests, and DNS lookups
- Writes logs to console and optionally to a JSON file
- Runs your MCP server within a monitored environment
- Uses Node.js module interception transparently
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
MCP Network SentinelCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Install the package globally with npm install -g @takeaship/mcp-network-sentinel, then run it by wrapping your MCP server command in the sentinel: npx @takeaship/mcp-network-sentinel "your-mcp-server-package arg1 arg2" --output=network-logs.json. The --output (or -o) flag is optional and saves logs to a specified JSON file.

}MCP Network Sentinel
A network monitoring tool for MCP servers that logs all network activities to help identify potential security issues.
Background
When using third-party MCP servers to access confidential data, there's a risk that the MCP server might transmit your data or access keys to external sources. This tool monitors all network communications from the MCP server to help identify any suspicious activities.
Installation
npm install -g @takeaship/mcp-network-sentinel
Usage
npx @takeaship/mcp-network-sentinel "your-mcp-server-package arg1 arg2" --output=network-logs.json
Features
- Monitors all network activity from MCP servers
- Logs connection attempts, HTTP/HTTPS requests, and DNS lookups
- Writes logs to console and optionally to a JSON file
- Runs your MCP server within a monitored environment
How It Works
MCP Network Sentinel uses Node.js module interception to hook into the network-related modules and log all outgoing connections. It works by:
1. Intercepting calls to network modules (net, tls, http, https, dns)
2. Logging connection details including destination, port, and protocol
3. Running your MCP server command in a monitored environment
4. Saving logs to a JSON file if specified
Options
- -o, --output <file> - Save network logs to a specified JSON file
