WireMCP is a Model Context Protocol (MCP) server that enhances Large Language Models with network traffic analysis capabilities. It captures and processes live network data using Wireshark's tshark, providing structured information that helps LLMs perform tasks like threat hunting, network diagnostics, and anomaly detection.
Before installing WireMCP, ensure you have:
tshark
installed and accessible in PATHgit clone https://github.com/0xkoda/WireMCP.git
cd WireMCP
npm install
node index.js
Note: WireMCP will automatically detect tshark or fall back to common install locations (such as /Applications/Wireshark.app/Contents/MacOS/tshark
on macOS).
To use WireMCP with Cursor, edit the mcp.json
file in Cursor's settings:
{
"mcpServers": {
"wiremcp": {
"command": "node",
"args": [
"/ABSOLUTE_PATH_TO/WireMCP/index.js"
]
}
}
}
On macOS, this configuration file is typically located at /Users/YOUR_USER/Library/Application Support/Claude/claude_desktop_config.json
.
WireMCP works with any MCP-compliant client. Simply configure the client to use the command node /path/to/WireMCP/index.js
.
WireMCP provides several tools that LLMs can leverage:
Captured IPs:
174.67.0.227
52.196.136.253
Threat check against URLhaus blacklist:
No threats detected in URLhaus blacklist.

To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "wiremcp" '{"command":"node","args":["/ABSOLUTE_PATH_TO/WireMCP/index.js"]}'
See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json
file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json
file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"wiremcp": {
"command": "node",
"args": [
"/ABSOLUTE_PATH_TO/WireMCP/index.js"
]
}
}
}
To add an MCP server to a project you can create a new .cursor/mcp.json
file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:
1. Find your configuration file:
~/Library/Application Support/Claude/claude_desktop_config.json
%APPDATA%\Claude\claude_desktop_config.json
~/.config/Claude/claude_desktop_config.json
2. Add this to your configuration file:
{
"mcpServers": {
"wiremcp": {
"command": "node",
"args": [
"/ABSOLUTE_PATH_TO/WireMCP/index.js"
]
}
}
}
3. Restart Claude Desktop for the changes to take effect
