How to Set Up and Use Cisco Packet Tracer
The Packet Tracer MCP server gives AI models direct control over Cisco Packet Tracer network simulations through 33 structured tools, enabling LLMs to plan, generate, validate, and deploy network topologies entirely through natural language. It covers everything from device catalog lookup and IOS CLI configuration generation to live deployment via a Packet Tracer HTTP bridge, ACL management, and NAT/PAT configuration — making it a powerful assistant for network engineering students and professionals alike.
Prerequisites
- Python 3.8 or higher installed
- Cisco Packet Tracer installed (required for live deployment tools; optional for topology generation and CLI config tools)
- Git to clone the repository
- An MCP-compatible client such as Claude Desktop or VS Code with the Copilot MCP extension
Clone the repository
Clone the MCP-Packet-Tracer repository from GitHub to your local machine.
git clone https://github.com/Mats2208/MCP-Packet-Tracer
cd MCP-Packet-TracerInstall the package in editable mode
Install the package using pip in editable mode so the packet_tracer_mcp module is available as a runnable Python module from any directory.
pip install -e .Verify the server starts
Run the server in stdio mode to confirm the install succeeded. You should see server startup output before it waits for MCP input.
python -m packet_tracer_mcp --stdioConfigure Claude Desktop
Add the server to your Claude Desktop configuration file. On macOS this is ~/Library/Application Support/Claude/claude_desktop_config.json.
{
"mcpServers": {
"packet-tracer": {
"command": "python",
"args": ["-m", "packet_tracer_mcp", "--stdio"]
}
}
}Restart Claude Desktop
Fully quit Claude Desktop (not just close the window) and reopen it. The packet-tracer server should appear in the MCP tools list.
Enable live deployment (optional)
For tools that interact with a running Packet Tracer instance, make sure Packet Tracer is open and the built-in HTTP bridge is enabled. The server connects to it automatically on the default port.
Cisco Packet Tracer Examples
Client configuration
Complete claude_desktop_config.json block for the Packet Tracer MCP server.
{
"mcpServers": {
"packet-tracer": {
"command": "python",
"args": ["-m", "packet_tracer_mcp", "--stdio"]
}
}
}Prompts to try
Example prompts you can send to Claude once the Packet Tracer MCP server is connected.
- "Generate a small office network with two switches, a router, and five PCs connected in a star topology."
- "Create IOS CLI configuration commands for enabling OSPF on all interfaces of Router0."
- "Validate my topology plan and list any errors."
- "List all supported Cisco router and switch models in the device catalog."
- "Add an ACL to Router1 that blocks traffic from 192.168.1.0/24 to 10.0.0.0/8."Troubleshooting Cisco Packet Tracer
python -m packet_tracer_mcp not found after pip install -e .
Ensure you ran 'pip install -e .' inside the cloned repository directory and that the same Python interpreter is used by Claude Desktop. Use an absolute path to the Python binary in the config if needed (e.g. '/usr/local/bin/python3').
Live deployment tools fail to connect to Packet Tracer
Open Cisco Packet Tracer and ensure the IPC (HTTP bridge) feature is enabled in its settings. The server connects on localhost; check that no firewall rule is blocking the port.
Claude Desktop does not show the packet-tracer server
Check that claude_desktop_config.json is valid JSON (no trailing commas, correct braces). On Windows with the Microsoft Store version, use the MSIX config path: %LOCALAPPDATA%\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\claude_desktop_config.json.
