<div align="center"> A <strong>stand-alone MCP server</strong> built with <a href="https://github.com/modelcontextprotocol/fastmcp"><strong>FastMCP</strong></a> that exposes key functionalities of the <a href="https://radkit.cisco.com/"><strong>Cisco RADKit</strong></a> SDK as MCP tools.
</br>It is designed to be connected to any <strong>MCP client</strong> and <strong>LLM</strong> of your choice, enabling intelligent interaction with network devices through Cisco RADKit. <br /><br /> </div>

Disclaimer: This MCP Server is not an official Cisco product. It was developed for experimentation and learning purposes.

🚀 Overview

This MCP server acts as a lightweight middleware layer between the Cisco RADKit service and an MCP-compatible client.
It allows the LLM to inspect and interact with devices onboarded in the RADKit inventory, fetch device attributes, and even execute CLI commands — all through structured MCP tools.

⚙️ Features

• 🔌 Plug-and-play MCP server — works with any MCP-compatible client.
• 🔍 Inventory discovery — list all onboarded network devices.
• 🧠 Device introspection — fetch device attributes and capabilities.
• 🖥️ Command execution — run CLI commands on network devices.
• 📦 Fully type-hinted tools for clarity and extensibility.

📚 Included libraries

All required libraries are mentioned in the file requirements.txt, including their fixed versions.

• cisco_radkit_client==1.9.0
• cisco_radkit_common==1.9.0
• cisco_radkit_service==1.9.0
• fastmcp==2.13.1

🧰 Exposed MCP Tools

Tool Name	Description	Inputs	Returns	Use Case
get_device_inventory_names()	Returns a string containing the names of devices onboarded in the Cisco RADKit inventory.	None	str: List of onboarded devices (e.g. {"p0-2e", "p1-2e"})	Use this first when the user asks about "devices", "network", or "all devices".
get_device_attributes(target_device: str)	Returns detailed information about a specific device in JSON format.	target_device (str): Target device name.	str: JSON with attributes including name, host, type, configs, SNMP/NETCONF status, capabilities, etc.	Use this when the user asks about a specific device.
exec_cli_commands_in_device(target_device: str, cli_command: str)	Executes a CLI command or commands on a target device and returns the raw text result.	target_device (str): Device name.<br>cli_commands ([str]): CLI command or commands to execute.	str: Raw output of the executed command.	Use this only if info is unavailable in get_device_attributes() or when explicitly asked to “run” or “execute” a command.

🧩 Requirements

• Python 3.10+
• Active Cisco RADKit service
• At least one read-only/RW user onboarded in the Cisco RADKit service

🛠️ Installation

Clone the repository in your deployment environment.

git clone https://github.com/ponchotitlan/radkit-mcp-server.git
cd radkit-mcp-server

⚙️ Setup

Execute the included assistant script in a terminal based on your type of host OS:

🐧🍎 Linux/MacOS:

chmod +x setup.sh

bash setup.sh

🪟 Windows:

setup.bat

The assistant will first create a virtual environment folder radkit-mcp-server/.venv/ with all the python libraries required. Afterwards, it will trigger the following assistant:

   Exit

👾 1. Non-interactive Cisco RADKit authentication setup

The MCP server makes use of certificate login to avoid asking for Web UI authentication every time a tool is used. For that, the certificates need to be generated in the host. Select the first option and follow the instructions.

This MCP server supports both stdio and https transport methods. When prompted, choose the one that you would like to use:

? Select MCP transport mode: (Use arrow keys)
 » stdio
   https

Default choice is stdio. Otherwise, if https is selected, you will be prompted for the following information:

? Select MCP transport mode: https
? Enter MCP host: 0.0.0.0
? Enter MCP port: 8000

The file radkit-mcp-server/.env is generated with environment variables that the MCP Server needs.</br></br> ✅ Your MCP server is ready for use!

⚡️ Usage example: Claude Desktop

The Claude Desktop application provides an environment which integrates the Claude LLM and a rich MCP Client compatible with this MCP Server.

To get started, download the Claude Desktop app for your host OS, and choose the LLM usage plan that best fits your needs.

Afterwards, edit the radkit-mcp-server/claude_desktop_config.json file included in this repository to point to the absolute paths of your .venv and mcp_server.py files:

{
  "mcpServers": {
    "radkit-mcp-server": {
      "command": "/Users/ponchotitlan/Documents/radkit-mcp-server-community/.venv/bin/python",
      "args": [
        "/Users/ponchotitlan/Documents/radkit-mcp-server-community/mcp_server.py"
      ],
      "description": "Cisco RADKit MCP Server - Community"
    }
  }
}

Then, copy this file to the location of your Claude Desktop application' configurations. The directory varies depending on your host OS:

🍎 MacOS:

cp claude_desktop_config.json ~/Library/Application\ Support/Claude 

🪟 Windows:

cp claude_desktop_config.json %APPDATA%\Claude\

🐧 Linux:

cp claude_desktop_config.json ~/.config/Claude/

Now, restart your Claude Desktop app. Afterwards, if you navigate to Configurations/Developer/, you should see the MCP Server up and running:

✨ Prompt examples

📚 Show the inventory of your Cisco RADKit service</br> One of the MCP server tools provides a list of device names. <div align="center"> <img src="images/radkit_mcp_demo_1_inventory.gif"/> </div>

</br>🎰 Ask specific questions about a device</br> Another MCP server tool provides information of the device if available directly in the Cisco RADKit SDK. <div align="center"> <img src="images/radkit_demo_2_device_type.gif"/> </div>

</br>Otherwise, a command is executed in the device via a MCP server tool to get the information required. <div align="center"> <img src="images/radkit_demo_3_interfaces.gif"/> </div>

</br>🗺️ Complex querying using networking data</br> The LLM can use the information from multiple data network queries to build, for example, a topology diagram. <div align="center"> <img src="images/radkit_demo_4_topology.gif"/> </div>

</br>This diagram can be later refined with more information from the network as required. <div align="center"> <img src="images/radit_demo_5_enhanced_topology.gif"/> </div>

</br>⬇️ Push configurations</br> Not everything is query information! If the Cisco RADKit user onboarded in the MCP server is enabled with Write privileges, commit operations can take place. <div align="center"> <img src="images/radkit_demo_6_config_commit.gif"/> </div>

</br>These are just some examples of what can be done with this MCP server!
