Documentation Overview

CyberChef API MCP Server

This model context protocol (MCP) server interfaces with the CyberChef Server API. Allowing you to use any LLM/MCP client of your choosing to utilise the tools and resources within CyberChef.

🧰 Available Tools and Resources

get_cyberchef_operations_categories: resource - gets updated Cyber Chef categories for additional context / selection of the correct operations
get_cyberchef_operation_by_category: resource - gets list of Cyber Chef operations for a selected category
bake_recipe: tool - bake (execute) a recipe (a list of operations) in order to derive an outcome from the input data
batch_bake_recipe: tool - bake (execute) a recipe (a list of operations) in order to derive an outcome from a batch of input data
perform_magic_operation: tool - perform CyberChef's magic operation which is designed to automatically detect how your data is encoded and which operations can be used to decode it

📝 Usage

Start the server using the default stdio transport and specifying an environment variable pointing to a CyberChef API

bash

CYBERCHEF_API_URL="your-cyberchef-api-url" uv run cyberchef_api_mcp_server

🧑‍💻Usage (Development)

Start the server and test it with the MCP inspector

bash

uv add "mcp[cli]"
mcp dev server.py

📚 Client Configuration

The following commands will generate a client configuration file, the location will depend on your operating system

bash

uv add "mcp[cli]"
mcp install server.py --name "CyberChef API MCP Server"

[!TIP] After running the above command you can then tweak the client configuration to include the environment variable for the CyberChef API URL

config.json
