# CyberChef

> Use this tool when you need to perform cryptographic, encoding, compression, and data analysis operations, such as Base64 encoding or AES decryption, to aid in cybersecurity analysis, data transformation workflows, and forensic investigations. It provides over 300 individual tools and a meta-tool for executing complex multi-step recipes, making it a valuable resource for AI agents. With a dynamic interface generating tool schemas from operation configurations, CyberChef-MCP streamlines access to specialized encoding and cryptographic functions.

## Description

CyberChef-MCP converts the popular CyberChef web application into an MCP server, exposing over 300 cryptographic, encoding, compression, and data analysis operations as individual tools for AI agents. Built by doublegate using Node.js and the MCP SDK, it wraps CyberChef's existing Node.js API to provide both atomic operations (like Base64 encoding or AES decryption) and a meta-tool for executing complex multi-step recipes. The Docker-based implementation includes patches for Node.js v22 compatibility and dynamically generates tool schemas from CyberChef's operation configuration, making it valuable for cybersecurity analysis, data transformation workflows, and forensic investigations where AI agents need access to specialized encoding and cryptographic functions.
