CyberChef API MCP Server

If you already use CyberChef API, the cyberchef api mcp server is the piece that lets your assistant work with it directly. CyberChef API MCP Server ✨🧑‍🍳.

What the server does

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.

Installation

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

• 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

Credentials and setup notes

Configuration is passed through the environment: CYBERCHEF_API_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Worth knowing first

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. CyberChef API's toolset — get_cyberchef_operations_categories, get_cyberchef_operation_by_category, bake_recipe and 2 more — is a fair guide to whether it matches your workflow. It is maintained by slouchd; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
