CyberChef MCP server

This is a helper for your AI that handles the fiddly code-and-cipher jobs: decoding scrambled text, checking password hashes, reading login tokens, and spotting things like card numbers in a block of text. It is handy if you work in security, IT support, or just keep getting odd-looking strings you cannot read. You ask in normal words, and it does the decoding for you.

What this MCP server does

You paste something that looks like gibberish, or a token, or a hash, and ask your AI what it is. Your AI passes it to this helper. The helper runs the decoding or checking steps in order, like peeling layers off an onion, and works out what the original text was. Then it sends a short, tidy result back, and your AI explains it to you in the chat. It can also do the reverse and scramble text back into coded form when you need that.

What you can do with it

• Decode scrambled text that has several layers of encoding stacked on top of each other
• Work out an unknown encoding automatically when you do not know where to start
• Read a login token and show you what is inside it and when it expires
• Measure how random a chunk of text looks, which hints at whether it is encrypted or packed
• Identify what kind of password hash you are looking at and its settings
• Find and hide sensitive details like card numbers, social security numbers and email addresses in a block of text
• Make a dangerous web link safe to share by breaking it so nobody can click it by accident
• Encode or decode text between plain, hex and Base64 forms

Try asking your AI

• “This string looks scrambled, can you work out what it says: SGVsbG8gV29ybGQ=”
• “Decode this login token and tell me when it expires”
• “What kind of password hash is this and is it a strong setting”
• “Check this paragraph for card numbers and email addresses and hide them”
• “Make this link safe to paste into a report”

What it gives back to you

You get a short answer in the chat, not a file. Depending on what you asked, that might be the decoded text, a list of the pieces found inside a token, a number for how random the text looks, or the same text with sensitive parts blanked out. If it changed or scrambled something, it shows you the new version so you can copy it.
