CyberChef API MCP Server: Bring Data Transformation Power to Your AI Conversations

Stop switching between your AI assistant and CyberChef's web interface. This MCP server puts CyberChef's entire arsenal of 300+ data transformation operations directly into your AI conversations.

The Problem Every Developer Knows

You're deep in a security analysis or data investigation. Your AI assistant identifies that some data needs decoding, but now you have to:

1. Copy the data
2. Open CyberChef in another tab
3. Build the recipe manually
4. Copy results back
5. Lose context in your AI conversation

That context switching kills momentum, especially when you're chaining multiple operations or working with complex data transformations.

What This Changes

With the CyberChef API MCP Server, your AI assistant becomes a data transformation powerhouse. Ask it to decode Base64, decrypt AES, analyze file formats, or build complex transformation pipelines - all without leaving the conversation.

Real example: "Decode this base64, then decompress with gzip, then extract the JSON and tell me what API endpoints it contains." Done in one request, with full context maintained.

Key Capabilities

Complete Operation Access: Every CyberChef operation category - from basic encoding to advanced cryptography - available through natural language requests.

Magic Operations: Let CyberChef automatically detect encoding and suggest transformation paths. Perfect when you're not sure what you're looking at.

Batch Processing: Transform multiple inputs simultaneously instead of processing them one by one.

Recipe Chaining: Build complex multi-step transformations that would take several manual operations in the GUI.

Perfect For

Security Researchers: Analyze malware samples, decode obfuscated payloads, and investigate suspicious data without workflow interruption.

CTF Players: Rapid-fire encoding challenges become conversations instead of manual puzzle-solving sessions.

Data Engineers: Transform and analyze data formats on the fly during exploratory analysis.

Incident Response: Quickly decode and analyze suspicious artifacts during investigations.

Integration in Minutes

The server connects to any running CyberChef instance and exposes five core functions through MCP:

• bake_recipe - Execute transformation recipes on single inputs
• batch_bake_recipe - Process multiple inputs with the same recipe
• perform_magic_operation - Auto-detect and suggest transformations
• get_cyberchef_operations_categories - Browse available operation categories
• get_cyberchef_operation_by_category - Explore specific operation sets

Set your CyberChef API URL, add the server to your MCP client configuration, and you're ready to transform data through conversation.

Why This Matters

Data transformation shouldn't break your analytical flow. When your AI assistant can decode that suspicious string, decrypt that configuration file, or analyze that binary blob without you switching tools, you stay in the zone where insights happen.

The power of CyberChef's battle-tested operations, accessible through the natural language interface you're already using for analysis. That's workflow optimization that actually moves the needle.

Ready to stop context-switching your way through data analysis? This MCP server turns your AI assistant into a data transformation expert that never breaks your concentration.
