"CyberChef MCP server by noorneitzen, a pentesting tool" matching MCP servers:

Enables LLM clients to encode, decode, and transform data using CyberChef operations via an MCP server that interfaces with the CyberChef API.

Exposes hundreds of CyberChef data operations as tools for LLM agents to perform encoding, decoding, hashing, compression, encryption, and data format conversion.

GCHQ CyberChef's 504 data-transformation operations as MCP tools — encryption, encoding, compression and forensics — w/ 19 analysis tools for work a single operation cannot express, such as: hash identification, RSA and ECDSA attacks, XOR key-length recovery, cipher solving, X.509 chain validation and NIST post-quantum identification (ML-KEM/ML-DSA/SLH-DSA).

Semantic navigator for MCP tools that finds relevant tools by natural language intent, reducing token usage by 95%.

An MCP server that provides utility tools for text analysis, URL metadata fetching, and temperature conversion.

A Model Context Protocol server that provides a scratchpad tool for LLMs to organize thoughts, take notes, and plan approaches to complex problems.

A tool discovery MCP server that integrates with Azure DevOps wikis and code-graph-rag to match natural language goals to tools, enabling tool composition and proxy testing.

An MCP server implementation of Anthropic's Think Tool prompt engineering technique that enables Claude to break down complex problems and enhance its reasoning capabilities by providing a simple tool that echoes back thoughts.

MCP server enabling Claude Code to capture screenshots of Windows applications through WSL2, allowing AI to diagnose UI errors and verify layouts.
