CyberChef-MCP vs SchemaPin

CyberChef-MCP: CyberChef-MCP wraps the CyberChef Node.js API in a Model Context Protocol server so AI assistants can use CyberChef's data manipulation operations as executable tools. It is a fork that tracks the upstream GCHQ project.; SchemaPin: SchemaPin enables tool developers to sign schemas and skill folders with ECDSA P-256 keys, and AI agents to verify schema integrity. Public keys are discovered via .well-known/schemapin.json, and Trust-On-First-Use pinning prevents key substitution. It supports key revocation, trust bundles, and multiple languages (Python, JS, Go, Rust).
