CipherHUB Cryptography Toolkit is answering right now. Last checked 14 min ago. It exposes 55 tools. Last commit 30 Apr 2026.
Production-grade cryptography toolkit with 31 MCP tools for classical, PQC, and KMS workflows.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 2 September 2026. No other catalogue keeps this.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
