Kryptheon

Overview

Kryptheon is a Model Context Protocol server that lets you record flows through your application, verify them after every change, and test against a copy of your database. By exposing these capabilities as MCP tools, it enables AI assistants to work directly with your testing and attack surface without manual context switching.

The server runs locally on your machine via the npm package kryptheon-mcp, which communicates with MCP clients over stdio. It requires an API Key for authentication and is currently at version v0.1.1. Install it with npx -y kryptheon-mcp.

Kryptheon is listed in the Database category on mcp.site and works with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim this listing to earn the Verified badge and ensure the information stays accurate.
