Byakugan

Overview

Byakugan is a Model Context Protocol (MCP) server: Private, on-device AI-text analysis including detection, AI-tell spans, and reuse overlap. Because it speaks the Model Context Protocol, AI assistants can use Byakugan as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package @jayofemi/ai-checker speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v1.0.0, published under the MIT license, with source at JayOfemi/byakugan on GitHub.

On mcp.site, Byakugan sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
