About Signs of AI Writing

Signs of AI Writing is an MCP server published by the GitHub account peopleworks. AI-writing detection (EN/ES) that shows the evidence: named tells, hidden characters, citations.

It runs on your own machine: your AI client starts it from the NuGet package SignsOfAI.Mcp at version 0.8.1.

It asks for no keys or passwords.

Version 0.8.1 was published on 16 September 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 0 warn, 0 fail, 3 info. How we check.
