Add to your MCP client's JSON config.

This is third-party code. Review the repository files before installing.

What it does

The server adds one scenario for the agent: send text to the GigaChat API and get an assessment of whether it looks AI generated. The check uses Sber's detection method rather than the agent model's own judgment. It is added as one MCP config entry via uvx and works in Cursor and other stdio clients.

Who it is for. Editors, teachers and HR staff at companies with corporate GigaChat API access.

Good fit when

  • You need to check a submitted text for machine generation
  • You want the check inside the agent workflow without a separate service

Not a fit when

  • You are on a personal plan without corporate access
  • The check result would be the only basis for a decision about a person

Example request

Check whether this student essay was generated by AI

Limitations

Generation detection is only available on corporate GigaChat API plans, and the config needs GIGACHAT_SCOPE set to GIGACHAT_API_CORP. Python 3.12 is required. The repository has not been updated since May 2025, and the PyPI package is published from the author's original repo trashchenkov/mcp_giga_checker. Any detector can be wrong, so treat results as a hint.

How to disable. Remove the mcp-giga-checker block from the MCP config or set enabled to false.
