Access and checks

How we review

Extended accessThe tool runs code or makes network calls and only reads external data.

  • Starts four Node servers that call YandexGPT, Vision, SpeechKit and search with Yandex Cloud keys
  • Yandex Cloud bills the calls, the servers do not change external accounts

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

What it does

A general-purpose version of the same collection as the author's openclaw-tools-collection, but not tied to a specific assistant. Four independent Node.js servers: yandexgpt-server provides YandexGPT text completion and chat, yandex-vision-server recognizes text and text blocks in images, yandex-speechkit-server synthesizes speech (voices alena, filipp, jane, omazh, zahar, ermil, marina) and recognizes short and long audio, and yandex-search-server searches the web, images and news via the aging Yandex Search XML API with a separate key.

Who it is for. For developers who want a simple starting example for connecting several Yandex Cloud services to an MCP client.

Good fit when

  • You want a minimal single-file server for YandexGPT, OCR or SpeechKit with no extra tooling
  • You already have Yandex Cloud keys and want a quick npm-based start

Not a fit when

  • You need Yandex search via the current Yandex Cloud Search API: this uses the aging XML protocol
  • You need tests, CI or a single wrapper around all four servers

Example request

Transport

Authentication
API key

Environment variables

YANDEX_FOLDER_ID required
Yandex Cloud folder ID.
YANDEXGPT_API_KEY required, secret
API key for the YandexGPT, Vision and SpeechKit servers.
YANDEX_SEARCH_API_KEY secret
A separate Yandex Search XML API key, only for the search server.

Limitations

The package is not published to npm; install by cloning. yandex-search-server uses a separate, aging Yandex Search XML API with a YANDEX_SEARCH_API_KEY that's harder to obtain than the modern Yandex Cloud Search API. Each server runs as its own process; there is no unified entry point. No tests or CI.

How to disable. Remove the relevant entry from your mcporter or MCP client config and stop the node process.

FAQ

Do all four servers use one key?

No, YandexGPT, Vision and SpeechKit use YANDEX_FOLDER_ID and YANDEXGPT_API_KEY, while search uses a separate YANDEX_SEARCH_API_KEY from yandex.com/dev/xml.

Which voices are available for TTS?

alena, filipp, jane, omazh, zahar, ermil, marina.

README in short

The Russian README describes each of the four servers in its own section with tools, a launch command and an mcporter call example, gives a general mcporter config add setup table for each server, and a section on obtaining Yandex Cloud and Yandex Search XML keys.
