What is the MS MCP server?

If you already use MS, the ms mcp server is the piece that lets your assistant work with it directly. Provides text-to-speech and speech-to-text capabilities using Windows' built-in speech services.

What the server does

A Model Context Protocol (MCP) server that provides text-to-speech and speech-to-text capabilities using Windows' built-in speech services. This server leverages the native Windows Speech API (SAPI) through PowerShell commands, eliminating the need for external APIs or services.

  • Text-to-Speech (TTS) using Windows SAPI voices
  • Speech-to-Text (STT) using Windows Speech Recognition
  • Simple web interface for testing
  • No external API dependencies
  • Uses native Windows capabilities

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • text_to_speech — Parameters: - text (required): The text to convert to speech - voice (optional): The voice to use (e.g., "Microsoft David Desktop") - speed
  • speech_to_text — Records audio and converts it to text using Windows Speech Recognition

Installation

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Credentials and setup notes

  • Windows 10/11 with Speech Recognition enabled - Node.js 16+ - PowerShell

Where it fits

Plenty of AI and media services servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MS's toolset — text_to_speech, speech_to_text — is a fair guide to whether it matches your workflow. It is maintained by ExpressionsBot; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
