What is the Tts MCP MCP server?

OpenAI Text to Speech APIを活用したコマンドラインツールとMCPサーバー. The tts mcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 1 defined tool rather than through you.

What it actually does

A Model Context Protocol (MCP) server and command-line tool for high-quality text-to-speech generation using the OpenAI TTS API.

Adding it to your client

tts-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Its toolset

Everything the assistant can do here goes through one of these:

  • text-to-speech — Tool for converting text to speech and playing it

Configuration

You will need one environment variable: OPENAI_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Caveats

  • 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.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the tts mcp mcp server does with a few real requests.

When to reach for it

This sits in the AI and media services group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Tts MCP's toolset — text-to-speech — is a fair guide to whether it matches your workflow. It is maintained by nakamurau1; 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We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Frequently asked questions

It connects Tts MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 1 tool (text-to-speech) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Tts MCP directly.
