Tts MCP server

Brainiall TTS MCP Server

Hosted text-to-speech for AI agents via the Model Context Protocol.

54 neural voices, 9 languages — including native Brazilian Portuguese (pfdora, pmalex, pmsanta) — served from a hosted, pay-per-use API. No GPU, no model downloads, no ElevenLabs subscription: bring one API key and pay $0.008 per 1,000 characters** ($10 free credits on signup).

Why this server

Every other TTS MCP server either runs models locally (heavy, slow to set up) or wraps a third-party key you already pay a subscription for. This one is a hosted, metered API:

• Zero setup — remote server, nothing to install
• Pay per use — $0.008/1K characters, billed against your Brainiall balance
• $10 free credits — sign up at app.brainiall.com
• WAV out — 16-bit PCM, 24 kHz mono, returned as playable MCP audio content or base64 JSON

Quick start

Get an API key at app.brainiall.com ($10 welcome credits, no card required).

VS Code / GitHub Copilot

The button installs the remote server in discovery mode, so VS Code can list its tools without a secret. Synthesis still fails closed until you add your Brainiall API key. For a secure workspace configuration that prompts once and stores the key in VS Code's secret storage, copy .vscode/mcp.json into your project or clone this repository, then start brainiallTts from MCP: List Servers.

{
  "inputs": [
    {
      "type": "promptString",
      "id": "brainiall-api-key",
      "description": "Brainiall API key",
      "password": true
    }
  ],

      "headers": {
        "Authorization": "Bearer ${input:brainiall-api-key}"
      }
    }
  }
}

After the server starts, try:

Use Brainiall TTS to list the Brazilian Portuguese voices, then read “Olá do VS Code” with pf_dora.

The install URL format and secret-input configuration follow the official VS Code MCP guide and configuration reference.

GitHub Copilot cloud agent

Use the restricted remote-server configuration for Copilot cloud agent or Copilot code review. It allowlists the three Brainiall tools and resolves the Bearer token from the repository's COPILOTMCPBRAINIALLAPIKEY Agents secret; no API key is committed.

Continue (VS Code / JetBrains)

Copy the ready-to-use Continue MCP block to .continue/mcpServers/brainiall-tts.yaml, then put BRAINIALLAPIKEY=your-key in .continue/.env. Keep that .env file out of version control.

The block uses Continue's supported streamable-http transport and resolves the key through ${{ secrets.BRAINIALLAPIKEY }}; no credential is committed. See the Continue setup and smoke test.

Dify builders

For a Dify speech workflow, use the open-source BRAINIALL Speech provider and keep the API key in Dify's credential store. The bounded Dify intent route explains the caller-owned boundary; it is not a Dify partnership or a guarantee of production behavior.
