Remote server (recommended — nothing to install)
Use the](https://www.brainiall.com/transcreve/integracoes/dify-transcreve-ptbr-pipeline)project-scoped Codex configuration. It readsBRAINIALL_API_KEYfrom the environment, allowlists the three Brainiall tools, and prompts before every call.

{ "mcpServers": { "brainiall-tts": { "type": "http", "url": "https://api.brainiall.com/mcp/tts/mcp", "headers": { "Authorization": "Bearer YOUR_BRAINIALL_API_KEY" } } } }
{ "mcpServers": { "brainiall-tts": { "url": "https://api.brainiall.com/mcp/tts/mcp", "headers": { "Authorization": "Bearer YOUR_BRAINIALL_API_KEY" } } } }
Use the official one-click deeplink and the explicit local-model privacy boundary in theLM Studio setup guide.
Use the remote-server schema and environment-backed Bearer header in theOpenCode v2 setup guide.
Use the zero-dependency[partial OpenAI-shaped TTS adapterwhen a client can configure an OpenAI-style speech route but cannot call Brainiall's native endpoint. The adapter returns WAV only, declares the sample rate observed in the WAV header, never retries a metered request, and documents the exact compatibility limits. It is a local reference adapter, not a claim that the hosted Brainiall API is natively OpenAI-compatible.
Hosted text-to-speech for AI agents via theModel Context Protocol.
54 neural voices, 9 languages— including nativeBrazilian Portuguese(pf_dora,pm_alex,pm_santa) — 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).
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 atapp.brainiall.com
- WAV out— 16-bit PCM, 24 kHz mono, returned as playable MCP audio content or base64 JSON
Get an API key atapp.brainiall.com($10 welcome credits, no card required).
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.jsoninto your project or clone this repository, then startbrainiallTtsfromMCP: List Servers.
{ "inputs": [ { "type": "promptString", "id": "brainiall-api-key", "description": "Brainiall API key", "password": true } ], "servers": { "brainiallTts": { "type": "http", "url": "https://api.brainiall.com/mcp/tts/mcp", "headers": { "Authorization": "Bearer ${input:brainiall-api-key}" } } } }
Use Brainiall TTS to list the Brazilian Portuguese voices, then read “Olá do VS Code” withpf_dora.
The install URL format and secret-input configuration follow theofficial VS Code MCP guideandconfiguration reference.
Copy the ready-to-useContinue MCP blockto.continue/mcpServers/brainiall-tts.yaml, then putBRAINIALL_API_KEY=your-keyin.continue/.env. Keep that.envfile out of version control.
The block uses Continue's supportedstreamable-httptransport and resolves the key through${{ secrets.BRAINIALL_API_KEY }}; no credential is committed. See theContinue setup and smoke test.
For a Dify speech workflow, use the open-sourceBRAINIALL Speech providerand keep the API key in Dify's credential store. Thebounded Dify intent routeexplains the caller-owned boundary; it is not a Dify partnership or a guarantee of production behavior.

Run locally (stdio-free, still calls the hosted API)
The server itself is a thin wrapper — you can self-host it and it will proxy toapi.brainiall.comwith your key:
docker build -t brainiall-tts-mcp . docker run -p 8080:8080 -e APIM_KEY=YOUR_BRAINIALL_API_KEY brainiall-tts-mcp # MCP endpoint: http://localhost:8080/mcp

The agent callssynthesize_speech(text=..., language="pt", voice="pf_dora")and receives playable WAV audio.
For copy-ready prompts and smoke tests for narration, accessibility, language practice, and agent alerts, seeAgent workflow recipes.
For REST client testing and automation, import thePostman collection. It contains health, voice-list and two-character synthesis smoke tests and keeps the API key in a collection variable rather than the request URL.
For code generation, API clients, and directory discovery, use the machine-readableOpenAPI 3.1 specification. The specification documents the authenticated voice catalog and WAV synthesis endpoints without embedding an API key.
Pass your Brainiall API key as a Bearer token (see configs above). Usage is metered per character against your account balance — the same key works across all Brainiall APIs (STT, OCR, NLP, image and more atbrainiall.com).
