BytePlus Seed Audio

Generate natural speech and audio with BytePlus Seed Audio 1.0 — from Claude, the terminal, or your own code. Three surfaces over one zero-dependency SDK:

I want to…

Use

Talk to Claude / Claude Code

MCP server (seed-mcp)

Generate from the terminal

CLI (seed)

Claude Code skill

Skill (skills/seed.md)

Build my own integration

SDK (seed-sdk)

Provider: Seed Audio runs on fal.ai (bytedance/seed-audio-1.0) today. The SDK hides this behind a provider abstraction, so when BytePlus releases its native Seed Audio API you flip SEED_PROVIDER=byteplus (and add BYTEPLUS_SEED_API_KEY) — nothing else changes. See seed/providers/.

Prerequisites

Related MCP server: ElevenLabs MCP Server

Install (workspace, for development)

uv sync --all-packages --dev      # installs seed-sdk, seed-mcp, seed-cli

🖥 MCP Server

Expose Seed Audio to Claude Desktop / Claude Code.

pip install seed-mcp                # or: uv pip install ./packages/seed-mcp
export FAL_KEY=<your-fal-key>
python -m seed_mcp                  # stdio transport (default)

Register it (or use the CLI installer, below). Claude config:

{
  "mcpServers": {
    "seed": { "command": "python", "args": ["-m", "seed_mcp"] }
  }
}

Tools

Tool

Purpose

seed_audio_generate

Submit an audio job → returns request_id

seed_check_task

Poll until completed; returns audio_url

seed_list_voices

List preset voice ids

seed_list_models

List Seed models + capabilities

seed_ping

Liveness, provider, credential check

Hosted / Docker

docker build -t byteplus-seed-mcp .
docker run -e FAL_KEY=<key> -e MCP_TRANSPORT=sse -p 8000:8000 byteplus-seed-mcp
# health: GET http://localhost:8000/health

💻 CLI

pip install seed-cli                 # or: pip install 'seed-cli[mcp]'
seed auth login                      # stores FAL_KEY in ~/.seed/credentials

# Generate
seed generate \
  --prompt "A short suspense radio drama in a late-night convenience store." \
  --watch

# With a preset voice
seed voices                          # list presets
seed generate -p "Welcome back to the late show." -v sophie_en_zh --watch

# Voice cloning from reference audio
seed generate -p "In @Audio1's voice: 'Once upon a time…'" \
  --audio-ref https://cdn.example.com/narrator.mp3 --watch

# Track a job
seed status <request_id>
seed watch  <request_id>

# Skill management (Claude Desktop + Claude Code)
seed skill install
seed skill check

Run seed --help for the full command reference.

🧠 Claude Code Skill

skills/seed.md (+ skills/references/) teaches Claude Code how to use Seed Audio well — prompting, voice presets, cloning, multi-speaker scenes, and safety.

seed skill install                   # copies the skill + registers the MCP server
# restart Claude Code, then just ask it to "generate a 20s upbeat intro voiceover"

📦 SDK

from seed import SeedClient

client = SeedClient()                                  # provider from SEED_PROVIDER (default: fal)
task = client.submit_audio(
    "A short suspense radio drama in a late-night convenience store.",
    output_format="mp3",
)
# poll until done
import time
while not (result := client.check_task(task.request_id)).terminal:
    time.sleep(5)
print(result.audio_url)

seed-sdk has zero runtime dependencies (stdlib urllib only).

Credentials

Resolution order (first non-empty wins): explicit arg → FAL_KEY env → ~/.seed/credentials [default] → .env.

Release

Independent per-package PyPI publishes via tags:

git tag sdk/v0.1.0 && git push --tags   # → seed-sdk
git tag mcp/v0.1.0 && git push --tags   # → seed-mcp
git tag cli/v0.1.0 && git push --tags   # → seed-cli

Roadmap

  • Native BytePlus Seed Audio provider (SEED_PROVIDER=byteplus)

  • Local-file upload helper (host local audio/images → public URL)

  • Additional Seed models as they ship
