InkQuest MCP server

InkQuest

Interactive language-learning fiction built with Next.js, Supabase, and OpenNext Cloudflare.

Getting Started

Install dependencies and run the development server:

pnpm install
pnpm dev

Open http://localhost:3000.

Generated Stories Foundation

The first cloud-generation foundation includes:

• Supabase credit ledger, reservations, story graph, jobs, outbox, billing tables, and RLS in supabase/migrations/202608220001generatedstory_billing.sql.
• Server-created Lemon Squeezy checkouts and idempotent webhook processing.
• Authenticated quote and generated-story job creation APIs.
• Cloud adapter contracts and a reusable scene enrichment core in tools/story-pipeline/src/core.

Required server environment variables:

NEXT_PUBLIC_SUPABASE_URL
NEXT_PUBLIC_SUPABASE_ANON_KEY
NEXT_PUBLIC_GOOGLE_CLIENT_ID
SUPABASE_SERVICE_ROLE_KEY
NEXT_PUBLIC_SITE_URL

LEMONSQUEEZY_API_KEY
LEMONSQUEEZY_STORE_ID
LEMONSQUEEZY_WEBHOOK_SECRET
LEMONSQUEEZY_SUBSCRIPTION_VARIANT_ID
LEMONSQUEEZY_SUBSCRIPTION_CREDIT_GRANT
LEMONSQUEEZY_CREDIT_PACK_VARIANT_ID
LEMONSQUEEZY_CREDIT_PACK_GRANT

GENERATION_PRICING_VERSION
GENERATION_OPENING_TEXT_CREDITS
GENERATION_OPENING_TTS_CREDITS
GENERATION_SCENE_TEXT_CREDITS
GENERATION_SCENE_TTS_CREDITS

NEXTPUBLICGOOGLECLIENTID is the Web OAuth client ID from Google Cloud. Add each deployed site origin (including local development) to its authorized JavaScript origins, and enable Google provider in Supabase.

Credit-pack variables are optional until that product is enabled. Generation pricing falls back to 20 credits for opening text, 10 for opening TTS, 12 for scene text, and 6 for scene TTS when the corresponding environment variables are missing or invalid. TTS pricing is required only when everyscene is offered. Never expose the service-role key, Lemon API key, or webhook secret through a NEXTPUBLIC_ variable.

Apply the migrations in filename order. Existing environments that already ran the first two migrations should next apply supabase/migrations/202608230001generatedstory_tts.sql; it creates the private audio bucket and adds independent TTS commit/retry/refund transactions.

The generation execution path is:

Next.js → inkquest-generation Queue → generation-dispatcher → Cloud Run story-pipeline Worker

Additional main-app variables:

GENERATION_DISPATCH_SECRET
GENERATED_AUDIO_BUCKET

Cloud Run Worker variables:

SUPABASE_URL
SUPABASE_SERVICE_ROLE_KEY
GENERATION_WORKER_TOKEN
LLM_CHAT_COMPLETIONS_URL
LLM_API_KEY
LLM_MODEL
LLM_PROMPT_VERSION
TENCENT_SECRET_ID
TENCENT_SECRET_KEY
TENCENT_REGION
TENCENT_TTS_VOICE
AZURE_SPEECH_KEY
AZURE_SPEECH_REGION
AZURE_TTS_VOICE_ZH
AZURE_TTS_VOICE_EN
STORY_TTS_ZH_PROVIDER
STORY_TTS_EN_PROVIDER
GENERATED_AUDIO_BUCKET

GENERATEDAUDIOBUCKET defaults to generated-audio. Configure the Azure Speech key and region on the Cloud Run Worker; the verified evaluation resource uses eastasia. Azure is preferred for both Chinese and English when configured, with zh-CN-Xiaoxiao:DragonHDFlashLatestNeural and en-US-JennyNeural as defaults. Set STORYTTSZHPROVIDER or STORYTTSENPROVIDER to azure or tencent to override selection. The Worker image also installs FFmpeg to normalize multi-part Tencent audio into one seekable MP3 before upload.

Create inkquest-generation and inkquest-generation-dlq in Cloudflare, deploy the main app, then deploy tools/generation-dispatcher/wrangler.jsonc. Configure GENERATIONWORKERURL on the dispatcher and store GENERATIONWORKERTOKEN with wrangler secret put.

For local development, start the Worker in a separate terminal before generating a story:

PORT=8080 pnpm --filter @inkquest/story-pipeline worker:start
