Omnicinema

A master asset-creation engine exposed as a local Model Context Protocol (MCP) server. (Package and directory: omnicinema-mcp, on the external drive.)

One local server that plans, generates, and assembles production assets end-to-end:

• 🧠 Multi-agent persona consultation — a Director of Photography, Graphic Designer, Voice Director, and Music Producer "debate" and compile a rigid prompt strategy before anything is generated.
• 🖼️ Image & design engine — cinematic photos, transparent logos, vector art, textures, UI mockups. Real offline SVG design + official image APIs (BYO key).
• 🎙️ Voiceover + full music engine — narration, SFX, and complete multi-section songs across genres (hip-hop, rap, cinematic orchestral, rock, lo-fi, electronic) via MusicGen APIs or deterministic local synthesis (WAV + editable MIDI). Reports exact millisecond durations.
• 🎞️ Video pipeline — screenplay with shot-to-shot frame continuity → stock/generative b-roll → frame-accurate Remotion montage (now with locked audio tracks) → MP4.
• 🛡️ Free-tier budget guard — persistent usage tracking with a user-gate that halts before exhausting a quota.
• 🔌 Inter-tool REST API — a localhost, token-authed endpoint so another local tool can request assets programmatically.
• 🔭 Human-in-the-loop discovery — scans official catalogs and queues suggestions for explicit approval.

✋ Scope & ethics (please read)

Everything here uses official, documented APIs with your own keys, within each service's Terms of Service. It does not, and will not:

• reuse browser session tokens or scrape hosted web sandboxes (e.g. Seedance / Higgsfield / Suno / Udio web UIs) to obtain "free" generations or bypass paid tiers;
• auto-integrate or execute arbitrary endpoints/code discovered online.

If a service has no first-party API you can get a key for, it is out of scope. The always-available fallbacks — offline SVG design and offline MIDI/WAV music synthesis — need no keys and no network.

Requirements

• Node.js ≥ 18.17 (developed on Node 26).
• Optional, for video rendering: the Remotion toolchain (installed on demand) + ffmpeg.
• Optional: ffprobe (part of ffmpeg) for measuring non-WAV audio durations.
• An external volume if you want everything off your system drive (defaults to /Volumes/PortableSSD/omnicinema-mcp).

Install

cd /Volumes/PortableSSD/omnicinema-mcp
npm install          # core server (lightweight)
npm run build        # compile to dist/
npm run setup:render # optional: install the Remotion render toolchain
npm install -g .     # optional: expose the `omnicinema-mcp` bin globally

Onboarding

1. The limits database

The budget guard persists usage to data/usage-limits.json. You don't create it by hand — it's auto-created on first use and rolls daily/weekly/monthly windows forward automatically. Each provider has a conservative default guard rail; override any of them via env:

# LIMIT_<PROVIDER>_<DAILY|WEEKLY|MONTHLY>=<integer>
LIMIT_HUGGINGFACE_DAILY=250
LIMIT_REPLICATE_MONTHLY=1000

Inspect current usage anytime with the check_limits tool. When a generative call would exceed a quota (or nearly exhaust the daily allowance), the tool halts and returns a cost breakdown; re-issue with approveOverBudget: true to proceed.

2. Dependencies

npm install gets the core server. npm run setup:render adds Remotion for video. The install_dependencies tool can detect your OS and install ffmpeg/Blender/Remotion after explicit consent (preview with consent:false, execute with consent:true).

3. Environment keys

cp .env.example .env   # then fill in ONLY the keys you have

Variable	Enables	Get a key
PEXELS_API_KEY / PIXABAY_API_KEY / UNSPLASH_ACCESS_KEY	Stock video/photos/stills	pexels.com/api · pixabay.com/api/docs · unsplash.com/developers
FREESOUND_API_KEY	Stock SFX / ambience	freesound.org/apiv2/apply
HUGGINGFACE_API_TOKEN + HF_IMAGE_MODEL / HF_TTS_MODEL / HF_MUSIC_MODEL / HF_VIDEO_MODEL	HF Inference image / TTS / music / video	huggingface.co/settings/tokens
REPLICATE_API_TOKEN + REPLICATE_IMAGE_MODEL / REPLICATE_MUSIC_MODEL / REPLICATE_VIDEO_MODEL	Replicate image / music / video	replicate.com
FAL_API_KEY + FAL_VIDEO_MODEL	fal.ai video	fal.ai
ANTHROPIC_API_KEY	Optional screenplay enrichment	console.anthropic.com

Model ids are yours to choose, so the tool tracks new models (FLUX, Kokoro, MusicGen, …) without code changes. With no keys at all, the engines still produce real offline output (SVG designs, synthesized music, placeholder footage).

4. The cross-tool programmatic API

Start the localhost REST server so another local tool can drive this engine:

ipc_start  →  { url: "http://127.0.0.1:8787", token: "…" }

Then, from any local process:

TOKEN=…   # from ipc_start (also stored in data/ipc-token.txt)
curl -s localhost:8787/schema -H "Authorization: Bearer $TOKEN"          # metadata contract
curl -s localhost:8787/limits -H "Authorization: Bearer $TOKEN"          # usage
curl -s localhost:8787/assets/image -H "Authorization: Bearer $TOKEN" \
  -H 'content-type: application/json' \
  -d '{"assetKind":"logo","subject":"Nova Labs","style":"vibrant"}'

Security: bound to 127.0.0.1, bearer-token required (auto-generated to data/ipc-token.txt, mode 0600), no CORS, no code execution. Over-budget requests return HTTP 402 with a breakdown; retry with "approveOverBudget": true.

Tools (15)

Tool	Purpose
consult_personas	Run the persona debate and return the compiled brief (no generation).
generate_image	Cinematic photo / logo / vector art / texture / UI mockup.
generate_voiceover	Spoken narration with precise ms duration.

Personas

Each asset kind has a lead persona (and sometimes advisors). The consultation compiles a positive prompt, a negative prompt, and technical parameters, with a transcript of the debate.

Persona	Leads	Dictates
Director of Photography	cinematic-photo, texture	lens, volumetric lighting, shadows, angle, depth of field
Graphic Designer / Vector Artist	logo, vector-art, ui-mockup	flat color, padding, SVG-clean geometry, palette
Voice Director & Audio Engineer	voiceover, sfx (advises soundtrack)	pacing/WPM, inflection, ducking, frequency treatment
Music Producer & Beats Engineer	soundtrack	BPM, key, verse/chorus structure, instrumentation

Audio & music engine

generate_soundtrack composes a full arrangement (intro/verse/chorus/…): the Music Producer plans BPM, key, structure, and instrumentation per genre, then the engine either calls a MusicGen/AudioCraft API (generative:true + a configured key) or renders it locally to WAV + editable MIDI with deterministic synthesis (bass, chords, drums, arp). Every audio asset returns an exact millisecond duration, so run_cinema_pipeline's narration/soundtrack options lock audio to the video timeline frame-accurately.

Output layout

assets/                      # standalone image/audio assets (<subject>_<kind>.<ext>, plus .mid)
projects/<id>/               # a video project: screenplay, timeline.json, clips, audio, manifest
output/<id>.mp4              # rendered video
data/usage-limits.json       # budget guard database  (gitignored)
data/review-queue.json       # discovery suggestions   (gitignored)
data/ipc-token.txt           # IPC bearer token 0600   (gitignored)

Test / eval

npm run eval   # (alias: npm test) — 29 tests, fully offline (no network, no keys)

Covers persona lead-selection & determinism, budget rollover/gate, music-synthesis duration accuracy + valid WAV/MIDI, offline SVG design, the IPC auth/schema/generate contract, discovery safety gates, and the video pipeline (continuity, timeline tiling, audio lock).
