Docker Flickies MCP Server

flickies

Video toolkit. One port. Zero cloud. Lipsync, face restore, ffmpeg. Fire-and-forget async jobs. Webhooks. Spec-first OpenAPI; typed Go + Python clients generated from the same spec.

The video sibling of audiolla (audio) and talkies (speech). Same wire format, same async-job model, same bind-mount-/data story, same Makefile shape, same :latest + :latest-cuda split, same opt-in non-commercial gate.

POST a JSON body. Get a video back. Drive it from curl, shell scripts, the generated Go/Python clients, or point an LLM agent at the MCP endpoint.

No account. No subscription. docker run and you're done.

What's in the box

Quick start

docker run -d --name flickies \
  -v $HOME/flickies-data:/data \
  -p 8000:8000 \
  psyb0t/flickies:latest

curl -s -X POST http://localhost:8000/v1/video/info \
  -H "Content-Type: application/json" \
  -d '{"file_path": "uploads/clip.mp4"}' | jq

CUDA image at psyb0t/flickies:latest-cuda runs every engine at usable speed. CPU image runs all ffmpeg ops (trim/concat/transcode incl. gif/scale/mux/extract/thumbnail-grid/info) + Wav2Lip-CPU (~44s for a 3s clip; OK for short ones). GFPGAN + LatentSync 1.5 are CUDA-only — CPU image refuses to load them.

Weights live in the standard HuggingFace cache layout under /data/hf/hub/models--<org>--<name>/{blobs,snapshots,refs}/… — content-addressed blobs, snapshot-named symlinks, reusable by any other HF-aware tool sharing the bind mount (not just flickies). Sources:

Lazy by default — each engine fetches its repo on first request. Set FLICKIES_ENABLED_ENGINES=wav2lip,gfpgan (or FLICKIES_PREFETCH_ALL=1) to pull at boot before uvicorn starts. FLICKIES_OFFLINE=1 disables auto-download (operators stage the snapshot dir manually).

Auth

Bearer token set via env. Any string works:

docker run -e FLICKIES_AUTH_TOKEN=testme ...
# clients then send: curl -H "Authorization: Bearer testme" ...

Unset → auth disabled. /healthz is always probe-exempt.

Logging

Structured JSON to both stderr AND a rotating file at FLICKIES_LOG_FILE (default /data/logs/flickies.log, 50 MB × 5 backups). Every line carries time (ISO 8601 UTC sub-ms), level, logger, file, line, func, msg, trace_id, request_id + typed extras.

Inbound X-Request-Id (UUID v4 OR ULID; garbage → server mints fresh) threads onto the logging scope via ContextVar + echoes back on the response. Outbound httpx fetches forward X-Request-Id + X-Trace-Id so the next hop's logs correlate. Sensitive keys (authorization, cookie, *token*, *secret*, hf_*, sk-ant-*) get [REDACTED] automatically at format time.

Default level is INFO; set FLICKIES_LOG_LEVEL=DEBUG for reconstruction-grade tracing: every ffmpeg/ffprobe command + result, each transform's decision (e.g. trim stream_copy vs precise_reencode) + output size, engine inference timing (wall_secs), URL fetch/upload byte counts, and job lifecycle. Logged URLs are stripped of their query string so presigned credentials never reach the logs.

MCP

Eleven tools at /v1/mcp via streamable-HTTP JSON-RPC: list_engines, info, lipsync, restore, transcode, trim, concat, scale, mux_audio, extract_audio, thumbnail_grid. Point a function-calling LLM at it (LibreChat, Cursor, Claude desktop with the MCP connector) and it drives the pipeline.

Hardware ceiling

Tested target: RTX 3060 12 GB. Fits LatentSync 1.5 (~8 GB) with headroom. Wav2Lip + GFPGAN chain peaks at ~5 GB. One engine resident at a time — different model request triggers hot-swap eviction.

License posture

Wav2Lip variants are trained on LRS2 (non-commercial). The server refuses to load them unless FLICKIES_ENABLE_NONCOMMERCIAL=1 is set in the server env. LatentSync 1.5 (Apache-2.0) is the commercial-safe default — no gate.

Same pattern as audiolla's MusicGen / matchering gates.

Spec-first

Every request/response shape lives in openapi.yaml. The Pydantic models in src/flickies/schema/_generated.py, the Go client in pkg/clients/go/client.gen.go, and the Python client in pkg/clients/python/flickies-client/ are all generated from that single file.

make generate              # regenerate all three (server models + Go client + Python client)
make generate-models       # just server-side Pydantic
make generate-client-go    # just the Go client
make generate-client-python # just the Python client
make generate-check        # CI gate — fail if generated files drift from openapi.yaml

Never hand-edit generated files. Edit openapi.yaml, run make generate, commit everything together.

Generated clients

Go

go get github.com/psyb0t/docker-flickies/pkg/clients/go@latest

import flickies "github.com/psyb0t/docker-flickies/pkg/clients/go"

c, _ := flickies.NewClient("http://localhost:8000")
resp, err := c.PostVideoLipsync(ctx, flickies.VideoLipsyncRequest{...})

Python

pip install "git+https://github.com/psyb0t/docker-flickies.git#subdirectory=pkg/clients/python/flickies-client"

from flickies_client import Client
from flickies_client.api.lipsync import post_video_lipsync
from flickies_client.models import VideoLipsyncRequest

client = Client(base_url="http://localhost:8000")
result = post_video_lipsync.sync(client=client, body=VideoLipsyncRequest(...))

Agent integrations

The skill works in any agent that reads .agents/skills/ (such as peen), and installs natively in the clients below.

Claude Code

claude plugin marketplace add psyb0t/agents
claude plugin install flickies@psyb0t

Claude Code prompts for the flickies URL and, if auth is enabled, the token — the token is stored in your OS keychain.

Codex

codex plugin marketplace add psyb0t/agents
codex plugin add flickies@psyb0t

Installed via the marketplace, the skill invokes as $flickies:flickies. Codex also picks the skill up automatically with no install in any repo containing .agents/skills/, where it invokes as plain $flickies.

OpenClaw

The skill is published to ClawHub on every release:

openclaw skills install @psyb0t/flickies

For MCP clients that speak local stdio, the @psyb0t/flickies plugin bridges to flickies' /v1/mcp endpoint:

openclaw plugins install clawhub:@psyb0t/flickies

Then set FLICKIES_URL (and FLICKIES_AUTH_TOKEN if the server requires one).

aigate integration

Mounts in aigate at /flickies/ and /flickies-cuda/ behind the same nginx → make run-bg lives. FLICKIES=1 and FLICKIES_CUDA=1 toggle the variants.
