Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00064 | $0.02300 |
| Opus 5.5 | $0.00026 | $0.00920 |
| Sonnet 5.5 | $0.00013 | $0.00460 |
| Haiku 4.5 | $0.00006 | $0.00230 |
Grade A, and why
media scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Media
DCC-agnostic media utilities for render, playblast, flipbook, and review artifacts. FFmpeg and matching FFprobe are external, operator-approved prerequisites, not bundled with Core. Every media tool uses only installed binaries; none installs vx, downloads FFmpeg, or invokes a launcher that might bootstrap dependencies. A missing runtime is an actionable preflight failure.
Use media__check_runtime before expensive render/export work. Prefer native
DCC skills for creating the render output, then use media__probe,
media__sequence_to_mp4, media__thumbnail, media__transcode,
media__transcode_audio, or media__extract_frames to inspect or repackage
files already on disk. Discover the capability, follow the returned load or
describe step, and call the returned tool slug with typed arguments. Do not
guess gateway slugs or replace the tool with arbitrary shell commands.
Safety Contract
This skill intentionally exposes typed media operations, not a generic
vx <command> runner. Every tool builds a fixed argument vector for the
resolved FFmpeg or FFprobe executable without shell=True, validates paths
and enum fields, rejects option-like paths, and requires explicit overwrite
intent before replacing outputs. Verified audio-only output is stricter: its
destination must be fresh and cannot be overwritten.
Runtime selection and preparation
FFmpeg selection follows this priority:
DCC_MCP_MEDIA_FFMPEG_BIN, if set to an absolute executable path.- An already-installed FFmpeg in the local vx store (
VX_HOME, or~/.vxby default), discovered from local files without executing vx. ffmpegon the server process's systemPATHif there is no installed vx runtime.
The vx lookup checks the vx 0.9.37 provider layouts under
<vx-root>/store/ffmpeg/<version>, with at most 128 entries and the highest
numeric stable version first. It does not require a vx launcher, consult
vx.toml or vx.lock, or select preview/custom version names. Pin a version
or use an unsupported layout through explicit executable overrides instead.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

media is a skill published in the GitHub repository dcc-mcp/dcc-mcp-core (70 stars, last pushed today), licensed MIT. It adds 64 tokens to every session and 2,300 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
