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 | $0.00060 | $0.00665 |
| Opus 5 | $0.00030 | $0.00332 |
| Sonnet 5 | $0.00012 | $0.00133 |
| Haiku 4.5 | $0.00006 | $0.00067 |
Grade A, and why
ledfx-mcp-tooling 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 10d 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 — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LedFX MCP Tooling
Workflow
- Query effect schemas before setting effects.
- Build config using only supported properties from the selected schema.
- Validate colors and gradients before calling tool writes.
- Apply effect fallbacks when preferred effects are unavailable.
- Write scenes after effect application checks pass.
- Build playlists from scene IDs and patch per-scene durations only when needed.

Blender Mask Rules
- Mask MUST be audio-reactive.
Non-Reactiveeffects (gradient, fade, singleColor, rainbow, random_flash) as masks produce static, lifeless blenders. - Best 1D masks:
energy,scroll,scroll_plus,wavelength,equalizer,bar,spectrum,filter,hierarchy,vumeter - Best beat-locked masks:
bar,strobe,real_strobe - Avoid dual strobe: don't put strobe in both foreground AND mask
- Use
ledfx_list_effect_typeswithfilter_role: "mask"to get valid mask candidates.
Guardrails
- Prefer
ledfx_set_blenderover direct blender config writes. - Keep gradients in
linear-gradient(... <pct>%, ...)format. - Reject invalid palette references early.
- Keep tool errors explicit and actionable.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ledfx-mcp-tooling is a skill published in the GitHub repository abossard/ledfx-mcp (4 stars, last pushed 2mo ago), licensed MIT. It adds 60 tokens to every session and 665 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
