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 | $0.00061 | $0.01747 |
| Opus 5 | $0.00030 | $0.00873 |
| Sonnet 5 | $0.00012 | $0.00349 |
| Haiku 4.5 | $0.00006 | $0.00175 |
Grade A, and why
ae-setup 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 yesterday.
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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Getting After Effects connected
The tools talk to a small panel that runs inside After Effects. Three things must be true for that to work: the panel is installed, Adobe is willing to load it, and AE is open.
Assume the person you are helping is a motion designer, not a developer. They should never need to open a terminal — you have tools for all of this.
Always start with check_setup
check_setup is read-only and safe to call at any time. It returns a checks array and a nextSteps list already written in plain language.
Relay nextSteps to the user directly. Do not paraphrase it into jargon, and do not invent steps it did not mention.
A timeout is not a disconnection
Before you start any repair, work out which of three failures you have. They read alike and their remedies contradict each other:
- Did not answer in time — something is listening; it is just too busy to reply. After Effects is single-threaded, so a long script or a modal dialog waiting for a click blocks it completely. Nothing is broken and nothing needs installing. The call did reach After Effects and may still be running, so do not re-send it.
- Cannot reach — nothing is listening. That is the case the repair path below is for.
- Waited behind another op for the write queue and was dropped — the panel
is fine and this call never left the server, so nothing in the project was
changed. Writes are serialized so that they land in the order the agent issued
them and nothing drops into the middle of work the user asked for as one
thing; something in front is taking a very long time, usually a long
run_batch. Re-sending is safe here, once the work in front has finished; this is the one of the three where it is. Find out what is in front withget_joborawait_job— reads are never queued, solist_andget_calls still answer.
The message itself tells you which one you have; the queue error says in as many words that nothing was written. Never collapse them into "the bridge is playing up", because "re-send it" and "do not re-send it" are the two answers.
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.

ae-setup is a skill published in the GitHub repository Engine-Room-Games/after-effects-mcp (6 stars, last pushed 3d ago), licensed MIT. It adds 61 tokens to every session and 1,747 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.
