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.

What it costs to keep this loaded
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 | $0.00000 | $0.02097 |
| Opus 5 | $0.00000 | $0.01048 |
| Sonnet 5 | $0.00000 | $0.00419 |
| Haiku 4.5 | $0.00000 | $0.00210 |
Grade A, and why
animation 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 8d 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity Open MCP — Animation Extension
Skill for AI agents driving Unity AnimationClip and AnimatorController assets in a project through the unity-open-mcp MCP server.
This domain is embedded in the bridge and opt-in. Its tools compile in when the built-in animation module is present (the bridge sets
UNITY_OPEN_MCP_EXT_ANIMATIONautomatically — no extra Unity package is needed). Its tool group is hidden fromListToolsuntil the connected session activates it.
Preconditions
- Unity Editor is open with the target project.
unity_open_mcp_pingreturnsconnected: true.- The
animationtool group is activated — callunity_open_mcp_manage_tools(action="activate", group="animation")before invoking anyanimation_*oranimator_*tool. Fresh sessions start with two default-on groups (coreandgate-and-verify); activate the other groups you need on demand.
Tool prefixes
- AnimationClip tools use
unity_open_mcp_animation_*. - AnimatorController tools use
unity_open_mcp_animator_*.
All four mutators run the full gate path with paths_hint scoped to the asset path (.anim or .controller); the two read tools are gate-free. The two modify tools are DESTRUCTIVE — some modification types (ClearCurves / ClearEvents / RemoveCurve on clips, RemoveParameter / RemoveLayer / RemoveState / RemoveTransition on controllers) are irreversible without undo.
Two separate authoring domains
The pack treats clip authoring and controller (state-machine) authoring as separate workflows:
| Workflow | Tools |
|---|---|
| AnimationClip authoring | animation_create → animation_modify (curves, events, frame rate, wrap mode) → animation_get_data |
| AnimatorController authoring | animator_create → animator_modify (parameters, layers, states, transitions) → animator_get_data |
The two are linked via SetStateMotion on the controller side — that's how a clip becomes the motion of a state.
Always get before you modify
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.

animation is a skill published in the GitHub repository AlexeyPerov/Unity-Open-MCP (12 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,097 tokens. 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.
