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 | $0.00000 | $0.01709 |
| Opus 5 | $0.00000 | $0.00855 |
| Sonnet 5 | $0.00000 | $0.00342 |
| Haiku 4.5 | $0.00000 | $0.00171 |
Grade A, and why
audio 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 7d 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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity Open MCP — Audio Extension
Skill for AI agents driving Unity audio (AudioSource / AudioListener / AudioMixer)
in a project through the unity-open-mcp MCP server.
This domain is embedded in the bridge and opt-in. Its tools use the built-in audio module (
AudioSource/AudioListener/AudioMixer/AudioMixerGroupfromUnityEngine.AudioModule) — no Unity package install is required, and they compile into every bridge build. 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
audiotool group is activated — callunity_open_mcp_manage_tools(action="activate", group="audio")before invoking any audio tool. Fresh sessions start with two default-on groups (coreandgate-and-verify); activate the other groups you need on demand. Because audio is built-in,capabilitiesalways reports theaudiogroup asavailable: true(nodomainDefine).
Tool prefixes
Two prefixes share the audio group:
unity_open_mcp_audio_source_*— AudioSource add + typed modify.unity_open_mcp_audio_mixer_*— AudioMixer exposed-parameter set + get.unity_open_mcp_audio_listener_get— AudioListener read (read-only).
Mutating tools accept the standard paths_hint and run the full gate path;
read-only tools (audio_listener_get, audio_mixer_get_parameter) are
gate-free.
Canonical workflow: an audio source
- Discover —
unity_open_mcp_component_list_all(filterAudioSource) orunity_open_mcp_gameobject_findto locate existing sources. Address any host byinstance_id>path>name. - Add a source —
unity_open_mcp_audio_source_addon a GameObject. Setclip_path(Assets/.../*.wav),volume(0-1, default 1),pitch(default 1),loop(default true),play_on_awake(default true),spatial_blend(0=2D, 1=3D, default 0),spatialize, and 3Dmin_distance/max_distance. Returns the source state. Idempotent — re-using an existing AudioSource reportsadded:false. - Tune it —
unity_open_mcp_audio_source_modifyfor the common fields (clip_path,volume,pitch,loop,play_on_awake,spatial_blend,spatialize,min_distance,max_distance,doppler_level,spread). Each field is optional — omit to leave unchanged. - Route to a mixer group — pass
mixer_group_path(anAssets/.../*.mixasset path) toaudio_source_modifyto bindAudioSource.outputAudioMixerGroupto the mixer's first group. Passclear_mixer_group: trueto unbind.
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.

audio 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 1,709 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.
