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 | $0.01443 |
| Opus 5 | $0.00000 | $0.00722 |
| Sonnet 5 | $0.00000 | $0.00289 |
| Haiku 4.5 | $0.00000 | $0.00144 |
Grade A, and why
memoryprofiler 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 5d 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unity Open MCP — Memory Profiler Extension
Skill for AI agents capturing Unity Memory Profiler snapshots
(com.unity.memoryprofiler) in a Unity project through the unity-open-mcp
MCP server.
This domain is embedded in the bridge, compile-gated on
com.unity.memoryprofiler, and auto-activating. Its tool compiles in only when the project hascom.unity.memoryprofilerinstalled (the bridge sets theUNITY_OPEN_MCP_EXT_MEMORYPROFILERdefine automatically). When the package is present, thememoryprofilergroup activates automatically for the session — the tool appears inListToolswith no manualmanage_toolscall.
Preconditions
- Unity Editor is open with the target project.
unity_open_mcp_pingreturnsconnected: true.- The project has
com.unity.memoryprofilerinstalled. Ifcapabilitiesreports thememoryprofilergroup asavailable: false, install the package (Package Manager → Unity Registry → Memory Profiler) and let the bridge recompile. - The
memoryprofilergroup is auto-activated when the package is present — checkunity_open_mcp_manage_tools(action="list_groups"); the group should showactivationSource: "auto". If you deactivated it manually, re-activate withmanage_tools(action="activate", group="memoryprofiler").
Tool
unity_senses_memory_snapshot_capture — capture a Memory Profiler snapshot to
a .snap file. (Sense-prefixed because it pairs with the existing senses
profiler family rather than the typed-editor surface.)
Vocabulary
A Memory Profiler snapshot (.snap file) is an offline capture of the
entire managed + native heap at a moment in time — far deeper than the live
unity_senses_profiler_memory allocator-bytes read. It can be opened in the
Memory Profiler window (Window > Analysis > Memory Profiler) for root-cause
analysis of leaks, large allocations, and asset footprint.
Version-stability note
The Memory Profiler capture surface moved namespaces across Unity versions:
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.

memoryprofiler is a skill published in the GitHub repository AlexeyPerov/Unity-Open-MCP (12 stars, last pushed 7d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,443 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.
