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 | $0.00504 | $0.00504 |
| Opus 5.5 | $0.00202 | $0.00202 |
| Sonnet 5.5 | $0.00101 | $0.00101 |
| Haiku 4.5 | $0.00050 | $0.00050 |
Grade A, and why
unity-prefab-parser-mcp AGENTS.md 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 1mo 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.
What it actually says
Unity Prefab Parser MCP — Agent Instructions
This MCP server parses Unity text-serialized assets (.prefab, .unity, .asset) into clean, Inspector-visible YAML.
Recommended Workflow
First time on a Unity project:
init_unity_project— scan .meta files, build GUID cache (run once)browse_unity_project— navigate folder tree to find assetslist_unity_assets— list assets in target folder (supports search/filter)parse_unity_file— parse withpreset: "compact"for token efficiency
Subsequent calls: skip init if .unity-mcp-cache.json exists and is < 24h old.
Tool Reference
init_unity_project
- Input:
projectPath(string, required),force(boolean, optional) - Run once per project. Saves cache to
<projectPath>/.unity-mcp-cache.json
browse_unity_project
- Input:
projectPath(string),subPath(string, optional),depth(number, default 2) - Returns folder tree with asset counts
list_unity_assets
- Input:
directory(string),type("prefab"|"unity"|"asset"|"all"),recursive(boolean),search(string),limit(number) - Returns grouped asset list with absolute paths
parse_unity_file
- Input:
filePath(string),config(object withpreset: "compact"|"standard"|"minimal") - Returns clean YAML with component data
parse_unity_prefab (deprecated)
- Alias for parse_unity_file
Preset Guide
compact— 92% token reduction, best for analysisstandard— balanced, shows asset type commentsminimal— structural overview only

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.

unity-prefab-parser-mcp AGENTS.md is an instructions file published in the GitHub repository luckynee/unity-prefab-parser-mcp (3 stars, last pushed 5mo ago), licensed MIT. It adds 504 tokens to every session, about $0.0020 per session on Opus 5.5. 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.
