package-search

package-search is a skill for Claude Code, Codex from IvanMurzak/Unity-MCP. It costs 48 tokens per session (1,115 once invoked), scanned A, original, Apache-2.0.

A Unity Package Manager search tool for finding packages in Unity's registry and among packages already installed locally. Unity packages add reusable libraries or features to a Unity project.

In plain words
What is it for?
Use it to search by package name, display name, or description keyword, then view versions, installation status, and compatible versions. You provide a search query and can limit the number of results.
Why use it?
It helps you find the right package and see whether it is already installed, without checking the online registry and local project files separately. It can search offline or fetch exact matches from the live registry.

About the project

Unity-MCP connects AI coding agents to the Unity game engine through MCP, letting them work with the Unity Editor and running games. It is used by game developers to generate code, automate development and testing, debug projects, and add AI-driven behavior to games. The catalogue entries provide skills, instructions, an MCP integration, and settings for operating this workflow.

Token cost

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.

Security

Grade A, and why

package-search 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 6d 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 — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Search for packages in both Unity Package Manager registry and installed packages. Use this to find packages by name before installing them. Returns available versions and installation status. Searches both the Unity registry and locally installed packages (including Git, local, and embedded sources). Results are prioritized: exact name match, exact display name match, name substring, display name substring, description substring. Note: Online mode fetches exact matches from live registry, then supplements with cached substring matches.

Inputs

  • query — package id, name, display name, or description keyword (case-insensitive). Required.
  • maxResults (default 10) — caps the returned list.
  • offlineMode (default true) — when false, hits the live registry for exact matches; cached registry data still backs the substring matches in both modes.

Result composition

Each entry includes name, display name, latest version, truncated description, install status, installed version (if any), and the top-5 compatible versions.

How to Call

unity-mcp-cli run-tool package-search --input '{
  "query": "string_value",
  "maxResults": 0,
  "offlineMode": false
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool package-search --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool package-search --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

Input

Name Type Required Description
query string Yes The package id, name, or description. Can be: Full package id 'com.unity.textmeshpro', Full package name 'TextMesh Pro', Partial name 'TextMesh' (will search in Unity registry and installed packages), Description keyword 'rendering' (searches in package descriptions).
maxResults integer No Maximum number of results to return. Default: 10
offlineMode boolean No Whether to perform the search in offline mode (uses cached registry data only). Default: true. Set to false to fetch latest exact matches from Unity registry.

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.
