What it does

Object Get Data is an agent skill from IvanMurzak/Unity-MCP. Get serialized data for a Unity UnityEngine.Object — all serializable fields and properties. Supports token-saving path-scoped reads via paths or viewQuery. Pair with 'object-modify' when you need to write back.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Game Development, covering Game development. It works with Model Context Protocol. The repository describes itself as: AI Skills, MCP Tools, and CLI for Unity Engine. Full AI develop and test loop. Use cli for quick setup. Efficient token usage, advanced tools. Any C method may be turned into a… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Game development

Example prompts

  • “object-modify”
  • “/object-get-data”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 4c8056f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm and npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Object Get Data loads about 1.8k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 245 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

object-get-data
description
Get serialized data for a Unity `UnityEngine.Object` — all serializable fields and properties. Supports token-saving path-scoped reads via `paths` or `viewQuery`. Pair with 'object-modify' when you need to write back.

Object / Get Data

Get data of the specified Unity Object. Returns serialized data of the object including its properties and fields. If need to modify the data use 'object-modify' tool.

Path-scoped reads (token-saving)

Supply paths (a list of paths) to read only the listed fields/elements via Reflector.TryReadAt, or viewQuery (a ViewQuery) to navigate to a subtree and/or filter by name regex / max depth / type via Reflector.View. These two parameters are mutually exclusive — supply at most one. When neither is supplied the full object is serialized (backwards compatible).

Path syntax

fieldName, nested/field, arrayField/[i], dictField/[key]. Leading #/ is stripped.

How to Call

bash
unity-mcp-cli run-tool object-get-data --input '{
  "objectRef": "string_value",
  "paths": "string_value",
  "viewQuery": "string_value"
}'

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

bash
unity-mcp-cli run-tool object-get-data --input-file args.json

Or pipe via stdin (recommended):

bash
unity-mcp-cli run-tool object-get-data --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

NameTypeRequiredDescription
objectRefanyYesReference to UnityEngine.Object instance. It could be GameObject, Component, Asset, etc. Anything extended from UnityEngine.Object.
pathsanyNoOptional. List of paths to read individually via Reflector.TryReadAt. Each path may target a different depth. Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Mutually exclusive with 'viewQuery'.
viewQueryanyNoOptional. View-query filter routed through Reflector.View — combines a starting Path, a case-insensitive NamePattern regex, MaxDepth, and an optional TypeFilter. Mutually exclusive with 'paths'.
