upilot-unity-mcp

A set of instructions for using the UPilot MCP server to inspect and change Unity projects, where Unity is a game-development editor.

In plain words
What is it for?
Working with Unity scenes and assets, checking console and compile errors, running tests and builds, taking screenshots, and monitoring longer tasks.
Why use it?
It helps diagnose project errors and automate editor tasks through a coding agent instead of handling every check manually.

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.

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

upilot-unity-mcp 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 yesterday.

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

UPilot Unity MCP

This is the repository-scoped entry point for Codex auto-discovery.

In a UPilot context, 追踪器 means UPilot Tracer (UPilot 追踪器); MonoHook is only the internal implementation technology or a preserved compatibility identifier.

Read the canonical skill at ../../../skills/upilot-unity-mcp/SKILL.md and follow it. For installation tasks, read ../../../skills/upilot-unity-mcp/references/installation.md before changing a Unity project.

Changes

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.
