Set the active quality level by name or index.
AI agents use unity_settings_set_quality_level to create or update resources in Unity MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Unity MCP Server environment.
The tool modifies Unity project quality settings, which affects rendering and performance configurations. This is a Write action (reversible configuration change) rather than Execute because it sets a discrete parameter rather than running arbitrary code.
From the tool's definition Tool name contains 'set' (indicates modification) and description states 'Set the active quality level', which modifies project configuration settings. This is a reversible change to project state.
Documented attack patterns abuse exactly the kind of access unity_settings_set_quality_level gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Unity MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for unity_settings_set_quality_level:
{
"version": "1",
"default": "deny",
"tools": {
"unity_settings_set_quality_level": {
"limits": [
{
"counter": "unity_settings_set_quality_level_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}unity_settings_set_quality_level stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Set the active quality level by name or index. It is categorised as a Write tool in the Unity MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_settings_set_quality_level: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Unity MCP Server. Nothing to install.
unity_settings_set_quality_level is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the unity_settings_set_quality_level rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for unity_settings_set_quality_level. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
unity_settings_set_quality_level is provided by the Unity MCP Server MCP server (anklebreaker-studio/unity-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
