Modify player settings like company name, product name, bundle version, run in background.
AI agents use unity_settings_set_player 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.
This tool modifies game project settings (company name, product name, version info, runtime behavior) but does not delete, execute arbitrary code, move money, or trigger external operations. These are reversible configuration writes. While such modifications could affect build output and deployment, they are standard project configuration changes typical of Write category tools.
From the tool's definition Tool description states it can 'Modify player settings like company name, product name, bundle version, run in background', which are configuration changes that create or alter data in the project.
Documented attack patterns abuse exactly the kind of access unity_settings_set_player 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_player:
{
"version": "1",
"default": "deny",
"tools": {
"unity_settings_set_player": {
"limits": [
{
"counter": "unity_settings_set_player_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}unity_settings_set_player 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.

Modify player settings like company name, product name, bundle version, run in background. 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_player: 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_player 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_player 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_player. 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_player 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.
