WHAT IT DOES

What unity_settings_set_physics does on Unity MCP Server

AI agents use unity_settings_set_physics 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.

RISK

Why unity_settings_set_physics is rated Medium

This tool modifies physics engine configuration parameters (gravity, solver iterations, sleep threshold) which are reversible project settings. It does not execute arbitrary code, delete data, or move money. While misconfiguration could affect game behavior and cause project issues, the changes are reversible through reconfiguration.

From the tool's definition Tool name 'unity_settings_set_physics' with description 'Modify physics settings like gravity, solver iterations, sleep threshold, etc.' indicates creation or modification of project configuration data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs unity_settings_set_physics safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Unity MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unity_settings_set_physics, this is the rule to start with:

unity_settings_set_physics Rate-limited

unity_settings_set_physics 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Unity MCP Server, apply this rule, and every unity_settings_set_physics call is checked against it from then on.

FAQ

Questions about unity_settings_set_physics

What does the unity_settings_set_physics tool do? +

Modify physics settings like gravity, solver iterations, sleep threshold, etc. 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.

How do I enforce a policy on unity_settings_set_physics? +

Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_settings_set_physics: 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.

What risk level is unity_settings_set_physics? +

unity_settings_set_physics is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit unity_settings_set_physics? +

Yes. Add a rate_limit block to the unity_settings_set_physics 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.

How do I block unity_settings_set_physics completely? +

Set action: deny in the PolicyLayer policy for unity_settings_set_physics. 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.

What MCP server provides unity_settings_set_physics? +

unity_settings_set_physics 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.
