Get the terrain steepness (slope angle in degrees) and surface normal at a world position.
AI agents call unity_terrain_get_steepness to retrieve information from Unity MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries terrain properties (slope angle and surface normal) at a specified location. It performs a read-only operation that retrieves information about the game world state without modifying, creating, deleting, or executing any external operations. The returned data is purely informational for scene analysis or gameplay mechanics, with minimal security risk if misused by an agent.
From the tool's definition Tool name contains 'get' and description states 'Get the terrain steepness...at a world position', indicating data retrieval with no side effects.

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_terrain_get_steepness:
{
"version": "1",
"default": "deny",
"tools": {
"unity_terrain_get_steepness": {}
}
}unity_terrain_get_steepness is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the terrain steepness (slope angle in degrees) and surface normal at a world position. It is categorised as a Read tool in the Unity MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_terrain_get_steepness: 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_terrain_get_steepness is a Read tool with low risk. Read-only tools are generally safe to allow by default.
