AI agents invoke landscape to trigger processes or run actions in Ue. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
landscape can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access landscape gives an agent. Each links to the full case and the policy that stops it:

Landscape terrain: info, layers, sculpting, painting, materials, heightmap import. Actions: - get_info: Get landscape setup - list_layers: List paint layers - sample: Sample height/layers. Params: x, y - list_splines: Read landscape splines - get_component: Inspect component. Params: componentIndex - set_material: Set landscape material. Params: materialPath - add_layer_info: Register paint layer (creates LayerInfo asset + binds to active landscape). Params: layerName, packagePath?, weightBlended? - create_layer_info: Standalone LayerInfo asset creation - no landscape required. Params: layerName, name? (default LI_<layerName>), packagePath? (default /Game/Landscape/LayerInfos), physMaterial? (asset path), hardness? (#251) - create: Spawn a new ALandscape with a flat heightmap. Defaults match the Editor's Landscape Mode 'create new' (8x8 components, 63 quads/subsection, 2 subsections/component = 1016x1016 quads). Params: location? (Vec3), scale? (Vec3, default 100,100,100), componentCountX? (default 8), componentCountY? (default 8), subsectionSizeQuads? (one of 7|15|31|63|127|255, default 63), numSubsections? (1|2, default 2), heightOffset? (uint16, default 32768 = mid-elevation), label? (#303) - get_material_usage_summary: Per-proxy summary: landscape/hole material paths + component/grass/nanite counts (#150). It is categorised as a Execute tool in the Ue MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ue MCP server in PolicyLayer and add a rule for landscape: 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 Ue. Nothing to install.
landscape is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the landscape 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 landscape. 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.
landscape is provided by the Ue MCP server (ue-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
