unity_navmesh_set_destination

Set the destination for a NavMeshAgent (requires Play mode).

How to control unity_navmesh_set_destination ↓

AI agents invoke unity_navmesh_set_destination to trigger actions in Unity MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

High Risk

This tool triggers runtime behavior in Unity's Play mode by directing a NavMeshAgent to navigate to a destination. It causes active execution of pathfinding and movement logic within the running simulation, qualifying as Execute. It doesn't read data, persistently write assets, destroy data, or involve finances.

Documented attack patterns abuse exactly the kind of access unity_navmesh_set_destination 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_navmesh_set_destination:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "unity_navmesh_set_destination": {
      "limits": [
        {
          "counter": "unity_navmesh_set_destination_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

unity_navmesh_set_destination stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Unity MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What does the unity_navmesh_set_destination tool do? +

Set the destination for a NavMeshAgent (requires Play mode). It is categorised as a Execute tool in the Unity MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on unity_navmesh_set_destination? +

Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_navmesh_set_destination: 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_navmesh_set_destination? +

unity_navmesh_set_destination is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit unity_navmesh_set_destination? +

Yes. Add a rate_limit block to the unity_navmesh_set_destination 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_navmesh_set_destination completely? +

Set action: deny in the PolicyLayer policy for unity_navmesh_set_destination. 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_navmesh_set_destination? +

unity_navmesh_set_destination 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.
