MOST DANGEROUS TOOLS

High Risk

The most dangerous VRChat MCP OSC tools

Execute · Low jump This tool executes a real-time action (jump) on a VRChat avatar via OSC, triggering an external operation in a virtual environment. Execute · Medium look_direction This tool executes a real-time action in an external VR environment (VRChat), controlling avatar orientation via OSC protocol. Execute · Low menu Toggling a menu is an external action/interaction within VRChat rather than a pure data read or write. Execute · Medium move_avatar This tool triggers an external operation (movement) in a live VRChat environment.

9 of VRChat MCP OSC's 12 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control VRChat MCP OSC

PolicyLayer is an MCP gateway — it sits between your AI agents and VRChat MCP OSC, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "send_message": {
    "limits": [
      {
        "counter": "send_message_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_avatar_list": {
    "limits": [
      {
        "counter": "get_avatar_list_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
