Disconnect a specific port on a node in the Amplify Shader Editor graph.
AI agents use unity_amplify_disconnect 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.
This tool modifies shader graph state by disconnecting ports between nodes. While the change is reversible (unlike deletion), it alters the project's shader composition. It falls into Write rather than Execute because it performs a specific data-structure manipulation rather than executing arbitrary code or commands.
From the tool's definition The tool description states it will 'Disconnect a specific port on a node' in the Amplify Shader Editor graph, which modifies the shader graph structure by altering node connections. This is a reversible modification operation (ports can be reconnected).
Documented attack patterns abuse exactly the kind of access unity_amplify_disconnect 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_amplify_disconnect:
{
"version": "1",
"default": "deny",
"tools": {
"unity_amplify_disconnect": {
"limits": [
{
"counter": "unity_amplify_disconnect_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}unity_amplify_disconnect 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.

Disconnect a specific port on a node in the Amplify Shader Editor graph. 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.
Register the Unity MCP Server MCP server in PolicyLayer and add a rule for unity_amplify_disconnect: 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_amplify_disconnect is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the unity_amplify_disconnect 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 unity_amplify_disconnect. 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.
unity_amplify_disconnect 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.
