Create a new Amplify Shader Editor shader file with proper ASE serialization markers. The shader can then be opened in ASE for visual editing.
AI agents use unity_amplify_create_shader 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.
The tool creates new shader files (irreversible in the sense that the action occurred, but the file itself can be deleted). This is a Write operation—it produces new data artifacts in the project that can be modified or removed.
From the tool's definition Creates a new shader file with ASE serialization markers. Shader creation is a reversible data operation that generates new assets in the Unity project.
Documented attack patterns abuse exactly the kind of access unity_amplify_create_shader 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_create_shader:
{
"version": "1",
"default": "deny",
"tools": {
"unity_amplify_create_shader": {
"limits": [
{
"counter": "unity_amplify_create_shader_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}unity_amplify_create_shader 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.

Create a new Amplify Shader Editor shader file with proper ASE serialization markers. The shader can then be opened in ASE for visual editing. 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_create_shader: 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_create_shader 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_create_shader 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_create_shader. 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_create_shader 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.
