AI agents use create_component to create or update resources in SketchupMCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SketchupMCP environment.
Creating a component in Sketchup adds new geometry to a model. While reversible (distinguishing it from Destructive category), this modifies project state and could interfere with ongoing work or produce unwanted results if triggered by prompt misinterpretation.
From the tool's definition Tool name 'create_component' and description 'Create a new component in Sketchup' indicate creation of new data structures within a 3D modeling project. This is reversible via undo/delete operations typical in design software.
Documented attack patterns abuse exactly the kind of access create_component gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SketchupMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for create_component:
{
"version": "1",
"default": "deny",
"tools": {
"create_component": {
"limits": [
{
"counter": "create_component_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_component 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 component in Sketchup. It is categorised as a Write tool in the SketchupMCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sketchup MCP server in PolicyLayer and add a rule for create_component: 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 SketchupMCP. Nothing to install.
create_component 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 create_component 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 create_component. 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.
create_component is provided by the Sketchup MCP server (mhyrr/sketchup-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SketchupMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
