Create a mortise and tenon joint between two components
AI agents use create_mortise_tenon 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.
This tool creates/modifies 3D geometry in SketchUp by establishing a joinery connection between components. It writes new geometric data to the scene, which is reversible (components can be deleted or modified). No code execution, deletion, or financial activity is involved.

Documented attack patterns abuse exactly the kind of access create_mortise_tenon 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_mortise_tenon:
{
"version": "1",
"default": "deny",
"tools": {
"create_mortise_tenon": {
"limits": [
{
"counter": "create_mortise_tenon_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_mortise_tenon 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 mortise and tenon joint between two components. 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_mortise_tenon: 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_mortise_tenon 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_mortise_tenon 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_mortise_tenon. 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_mortise_tenon 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.
Free to start. No card required.
