Measure the distance between two objects in a Rhino file.
AI agents call measure_distance to retrieve information from GH_mcp_server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only geometric measurement operation, querying spatial data from a Rhino file without modifying, creating, or deleting any data. It simply returns a distance value between two objects.

Documented attack patterns abuse exactly the kind of access measure_distance gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GH_mcp_server, and nothing reaches the server without passing your rules. This is the rule we recommend for measure_distance:
{
"version": "1",
"default": "deny",
"tools": {
"measure_distance": {}
}
}measure_distance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Measure the distance between two objects in a Rhino file. It is categorised as a Read tool in the GH_mcp_server MCP Server, which means it retrieves data without modifying state.
Register the GH_mcp_server MCP server in PolicyLayer and add a rule for measure_distance: 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 GH_mcp_server. Nothing to install.
measure_distance is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the measure_distance 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 measure_distance. 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.
measure_distance is provided by the GH_mcp_server MCP server (veoery/gh_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
