AI agents call analyze_rhino_file 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.
The verb 'analyze' combined with 'file' in this CAD/3D modeling context means examining, inspecting, or querying the structure and contents of a .3dm file. There is no indication of code execution (like execute_grasshopper_code on the same server), modification of the file, deletion, or financial operations. This is a read-only query/inspection tool with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'analyze_rhino_file' and description 'Analyze a Rhino (.3dm) file' indicate retrieval and inspection of file contents without modification or execution of external operations.
Documented attack patterns abuse exactly the kind of access analyze_rhino_file 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 analyze_rhino_file:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_rhino_file": {}
}
}analyze_rhino_file is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Analyze a Rhino (.3dm) 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 analyze_rhino_file: 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.
analyze_rhino_file 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 analyze_rhino_file 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 analyze_rhino_file. 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.
analyze_rhino_file 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.
