Get detailed information about an STL file
AI agents call get_stl_info to retrieve information from MCP 3D Printer Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata or properties from an STL file without creating, modifying, deleting, or executing any operations. It is a passive read operation similar to 'get' or 'fetch' operations, presenting minimal risk even if misused by an agent, as it cannot cause side effects beyond information disclosure.
From the tool's definition Tool name 'get_stl_info' and description 'Get detailed information about an STL file' indicate a query/retrieval operation with no modification or execution capability.
Attacks that exploit this kind of access
Get detailed information about an STL file. It is categorised as a Read tool in the MCP 3D Printer Server MCP Server, which means it retrieves data without modifying state.
Register the MCP 3D Printer Server MCP server in PolicyLayer and add a rule for get_stl_info: 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 MCP 3D Printer Server. Nothing to install.
get_stl_info 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 get_stl_info 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 get_stl_info. 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.
get_stl_info is provided by the MCP 3D Printer Server MCP server (mcpflow/dmontgomery40_mcp-3d-printer-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
