What get_entity_topology does on Pypi:best Cad
AI agents call get_entity_topology to retrieve information from Pypi:best Cad without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_entity_topology is rated Low
This tool retrieves geometric and topological information about CAD entities (points, lines, faces, and their relationships). It performs data retrieval only—no creation, modification, deletion, or execution of external operations. The verb '获取' (get/retrieve) confirms read-only semantics. Severity is low because querying entity topology poses minimal risk even if invoked by an AI agent without restrictions.
From the tool's definition Tool name 'get_entity_topology' and description '获取单个实体派生出的点、线、面与拓扑关系' (retrieve topology relationships, points, edges, faces derived from a single entity) indicate a query/retrieval operation with no modification or execution side effects.
Attacks that exploit this kind of access
The rule that runs get_entity_topology safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Pypi:best Cad, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_entity_topology, this is the rule to start with:
get_entity_topology is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Pypi:best Cad, apply this rule, and every get_entity_topology call is checked against it from then on.
Questions about get_entity_topology
获取单个实体派生出的点、线、面与拓扑关系。. It is categorised as a Read tool in the Pypi:best Cad MCP Server, which means it retrieves data without modifying state.
Register the Pypi:best Cad MCP server in PolicyLayer and add a rule for get_entity_topology: 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 Pypi:best Cad. Nothing to install.
get_entity_topology 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_entity_topology 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_entity_topology. 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_entity_topology is provided by the Pypi:best Cad MCP server (pypi:best-cad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
