AI agents call scan_all_entities to retrieve information from AutoCAD MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool scans and reads existing entities from an AutoCAD drawing. While it stores results in a database, the core operation is retrieving and cataloging data without modifying the drawing itself. This is a passive information-gathering operation with no side effects on the drawing or entities, fitting the Read category.
From the tool's definition Tool name 'scan_all_entities' and description '扫描当前图纸中的所有实体并保存到数据库' (scan all entities in current drawing and save to database) indicate retrieval and enumeration of existing drawing objects. The action is querying/reading entities from the current drawing.
Documented attack patterns abuse exactly the kind of access scan_all_entities gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AutoCAD MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for scan_all_entities:
{
"version": "1",
"default": "deny",
"tools": {
"scan_all_entities": {}
}
}scan_all_entities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

扫描当前图纸中的所有实体并保存到数据库. It is categorised as a Read tool in the AutoCAD MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AutoCAD MCP Server MCP server in PolicyLayer and add a rule for scan_all_entities: 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 AutoCAD MCP Server. Nothing to install.
scan_all_entities 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 scan_all_entities 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 scan_all_entities. 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.
scan_all_entities is provided by the AutoCAD MCP Server MCP server (zh19980811/easy-mcp-autocad). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
