What entity_get_xdata does on AutoCAD MCP Pro
AI agents call entity_get_xdata to retrieve information from AutoCAD MCP Pro without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why entity_get_xdata is rated Low
Tool queries XDATA attributes from CAD entities without modifying or deleting any data.
From the tool's definition retrieves extended entity data; no side effects

The rule that runs entity_get_xdata safely
PolicyLayer is an MCP gateway: it sits between your AI agents and AutoCAD MCP Pro, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For entity_get_xdata, this is the rule to start with:
entity_get_xdata 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 AutoCAD MCP Pro, apply this rule, and every entity_get_xdata call is checked against it from then on.
Questions about entity_get_xdata
Extended entity data as {app: [values]}. An app with no XDATA is simply absent. It is categorised as a Read tool in the AutoCAD MCP Pro MCP Server, which means it retrieves data without modifying state.
Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for entity_get_xdata: 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 Pro. Nothing to install.
entity_get_xdata 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 entity_get_xdata 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 entity_get_xdata. 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.
entity_get_xdata is provided by the AutoCAD MCP Pro MCP server (u-c4n/autocad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
