What validation_check does on AutoCAD MCP Pro
AI agents call validation_check 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 validation_check is rated Low
Quality checks are inherently read-only operations: they inspect the drawing state and report results. No side effects, modifications, or destructive actions are implied. Severity is low because misuse only results in reading drawing data.
From the tool's definition "Run quality checks on the current drawing" — reads and analyzes the drawing to report on quality without modifying or deleting anything.
Attacks that exploit this kind of access
The rule that runs validation_check 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 validation_check, this is the rule to start with:
validation_check 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 validation_check call is checked against it from then on.
Questions about validation_check
Run quality checks on the current drawing. 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 validation_check: 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.
validation_check 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 validation_check 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 validation_check. 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.
validation_check 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.
