AI agents call count_text_patterns 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 verb 'count' indicates data retrieval or analysis rather than creation (Write), execution of arbitrary operations (Execute), or data deletion (Destructive). While the empty description reduces confidence slightly, the tool name itself strongly implies a non-destructive query operation. Even if it counts text in drawings, this is fundamentally a read operation with no side effects on the drawing data itself.
From the tool's definition Tool name 'count_text_patterns' suggests a query operation that counts or analyzes text patterns without modifying data.
Documented attack patterns abuse exactly the kind of access count_text_patterns 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 count_text_patterns:
{
"version": "1",
"default": "deny",
"tools": {
"count_text_patterns": {}
}
}count_text_patterns is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

count_text_patterns. 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 count_text_patterns: 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.
count_text_patterns 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 count_text_patterns 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 count_text_patterns. 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.
count_text_patterns 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.
