WHAT IT DOES

What block_find_references does on AutoCAD MCP Pro

AI agents call block_find_references 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.

RISK

Why block_find_references is rated Low

This tool retrieves metadata about where a block is referenced within a drawing. It performs a read-only search across the drawing model to locate references to a specified block definition. No data is created, modified, deleted, or executed—only existing references are queried and reported.

From the tool's definition Tool name 'block_find_references' and description 'Find all insert references to a specific block definition' indicate a query/search operation that retrieves information about block references without modifying or executing operations.

RECOMMENDED RULE

The rule that runs block_find_references 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 block_find_references, this is the rule to start with:

block_find_references Allowed

block_find_references is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "block_find_references": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect AutoCAD MCP Pro, apply this rule, and every block_find_references call is checked against it from then on.
