Why block_get_attributes needs a policy

The 'get_' prefix and context of sibling tools (analysis_*, block_explode which decomposes) indicate this retrieves attribute data from AutoCAD block objects without modifying state. Absence of description lowers confidence slightly, but the read semantics are clear from nomenclature. No write, execute, or destructive operations are implied.

From the tool's definition Tool name 'block_get_attributes' suggests retrieval of block attributes; naming convention aligns with read-only query patterns on this server (analysis_*, block_explode). No description provided.

POLICY

How to control block_get_attributes

PolicyLayer is an MCP gateway — it sits between your AI agents and AutoCAD MCP Pro, and nothing reaches the server without passing your rules. This is the rule we recommend for block_get_attributes:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "block_get_attributes": {}
  }
}

block_get_attributes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register AutoCAD MCP Pro — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about block_get_attributes

What does the block_get_attributes tool do? +

block_get_attributes. It is categorised as a Read tool in the AutoCAD MCP Pro MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on block_get_attributes? +

Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for block_get_attributes: 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.

What risk level is block_get_attributes? +

block_get_attributes is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit block_get_attributes? +

Yes. Add a rate_limit block to the block_get_attributes 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.

How do I block block_get_attributes completely? +

Set action: deny in the PolicyLayer policy for block_get_attributes. 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.

What MCP server provides block_get_attributes? +

block_get_attributes 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.

Enforce policy on every AutoCAD MCP Pro tool call.

Start from AutoCAD MCP Pro, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
