WHAT IT DOES

What pid_graph does on AutoCAD MCP Pro

AI agents use pid_graph to create or update resources in AutoCAD MCP Pro, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AutoCAD MCP Pro environment.

RISK

Why pid_graph is rated Medium

An AI agent can call pid_graph faster than any human can review: one bad instruction and it creates or modifies resources in AutoCAD MCP Pro by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

pid_graph Rate-limited

pid_graph stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

How do I enforce a policy on pid_graph? +

Register the AutoCAD MCP Pro MCP server in PolicyLayer and add a rule for pid_graph: 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 pid_graph? +

pid_graph is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit pid_graph? +

Yes. Add a rate_limit block to the pid_graph 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 pid_graph completely? +

Set action: deny in the PolicyLayer policy for pid_graph. 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 pid_graph? +
