WHAT IT DOES

What ai_chat does on Blender

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

RISK

Why ai_chat is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs ai_chat safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Blender, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ai_chat, this is the rule to start with:

ai_chat Rate-limited

ai_chat 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.

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