Why blender_api_docs needs a policy

This tool performs read-only documentation lookup. It retrieves and queries reference information about Blender's Python API without creating, modifying, executing code, or causing any irreversible changes. The action is purely informational and carries minimal risk in the context of AI agent misuse.

From the tool's definition Tool description states 'Look up Blender Python API documentation for an identifier' — a straightforward documentation retrieval operation with no side effects.

How to control blender_api_docs

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "blender_api_docs": {}
  }
}

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

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