WHAT IT DOES

What vrc_export_fbx does on Blender Copilot MCP Server

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

RISK

Why vrc_export_fbx is rated Medium

Export operations create or modify files on the file system, which is a Write category action. Severity is high because exporting avatar data could overwrite existing files or commit 3D assets to formats ready for distribution/upload, with potential for unintended data loss if misused by an agent.

From the tool's definition Tool name 'vrc_export_fbx' indicates export functionality that writes FBX files to disk, typical of Blender's file output operations.

RECOMMENDED RULE

The rule that runs vrc_export_fbx safely

vrc_export_fbx Rate-limited

vrc_export_fbx 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.
