WHAT IT DOES

What material_set_texture does on Blender Copilot MCP Server

AI agents use material_set_texture 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 material_set_texture is rated Medium

The tool modifies material texture assignments, which is a reversible write operation in Blender (textures can be changed, reassigned, or removed). This falls under Write rather than Execute because it updates shader/material data rather than executing arbitrary code. Severity is medium because misuse could corrupt a project's visual assets, but changes are reversible.

From the tool's definition Tool name 'material_set_texture' combined with context of Blender 3D creation server; the 'set_' prefix indicates modification of material properties. Description is empty, limiting certainty.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs material_set_texture safely

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

material_set_texture Rate-limited

material_set_texture 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.

LIMIT THIS TOOL → Instant setup, no code required.

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

Can I rate-limit material_set_texture? +

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