create_text · 3D MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_text does on 3D MCP Server

AI agents use create_text to create or update resources in 3D MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 3D MCP Server environment.

WHY IT NEEDS A POLICY

Why create_text needs a policy

This tool creates new 3D geometry (extruded text objects) and adds them to a model, which is a reversible modification operation. It does not execute arbitrary commands, delete data irreversibly, or move financial resources. The 'medium' severity reflects that while misuse could create many unwanted objects or consume resources, the effects are reversible through normal model editing/deletion operations.

From the tool's definition Tool description states 'Create 3D extruded text', indicating it generates and adds new 3D model data. The sibling tools include 'create_primitive', 'create_polyhedron', and other creation/modification operations, establishing this as a Write operation within…

Verdict

create_text Rate-limited

create_text 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches 3D MCP Server, so you can run agents against it safely.

FAQ

Questions about create_text

What does the create_text tool do? +

Create 3D extruded text. It is categorised as a Write tool in the 3D MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_text? +

Register the 3D MCP Server MCP server in PolicyLayer and add a rule for create_text: 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 3D MCP Server. Nothing to install.

What risk level is create_text? +

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

Can I rate-limit create_text? +

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

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

create_text is provided by the 3D MCP Server MCP server (jagjerez-org/3d-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
