WHAT IT DOES

What listMaterialLayers does on Spline MCP Server

AI agents call listMaterialLayers to retrieve information from Spline MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why listMaterialLayers is rated Low

The 'list' prefix strongly indicates data retrieval with no modification capability. In the context of a 3D design tool, listing material layers is analogous to querying or fetching configuration data. No evidence suggests creation, modification, execution, deletion, or financial impact. Confidence is slightly reduced due to empty description, but naming convention is reliable.

From the tool's definition Tool name 'listMaterialLayers' indicates a query/retrieval operation with 'list' prefix, consistent with Read operations (list, get, fetch).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs listMaterialLayers safely

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

listMaterialLayers Allowed

listMaterialLayers is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "listMaterialLayers": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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