WHAT IT DOES

What getMaterials does on Spline MCP Server

AI agents call getMaterials 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 getMaterials is rated Low

This tool retrieves material information from Spline designs without modifying, executing, or deleting anything. The 'get' prefix is a standard indicator of read-only data retrieval. Even in a 3D design context, querying materials poses minimal risk compared to tools that create, apply, or delete design elements.

From the tool's definition Tool name 'getMaterials' indicates retrieval of material data. The description is empty, but naming convention and context of sibling tools (which perform modifications like 'add' operations) strongly suggest this is a query operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs getMaterials 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 getMaterials, this is the rule to start with:

getMaterials Allowed

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

policy.json

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

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 getMaterials call is checked against it from then on.
