WHAT IT DOES

What generate_object_url does on Linode MCP Server

AI agents call generate_object_url to retrieve information from Linode 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 generate_object_url is rated Low

Generating a pre-signed URL is a read operation that creates a temporary access URL without modifying the underlying object. However, it has medium severity because pre-signed URLs grant access to objects that may be private, potentially exposing sensitive data if misused by an AI agent.

RECOMMENDED RULE

The rule that runs generate_object_url safely

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

generate_object_url Allowed

generate_object_url 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": {
    "generate_object_url": {}
  }
}

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

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