WHAT IT DOES

What cluster_preview does on Tenzro Ledger MCP

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

RISK

Why cluster_preview is rated Low

The name 'cluster_preview' implies inspection or retrieval of cluster information without modification. However, confidence is reduced due to the lack of a descriptive description. Without explicit documentation, the tool could potentially involve querying data (Read category) or triggering operational checks (Execute category).

From the tool's definition Tool name 'cluster_preview' suggests a read-only preview operation; description is empty, providing no direct evidence of function.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs cluster_preview safely

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

cluster_preview Allowed

cluster_preview 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": {
    "cluster_preview": {}
  }
}

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

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