WHAT IT DOES

What list_apps does on Tenzro Ledger MCP

AI agents call list_apps 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 list_apps is rated Low

This tool retrieves and queries data from an on-chain app registry without modifying, deleting, or executing any operations. It is a straightforward data retrieval function with no capability to alter state or trigger external actions. The blast radius of misuse is minimal—an agent could only enumerate registered apps.

From the tool's definition Tool name is 'list_apps' and description states it 'List all apps registered in the on-chain app registry'. The verb 'list' indicates a read-only query operation with no side effects.

RECOMMENDED RULE

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

list_apps Allowed

list_apps 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": {
    "list_apps": {}
  }
}

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 list_apps call is checked against it from then on.
