WHAT IT DOES

What get_app does on Tenzro Ledger MCP

AI agents call get_app 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 get_app is rated Low

This tool performs a read-only lookup of app metadata. It retrieves existing data about a registered application without creating, modifying, deleting, or executing any operations. The low severity reflects that disclosure of app metadata (DID, wallet address, public signing keys, status) has minimal blast radius if misused by an AI agent—these are typically semi-public identifiers in a ledger system.

From the tool's definition Tool description states 'Look up a registered app by id' with fields (developer DID, app wallet, signing keys, margin, status) — pure retrieval with no modification or execution.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

get_app Allowed

get_app 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": {
    "get_app": {}
  }
}

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 get_app call is checked against it from then on.
