WHAT IT DOES

What get_credit_balance does on Tanod

AI agents call get_credit_balance to retrieve information from Tanod 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_credit_balance is rated Low

Even though get_credit_balance only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_credit_balance safely

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

get_credit_balance Allowed

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

  "default": "deny",
  "tools": {
    "get_credit_balance": {}
  }

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

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