WHAT IT DOES

What set_sponsorship_refill_threshold does on Tenzro Ledger MCP

AI agents use set_sponsorship_refill_threshold to create or update resources in Tenzro Ledger MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tenzro Ledger MCP environment.

RISK

Why set_sponsorship_refill_threshold is rated Medium

This tool modifies configuration state (refill thresholds) for adapter pools, which is reversible and constitutes a Write operation. However, severity is elevated to 'high' because: (1) it requires admin/operator privileges (token-gated access control), (2) it controls financial or resource-related pool parameters (refill thresholds in a payment/wallet system), and (3) misconfiguration could impact system-wide…

From the tool's definition Tool description states it 'Set[s] per-adapter pool refill threshold' and is '(Operator admin-token-gated)', indicating modification of configuration parameters.

RECOMMENDED RULE

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

set_sponsorship_refill_threshold Rate-limited

set_sponsorship_refill_threshold stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
