WHAT IT DOES

What set_secure_mint_policy does on Tenzro Ledger MCP

AI agents use set_secure_mint_policy 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.

WHY IT NEEDS A POLICY

Why set_secure_mint_policy needs a policy

This tool modifies policy configuration reversibly (policies can be updated again), placing it in Write rather than Execute or Destructive. However, severity is high because misconfigured mint policies on a financial ledger system could enable unauthorized token creation or financial loss if an agent sets permissive policies.

From the tool's definition Tool name 'set_secure_mint_policy' and description 'Set or update a Secure-Mint policy' indicate creation/modification of policy data. The incomplete description ('Enforces') suggests this creates or updates security policies for minting operations.
