mint_nft · Tenzro Ledger MCP: Risk & Policy

WHAT IT DOES

What mint_nft does on Tenzro Ledger MCP

AI agents use mint_nft 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 mint_nft needs a policy

Minting an NFT creates a new on-chain asset and assigns it to a recipient. This is a Write operation (creates new data/assets on a blockchain). While it involves blockchain state changes and potentially gas costs, it does not directly move money or commit financial obligations in the traditional sense (no payment transfer), though it could have financial implications.
