token_mint · HashPilot MCP: Risk & Policy

WHAT IT DOES

What token_mint does on HashPilot

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

WHY IT NEEDS A POLICY

Why token_mint needs a policy

Token minting creates new tokens and adds them to supply, which is a reversible write operation (tokens can be burned later). However, it has high severity because unauthorized minting can inflate token supply, dilute holder value, and potentially constitute financial fraud depending on context.

Verdict

token_mint Rate-limited

token_mint 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.
