WHAT IT DOES

What veto_outcome does on Basis MCP Server

AI agents invoke veto_outcome to trigger actions in Basis MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why veto_outcome is rated High

This tool triggers an administrative action that overrides or cancels a proposed prediction market outcome. While not moving money directly, it alters the state of an active prediction market in a potentially irreversible way (vetoing an outcome can invalidate bets, affect payouts, and change market resolution).

RECOMMENDED RULE

The rule that runs veto_outcome safely

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

veto_outcome Rate-limited

veto_outcome stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
