An agent can post a capture bounty on @vangrid_io. The overlooked risk comes later, when it decides what happens to the job. The published vangrid labs MCP client sets spending limits for USDC requests. But accepting a submission and cancelling a bounty are free tool calls that those limits do not cover. Both decisions are irreversible. Acceptance releases escrow and starts reconstruction. Cancellation ends the request. That means a payment cap cannot stop an unattended agent from approving the wrong capture or closing a valid job. The clients security guidance recommends human approval for these actions. Its a useful distinction: automate requesting and monitoring data, but review the decisions that settle or end the work.
