NYC MyCity chatbot tells businesses to break the law

City of New York / Microsoft · Mar 29, 2024 · Customer service agent

What happened

A Markup investigation found that New York City's Microsoft-powered MyCity Business chatbot advised business owners that employers could legally take workers' tips and landlords could reject Section 8 vouchers - both violations of NYC law. Mayor Adams acknowledged the bot gave wrong answers but the city initially kept it online.

How a spend firewall would have helped

Legal/employment advice is a high-risk category. A category rule flagging ‘legal-claim’ outputs for human review before they reach a citizen turns an unbounded chatbot into an audited advisory channel.

The six rule types that contain this class of failure

Per-transaction cap

Any single spend above your ceiling is BLOCKED before it moves.

Daily total

Cumulative spend across all agent calls, bounded per day.

Velocity limit

Stops runaway retry loops — the #1 cause of overnight losses.

Merchant allowlist

Only approved destinations can ever receive funds.

Category rules

Flag high-risk classes (crypto, infra, refunds) for review.

Approval threshold

Above a value, the action waits for a human.
