Postman's Silent AI Plugin Push: How an API Tool Became a Trust Liability

When a Trusted API Client Starts Exfiltrating Your Data

According to community reports surfacing across Reddit and Hacker News, Postman — long the de facto standard for API development and testing — has begun silently auto-installing AI plugins and attempting to share API data without explicit user consent. For a tool whose entire value proposition rests on handling sensitive request payloads, authentication tokens, and internal endpoint structures, the prospect of unsolicited data egress represents a fundamental breach of the implicit contract between tool and developer. The timing is no accident: Postman has spent the past two years aggressively repositioning itself around AI-assisted workflows, and this push appears to be the latest escalation in a monetization strategy that critics argue has prioritized feature expansion over the lean reliability that originally drove its adoption. Technically, the issue is compounded by the opt-out (rather than opt-in) nature of these features, which runs directly counter to the privacy-by-default expectations that increasingly govern developer tooling in 2026.
