"description": "This server (without client built-ins) exposes a complete data-exfiltration chain: bluesky__trending_get ⇒ datadog__logs_view → venmo__payment_request. Untrusted input is ingested, private data is read, and it can be sent to an external sink — and at least one leg is a direct schema wire (⇒), where a producer's output drops straight into a free-text parameter of the next tool, so the chain needs little agent cooperation. Static analysis proves the primitive exists, not that a specific run will occur.",
