To grade the real runtime surface, scan the running server: --command \"npx -y <package>\"."

"description": "This server (without client built-ins) exposes a complete data-exfiltration chain: get_entry_version ⇒ create_webhook → delete_webhook. 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.",
