Field notes

The homepage separates reporting from threat-hunting material and practical playbooks, with source links attached to the visible items. Its MCP research summary gives the study’s scale—3,405 tools across 273 runnable servers—and explicitly notes that the preprint has not been peer-reviewed. The adjacent AI-agent investigation summary also includes attribution caveats, including that the model behind the agents remains unknown.
