AIR raises $50M to vet agent add-ons

AIR emerged from stealth with $50 million across two seed rounds to vet the skills, plug-ins, and MCP servers that enterprise AI agents load. TechCrunch’s funding report says its platform currently filters about 27% of add-ons and skills it finds online and has more than 20 customers; those are company figures, not an independent threat-rate estimate. Builders letting agents install tools should treat continuous re-verification as a control-plane requirement, extending the archive’s analysis of agent-skill retrieval beyond discovery into enforcement.
