2o

When your AI agent needs to verify a claim or check a fact with an actual human expert, this server connects to the 2o API to route questions to domain specialists. It's designed for scenarios where you want ground truth from people rather than model inference, like validating technical specifications, checking industry regulations, or confirming current real-world conditions. The server runs over stdio or SSE and gives Claude a way to escalate uncertain queries to human verification before proceeding. Useful when accuracy matters more than speed and you need a human in the loop without building your own expert network.
