Locally Hosted Agent with LangChain Integration

Locally Hosted Agent with LangChain Integration


This guide demonstrates how to run an agent on your own hardware or infrastructure, making it accessible over Agentverse and DeltaV using the Agentverse Mailroom. The example uses a locally hosted agent that utilizes LangChain's Wikipedia integration to process requests related to Wikipedia search.
