Add Web Search to Managed Deep Agents for free with One MCP Config
From the video description
Nathan Drezner, PM at LangChain, shows how to add web search to a managed deep agent. LangSmith includes built-in search powered by Parallel, so it takes one MCP connection with no extra authentication. He asks a research agent a question its internal docs can't fully answer, adds the search server, then deploys to LangSmith and inspects the search tool calls in LangSmith Studio.
