Managed Deep Agents

Overview

Managed Deep Agents is an API-first hosted runtime for creating, running, and operating Deep Agents in LangSmith. It packages the operational layer around the open-source Deep Agents harness — versioned agent repo in the Context Hub, durable threads, streamed runs, managed file tree, MCP credential storage — so you don't have to stand up your own agent server.

For self-hosted deployments or full Agent Server APIs, use a standard LangSmith Deployment via [[langgraph-cli]] instead.

When to use

Use this skill when the user wants to:

• Create or update a Managed Deep Agent (POST / PATCH /v1/deepagents/agents)
• Run an agent on a durable thread and stream the result
• Register or rotate MCP server credentials for an agent's tools
• Configure per-tool human-in-the-loop interrupts on a managed agent
• Decide between Managed Deep Agents and a self-hosted LangSmith Deployment
