Managed Deep Agents: Adding Custom Python/TypeScript Tools

Learn how to define and register custom tools for LangChain's Managed Deep Agents in just a few steps.

Ready to give your AI agents superpowers? In just a few lines you can attach any Python or TypeScript function as a tool.

⚡ TL;DR: Learn how to define custom tools, import them into agent.py, and feed them to define_deep_agent for Managed Deep Agents.

The Simple Version

Think of a tool as a special function that the agent can call.

You write the function, put it in your project, and tell the agent about it.

How It Actually Works

🎯 Think of it this way: A tool is like a remote control that lets the agent operate devices in the world.

Define Your Tool

Create a function that does the work you need.

Make sure it follows the expected signature.

Import and Register

Put the function in agent.py.

Pass it to define_deep_agent so the system knows it exists.

Technical Deep Dive

Managed Deep Agents expects tools to be exported as objects in a tools dictionary.

Each entry maps a name to a callable that matches the Callable protocol.

You can also provide TypeScript definitions for front‑end integration.

The agent runtime serializes calls, sends them over the network, and returns results.

Why This Matters

Custom tools let you connect LLMs to databases, APIs, or hardware without rebuilding the whole stack.

Developers can reuse existing code, speeding up prototyping and production deployment.

This extensibility is key for building real‑world AI applications.

Key Takeaways

  • Define a function that encapsulates the desired capability.
  • Import it into agent.py.
  • Pass the tool list to define_deep_agent.
  • Tools can be written in Python or TypeScript.
  • Managed Deep Agents handles the call‑remote‑execution plumbing.
  • This pattern enables rich, interactive AI agents.
  • Start small, then scale to complex workflows.
