Oap Langgraph Tools Agent

Open Agent Platform LangGraph Tools Agent

A pre-built LangGraph tools agent for Open Agent Platform. It contains support for MCP servers and a LangConnect RAG tool.

[!TIP] This project is built for [Open Agent Platform](https://github.com/langchain-ai/open-agent-platform), a citizen developer platform for building, testing, and using agents.

Setup

First, clone the repository and create a new virtual environment:

git clone https://github.com/langchain-ai/oap-langgraph-tools-agent.git

uv venv

Activate the virtual environment:

source .venv/bin/activate

Install dependencies:

uv sync

Then set the environment variables:

cp .env.example .env

This project requires a Supabase account with authentication to be setup. This is because this project implements custom LangGraph authentication so that it can be called directly from a web client.

After setting your environment variables, you can start the server by running:

# The --no-browser will disable auto-opening LangGraph studio when the server starts
# optional, but recommended since the studio is not needed for this project
uv run langgraph dev --no-browser

The server will now be running on `http://localhost:2024`.

Open Agent Platform

This agent has been configured to work with the [Open Agent Platform](https://github.com/langchain-ai/open-agent-platform). Please see the [OAP docs](https://github.com/langchain-ai/open-agent-platform/tree/main/README.md) for more information on how to add this agent to your OAP instance.

To update the OAP configuration, you can modify the `GraphConfigPydantic` class in the `agent.py` file. OAP will automatically register any changes to this class. You can modify a specific field's properties by editing the `x_oap_ui_config` metadata object. For more information, see the [Open Agent Platform documentation on graph configuration](https://github.com/langchain-ai/open-agent-platform/?tab=readme-
