Demo Langdock A2A Agent

This repo is a sample of a simple implementation of an A2A agent compatible with Langdock's implementation of the A2A protocol.

Requirements

The following is needed to run / experiment with this repo:

1. Langdock Account & API key with access to the Agent API

2. Node.js (v18 or higher recommended)

brew install node

3. pnpm package manager

brew install pnpm

4. ngrok for tunneling

brew install ngrok

Getting Started

1. Tunnel the server port with ngrok

ngrok http 3333

2. Install dependencies and run dev server with your ngrok URL

AGENT_URL=https://<your-ngrok-url>.ngrok-free.app pnpm d

3. Copy the Url from the Terminal output

4. Open Langdock and "add integration" -> "start from scratch" -> "Connect Remote Agent (A2A)" -> paste the copied url into the input field:

• Run this command (in a different terminal) to open the langdock integrations page:

pnpm langdock

5. Create a Connection to the Agent

Just use an langdock api-key with the Agent API Scope, it will be forwarded to the A2A

(Optionally) Open the A2A Inspector to test your agent:

pnpm inspector
