Registry Agent

An Agent Development Kit (ADK) TypeScript agent that interacts with the Tech Lab agent registry MCP server. It helps you browse entries, search the registry, and get details about registered agents and MCP servers.

Prerequisites

• Node.js 24.13.0 or later
• npm 11.8.0 or later

Setup

1. Install dependencies

From the registry-agent directory:

npm install

2. Configure environment variables

Copy the example env file and edit it with your values:

cp .env.example .env

Edit .env and set:

Variable	Description
GEMINI_API_KEY	Your Gemini API key (required for the ADK agent).
REGISTRY_MCP_URL	URL of the Tech Lab agent registry MCP server.
REGISTRY_MCP_TOKEN	Bearer token for registry MCP authentication.

Example:

GEMINI_API_KEY="your-gemini-api-key"
REGISTRY_MCP_URL="https://your-registry-mcp-server.example.com"
REGISTRY_MCP_TOKEN="your-token-here"

Run the agent

Command-line interface:

npx adk run agent.ts

Web interface (development only, not for production):

npx adk web

Then open http://localhost:8000, select the agent, and chat.
