Integration of Google's A2A (Agent to Agent) protocol and MCP Model Context Protocol with Selenium for automated web browsing, test validation, screen capture, and other web-related tasks. The implementation provides flexible deployment options and powerful multi-agent workflow capabilities.
A2AJava is the Java implementation of the Google A2A protocol you can check the project here .

• Web automation using Selenium WebDriver
• Flexible deployment modes:
  • Local A2A task execution
  • Remote 8-Way server integration
• Screenshot capture and validation
• Multi-agent workflow support
• Integration with other agents (e.g., Kafka, lock capture)

The system is built using Spring Boot and follows a modular architecture:

1. Web Browsing Agent: Handles Selenium-based web automation
2. Agent Card Controller: Manages agent capabilities and real-time communication
3. Selenium A2A Controller: Processes JSON-RPC requests for web automation
4. Task Management: Supports both local and remote task execution

• Java 18 or higher
• Maven
• Chrome/Chromium browser

1. Clone the repository
2. Install dependencies:

mvn install

Configure the application using tools4ai.properties:

##Gemini related settings
gemini.modelName=gemini-2.0-flash-001
gemini.location=us-central1
gemini.projectId=cookgptserver

##Anthropic related settings
anthropic.modelName=claude-3-haiku-20240307

Create a web action file (web.action):

go to website https://the-internet.herokuapp.com
click on A/B Testing
save screenshot as "the-internet.herokuapp.com.png"

Run the agent:

LocalA2ATaskClient client = context.getBean(LocalA2ATaskClient.class);
FilePart filePart = new FilePart();
// ... setup file content
Task t = client.sendFileTask(filePart);

Monitor task execution through the web interface:

The system supports real-time updates through WebSocket:

The following diagram illustrates the event flow in the system:

Example of local task execution:

Here are sample test execution results:

{"method":"tools/call","params":{"name":"browseWebAndReturnImage","arguments":{"provideAllValuesInPlainEnglish":"Go to Google.com, search for \"a2ajava\", wait for results to load, click on the first search result link, wait for the page to load completely, then take a screenshot of the page"}},"jsonrpc":"2.0","id":17}

{"method":"tools/call","params":{"name":"browseWebAndReturnText","arguments":{"provideAllValuesInPlainEnglish":"Go to Google.com, search for \"a2ajava\"give me result"}},"jsonrpc":"2.0","id":17}
