AI Agent Tutorials & Implementations

A comprehensive collection of production-ready AI agent implementations showcasing different frameworks, protocols, and integration patterns. This repository demonstrates various approaches to building intelligent agents with Model Context Protocol (MCP), multi-agent systems, and real-world integrations.

Repository Overview

This repository contains four distinct agent implementations, each demonstrating different architectural patterns and use cases:

Project	Framework	Key Features	Use Case
agent2agent	LangGraph + A2A Protocol	Remote agent communication, Slack integration	Investment research
mcp-financial	FastMCP + FastAPI	ASGI integration, CLI client	Financial data analysis
zapier-mcps	OpenAI Agent SDK	Multi-agent handoffs, Zapier integration	Sales operations automation
bright-mcp-server-overview	Dual: LangGraph + ADK	Memory persistence, extended timeouts	Web scraping & research

• Meeting scheduling coordination
• Workflow orchestration
• Multi-agent task delegation

bright-mcp-server-overview/

Bright Data MCP Research Agent

A comprehensive research agent powered by Bright Data's web scraping infrastructure, featuring dual AI agent implementations.

Key Features:

• Dual Framework: LangGraph (with memory) + Google ADK (with extended timeouts)
• Integration: Bright Data MCP server for web scraping
• Slack Interface: Interactive agent selection via dropdown
• Memory: Persistent conversation memory (LangGraph)
• Timeouts: Extended timeout handling (ADK) for long operations
• Specialization: SEO research, e-commerce intelligence, market analysis

Technical Stack:

• LangGraph Agent: OpenAI GPT with MemorySaver checkpointer
• ADK Agent: Google Gemini 2.0 Flash with custom timeout patches
• MCP Integration: Bright Data MCP server for data collection
• Slack Integration: Bot with agent selection and interactive UI

Agent Comparison:

Feature	LangGraph Agent	ADK Agent
Memory	Persistent (checkpointer)	Context-aware (5 messages)
Timeout	Standard (5s)	Extended (60s)
Model	OpenAI GPT	Gemini 2.0 Flash
Best For	Interactive conversations	Long-running operations

Use Cases:

• SEO keyword research and SERP analysis
• E-commerce product monitoring and price tracking
• Competitor analysis and market intelligence
• Web scraping and data collection
• Business intelligence and insights

Getting Started

Each project includes comprehensive setup instructions in its respective README file. General prerequisites include:

Common Requirements

• Python 3.9+
• Valid API keys for respective services
• Slack workspace access (for Slack integrations)
• Environment variable configuration

Quick Start Pattern

# 1. Navigate to desired project
cd [project-name]/

# 2. Install dependencies
pip install -r requirements.txt

# 3. Configure environment
cp .env.example .env
# Edit .env with your API keys

# 4. Run the agent
# (varies by project - see individual READMEs)

Architecture Patterns

Model Context Protocol (MCP)

Three projects demonstrate different MCP implementation patterns:

• FastMCP ASGI: Direct FastAPI integration
• Bright Data MCP: External MCP server communication
• Zapier MCP: Third-party service integration

Agent Communication

• A2A Protocol: Remote agent-to-agent communication
• Multi-Agent Handoffs: Intelligent task delegation
• State Management: Persistent conversation memory

Integration Patterns

• Slack Bots: Event-driven chat interfaces
• CLI Clients: Command-line agent interaction
• FastAPI Servers: RESTful agent endpoints
• Container Deployment: Docker and cloud-ready
