# A2A and MCP Integration Patterns

**Purpose:** Provide integration patterns, configuration examples, and best practices for combining Agent-to-Agent Protocol with Model Context Protocol in multi-agent systems.

**Activation Triggers:**
- A2A + MCP integration setup
- Hybrid protocol architecture
- Agent-to-agent + agent-to-tool communication
- Composite multi-agent systems
- Protocol compatibility questions
- Cross-protocol authentication
- Combined SDK usage

**Protocol Roles:**
- **A2A Protocol:** Agent-to-agent communication and task delegation
- **MCP:** Agent-to-tool communication and resource access
- **Combined:** Agents communicate via A2A while accessing tools via MCP

## Architecture Overview

### Why Combine A2A and MCP?

A2A and MCP are complementary protocols:

- **MCP** standardizes how agents connect to tools, APIs, and data sources
- **A2A** standardizes how agents communicate and coordinate with each other
- **Together** they enable agents to collaborate while accessing shared resources

### Integration Patterns

1. **Hierarchical Agent Systems**
   - Coordinator agent uses A2A to delegate tasks
   - Worker agents use MCP to access tools
   - Results flow back through A2A

2. **Federated Tool Access**
   - Multiple agents communicate via A2A
   - Each agent has MCP tool access
   - Agents share tool results through A2A messages

3. **Resource-Sharing Networks**
   - Agents discover each other via A2A
   - Agents expose MCP servers to each other
   - Dynamic tool delegation through agent network
