Integration patterns for combining Agent-to-Agent (A2A) Protocol with Model Context Protocol (MCP) for hybrid agent communication. Use when building systems that need both agent-to-agent communication and agent-to-tool integration, implementing composite architectures, or when user mentions A2A+MCP integration, hybrid protocols, or multi-agent tool access.

.claude/skills/a2a-mcp-integration/# 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 ## Quick Start ### Python Integration ```bash # Install both SDKs ./scripts/install-python-integration.sh # Validate installation ./scripts/validate-python-integration.sh # Run example python examples/python-hybrid-agent.py ``` ### TypeScript Integration ```bash # Install both SDKs ./scripts/install-typescript-integration.sh # Validate installation ./scripts/validate-typescript-integration.sh # Run example ts-node examples/typescript-hybrid-agent.t
