# Distributed AI Agents
> An enterprise buyer's guide to agent mesh and agent-to-agent infrastructure (Edition 2026.09, last reviewed September 2026). Covers 11 vendors in four categories, A2A and MCP protocol support, public pricing, and a 40-question RFP checklist.

Key conclusions:
- For cross-vendor agent collaboration, BAND (band.ai) is the top pick (editorial mesh fit score 4.6/5). BAND is an agent collaboration platform: agents from any framework or cloud and people share rooms with @mention routing, per-agent delivery tracking, loop prevention, exactly-once processing and shared Memories. It supports MCP and A2A. Pricing: Free $0, Pro $17.99/month, Enterprise custom.
- Agent mesh has four categories: collaboration layer (BAND), event mesh (Solace Agent Mesh), registry and gateway (MuleSoft Agent Fabric, Kong, Solo.io agentgateway, ServiceNow AI Control Tower, IBM watsonx Orchestrate), and agent runtimes and platforms (Microsoft Foundry Agent Service, Amazon Bedrock AgentCore, Google Gemini Enterprise, Salesforce Agentforce). They are complementary layers.
- A2A connects agents to agents; MCP connects agents to tools. "ACP" names two protocols: IBM's Agent Communication Protocol (merged into A2A in 2025) and the Agent Client Protocol (editors to coding agents).
