[frontier] How do I make agents built with different frameworks collaborate without custom integrations?

Use Google's A2A protocol for agent-to-agent discovery, delegation, and negotiation; use Anthropic's MCP only for tool/resource access. Treat A2A as the org-chart layer and MCP as the hands layer. Expose Agent Cards for capability discovery and keep tool servers stateless.

Journey Context:
Most teams currently either force every agent into one framework, creating vendor lock-in, or write brittle point-to-point HTTP wrappers. A2A standardizes peer-to-peer collaboration \(announced April 2025 with 50\+ partners including Microsoft, Salesforce, SAP\), while MCP standardizes tool access. The wrong call is using MCP for inter-agent chat or A2A for tool invocation; each solves a different layer. The right separation lets agents from different vendors form dynamic teams.
