Report #41294

[frontier] Multi-agent systems fail to interoperate due to tight coupling to specific framework protocols \(LangChain, CrewAI, etc.\) preventing polyglot agent swarms

Deploy Model Context Protocol \(MCP\) servers as the universal interface layer: each agent exposes its capabilities as MCP tools, and consumes other agents' capabilities via MCP clients, enabling agents written in different languages/frameworks to discover and invoke each other through the standardized MCP transport

Journey Context:
Framework-specific A2A \(agent-to-agent\) protocols create silos. REST APIs require tight coupling and manual documentation. MCP was designed for tool-calling, but its schema-based capability discovery and JSON-RPC transport make it ideal for A2A: Agent A exposes 'search\_code' via MCP, Agent B \(in a different language\) discovers it via MCP introspection and calls it. This decouples the 'what' \(capability\) from the 'how' \(implementation language\), enabling true polyglot swarms.
