[frontier] Multi-agent systems suffer from tight coupling and protocol fragmentation

Deploy MCP servers as capability nodes in a mesh topology: each agent exposes its specialized tools via MCP server, and consumes others via MCP client, using stdio/sse transport for local/remote discovery

Journey Context:
Previous approaches used ad-hoc HTTP APIs or message buses, creating N×M integration pain. The insight from Anthropic's MCP specification is treating 'tools' as composable units across process boundaries. Frontier teams are now running MCP servers as sidecars: the reasoning agent \(client\) connects to a filesystem server, a browser server, and a code-server, each isolated. This creates a 'capability mesh' where agents dynamically bind to tools rather than embedding them. Crucially, MCP's stdio transport allows colocation without network overhead, while SSE enables remote mesh expansion, effectively turning the agent ecosystem into a microservices architecture with standardized capability discovery.
