[frontier] Monolithic MCP servers become bloated violating single-responsibility and creating version hell

Design servers as composable primitives where Server A exposes resources consumed by Server B via client-side or server-side delegation using stdio/sse chaining with capability proxying

Journey Context:
Early MCP servers try to do everything \(filesystem \+ git \+ web\). The 2025 realization is that MCP is a microservices protocol. The pattern is chaining: a 'research' server calls a 'browser' server which calls an 'extractor' server. This requires careful handling of capabilities and transitive permissions but enables Unix-philosophy composability where small single-purpose servers combine into complex agent capabilities.
