[frontier] How do production agents discover and invoke capabilities from other agents without tight coupling?

Expose agent capabilities via MCP servers using the \`tools/list\` and \`resources/templates\` endpoints, allowing other agents to discover and invoke them through the standardized MCP client interface, effectively using MCP as an inter-agent bus.

Journey Context:
Custom REST/GRPC contracts between agents create brittle coupling—change one endpoint and the consumer breaks. Frontier teams are treating MCP as an 'agent bus' where capability providers expose schemas dynamically. The hard-won insight is that MCP's schema-on-read approach decouples provider from consumer, unlike code-generated stubs. Tradeoff: adds ~50-100ms latency for capability discovery, but gains polyglot interoperability and version resilience.
