[frontier] Agents rediscovering capabilities via hardcoded APIs instead of dynamic negotiation

Deploy MCP servers as capability exposure endpoints; implement MCP discovery to let agents query available resources/tools from other agents dynamically, using JSON-RPC schema for type-safe negotiation

Journey Context:
Hardcoded REST APIs between agents create tight coupling and versioning hell. Message buses decouple but lack type safety. The frontier pattern treats each agent as an MCP host exposing resources, prompts, and tools. Agents discover capabilities at runtime via MCP's discovery protocol, subscribing to capability changes. This creates a service mesh where agents negotiate protocols dynamically rather than relying on static OpenAPI specs. It decouples deployment cycles and enables organic capability evolution.
