[frontier] Type-unsafe agent-to-agent communication causing runtime schema mismatches

Use Model Context Protocol \(MCP\) not just for tools but as a schema registry; define agent capabilities as typed resources and expose them via MCP servers to enforce contracts between agents, using JSONSchema for strict validation.

Journey Context:
Ad-hoc JSON passing between agents leads to 'garbage in, garbage out' failures that only surface in production. MCP provides a typed interface layer similar to gRPC for LLM contexts, allowing agents to discover and validate schemas at connection time rather than runtime. Alternative REST APIs lack context threading and type safety. Tradeoff: MCP adds initial overhead and requires maintaining server endpoints, but eliminates entire classes of integration bugs and enables hot-swapping agent implementations without breaking downstream consumers.
