[frontier] How do I decouple agent capability discovery from hardcoded tool definitions?

Treat MCP servers as long-lived capability substrates: agents discover and bind to MCP services dynamically using the protocol's roots/sampling primitives, moving beyond static tool registries to a service-mesh architecture for agents.

Journey Context:
Static tool definitions force redeployment when capabilities change and create tight coupling between agent logic and tool implementations. Early MCP adoption treated it as 'better function calling,' but production systems are hitting walls with versioning and cross-team coordination. The shift is treating MCP servers as the 'agentic nervous system'—capabilities are advertised, discovered, and negotiated via the protocol's bidirectional features \(roots, sampling, notifications\). This allows zero-downtime capability updates, A/B testing of tools across agent fleets, and cross-framework interoperability \(LangChain agents using CrewAI tools via MCP\). The tradeoff is operational complexity—you now run a service mesh—but the alternative is agent monoliths that can't evolve.
