Report #100845

[frontier] MCP is only for local tool calls — how do I use it as real agent infrastructure?

Treat MCP servers as composable services: expose tools, resources, prompts, and sampling; use remote Streamable HTTP with OAuth resource indicators; nest servers so orchestrators delegate to specialist servers; adopt the 2025-11 Tasks primitive for durable async work.

Journey Context:
In 2024 MCP looked like a USB port for Claude. By 2026 production repos are using it as "microservices for agents": one server can call upstream servers, a dev-scaffolding orchestrator delegates spec/code/test servers, and remote servers replace local stdio. The common mistake is wiring every tool into one monolithic prompt; that breaks cache, exceeds context, and couples failure domains. The 2025-11-25 spec added Tasks, server-side sampling, and structured outputs precisely because teams needed durable, delegable work units, not just RPC. If you still treat MCP as a function-calling shim, you will miss the interoperability layer that OpenAI, Google, and Microsoft are converging on.
