[frontier] MCP is just another tool-calling protocol — how to get real architectural leverage from Model Context Protocol?

Use MCP's full primitive set beyond Tools: Resources for contextual data exposure \(files, schemas, API responses\), Prompts for parameterized reusable prompt templates, and Sampling for server-initiated LLM requests. Compose multiple MCP servers as a universal integration layer any agent can plug into.

Journey Context:
Most early MCP adopters only use the Tools capability, treating it as a slightly-better-standardized function-calling interface. But MCP defines four primitives and the other three unlock different value: Resources let servers expose contextual data that agents discover and read on demand — think database schemas, file contents, or API responses surfaced without explicit tool calls. Prompts provide parameterized, reusable prompt templates that encode domain expertise. Sampling lets servers request LLM completions from the client, enabling server-side agentic behavior where the integration itself can reason. The emerging architectural pattern is composing multiple MCP servers — each wrapping a different system — into a unified context and capability layer. This replaces bespoke per-agent integration code with a standard protocol. Any new agent just connects to the MCP layer and gets access to everything. The tradeoff: MCP server composition requires careful capability namespacing to avoid conflicts, and Sampling introduces latency and cost from nested LLM calls.
