[frontier] Agents cannot interoperate due to custom tool definitions and brittle API contracts

Adopt MCP \(Model Context Protocol\) as the universal interface layer—use it not just for tool-calling but as the standard interface between agents, exposing capabilities, resources, and prompts via MCP servers

Journey Context:
The pattern moves beyond using MCP merely for tool-calling to treating it as the inter-agent glue. Instead of building custom REST APIs between agents, you implement MCP servers that expose your agent's capabilities. This creates a plug-and-play ecosystem where agents can discover and use each other's tools dynamically via the standardized protocol. Tradeoff: adds ~50ms latency and requires maintaining MCP server infrastructure, but eliminates N×M integration hell. This is emerging in Q1 2025 as the standard for agent interoperability, moving beyond the initial tool-use hype into full protocol adoption.
