[frontier] Agent tools use ad-hoc interfaces making composition brittle; integrating new tools requires custom code per integration

Adopt Model Context Protocol \(MCP\) as the fundamental ABI: expose all capabilities via MCP servers with strict JSON Schema contracts, consume via MCP clients, enabling any agent to use any tool or delegate to another agent through the same typed interface without custom glue code.

Journey Context:
Early systems hardcoded tool integrations, creating N×M complexity. MCP standardizes transport and schema, allowing tools to be developed independently and composed dynamically. This creates an 'ABI for agents' where the boundary between tool and agent blurs—an agent can expose itself as an MCP server to other agents, enabling recursive hierarchies without bespoke integration.
