Report #58622

[frontier] Multi-agent systems use ad-hoc message passing with no type safety

Use MCP servers as agent boundaries where each agent exposes capabilities via MCP allowing type-safe discovery and invocation across agent boundaries with JSON-RPC transport

Journey Context:
Agents calling other agents currently use unstructured strings or internal proprietary protocols, leading to interface drift and debugging hell. The fix: treat each agent as an MCP server. Agent A discovers Agent B's capabilities via \`tools/list\`, invokes via \`tools/call\` with strict JSON schemas. This provides type safety, versioning, and standard error handling across process boundaries. Enables 'agent meshes' where capabilities are discovered dynamically rather than hardcoded. Tradeoff: JSON-RPC overhead vs raw function calls. Alternative: gRPC, but MCP provides the semantic layer for LLM-specific concepts \(resources, sampling\).
