Report #63908

[frontier] Agents polling MCP servers for shared state waste tokens and hit rate limits

Implement MCP sampling where servers request client LLM completions, enabling push-based state synchronization via bidirectional JSON-RPC instead of polling loops

Journey Context:
Traditional tool calling is request-response, forcing agents to poll for state changes. The MCP 2025 spec introduces 'sampling' allowing servers to ask clients to sample LLMs, effectively creating a pub-sub bus. This eliminates polling latency and reduces token usage by pushing state updates only when data changes, treating MCP as a state bus rather than a tool registry.
