Report #69088
[frontier] Agents polling for updates causing high latency and resource waste
Implement MCP Resource subscriptions to stream updates \(logs, events, partial results\) between agents using server-sent events or streaming JSON-RPC instead of synchronous polling
Journey Context:
Standard tool-calling assumes synchronous request-response patterns, forcing agents to poll for long-running operation results. This creates unnecessary latency and token waste. The MCP specification supports resource subscriptions where servers push updates to clients. By modeling inter-agent communication as resource streams rather than tool calls, agents can react to events in real-time \(e.g., build logs, file changes, other agent outputs\) without tight coupling. This enables reactive workflows where agents coordinate through event streams rather than blocking calls.
