Report #71722

[frontier] Agent context becomes stale with polling-based tool calls causing latency and inaccurate state

Implement MCP Resource subscriptions using the 2025-03-26 spec to receive reactive push updates for live state \(databases, files, APIs\)

Journey Context:
Traditional tools poll HTTP endpoints creating delays and race conditions. The 2025 MCP spec adds resource subscriptions enabling pub/sub patterns where servers push updates to agents. Tradeoff: requires managing subscription lifecycle and handling reconnection, but eliminates polling overhead and ensures real-time context for trading, monitoring, or collaborative editing agents.
