Report #79783
[frontier] Agents waste tokens polling MCP resources for state changes, causing latency and rate limit exhaustion
Implement MCP Resource subscriptions to receive real-time push notifications when external state changes, eliminating polling loops
Journey Context:
Initial MCP integrations used synchronous resource/read operations in polling loops, creating 1-3 second latencies and hitting rate limits. The MCP spec's 'subscriptions' feature allows clients to subscribe to resource URIs; servers push notifications via \`notifications/resources/updated\` when values change. This enables reactive agent architectures where tools trigger immediately on external events \(database changes, file updates\), critical for real-time automation.
