Report #55707

[frontier] Agents work with stale data because they poll external systems rather than receiving live updates

Use MCP's resource subscription capability to push live data updates \(database changes, logs, events\) directly into the agent's working memory without polling loops

Journey Context:
Current agents typically use tools to fetch data when they think they need it, leading to stale context or excessive polling. The emerging pattern leverages MCP's resource system \(distinct from tools\) which supports subscriptions. The agent subscribes to resources \(e.g., a database table, a log stream, a file\) and the MCP server pushes updates via notifications. The agent's context manager updates its working memory incrementally, enabling reactive agent behavior without explicit fetch calls. This turns agents into event-driven systems.
