Report #97969

[agent\_craft] MCP client startup is slow and the prompt is bloated because every available resource is loaded into context

List resources and let the model request only the URIs it needs; cache contents, use subscriptions for updates, and evict resources after use.

Journey Context:
MCP resources are application-driven context, not automatic prompt stuffing. A common anti-pattern is to read every resource at connection time and dump them into the system prompt. The protocol provides resources/list and resources/read so the client can expose URIs to the model and let it ask for specific ones. Implement a short-term resource cache keyed by URI and lastModified, subscribe to changes only when necessary, and remove large resource contents from the context once the immediate task is done.
