[BUG] Resource autocomplete cannot dynamically change or update.

[SamPeng87]

Bug Description

I developed an MCP server that exposes a list of resources. I also experimentally added a tool to dynamically add to this resource list. When starting Claude code, after the first @ or actively listing resources, the @ shows the resources exposed by MCP. However, after dynamically adding resources, listing resources correctly returns the new resource list. The @ autocomplete, however, does not update and cannot get the new resources. I tried sending notifications/resources/list_changed, but Claude code did not respond at all.

Steps to Reproduce

1. start claude code。can see resource list and @ autocomplete work,
2. do something add resource and send notifications/resources/list_changed, prompt list resources can list that new resource, but @ no any changed,I can see mcp server not receive anything.
3. restart claude code,can see new resource list and @ is work fine

Expected Behavior

1. @ can update by resource list changed
2. receive notifications/resources/list_changed with mcp,and send resource/list,that is mcp rfc defined

Actual Behavior

1. @ can't update with resource list
2. not send resource/list after notifications/resources/list_changed

This is not about resource templates, is that correct? I believe that would require the Completion endpoint too, and I'm unsure if Claude Code supports that yet either. So perhaps unrelated: closed issue #3122 for resource templates. I'm unsure if it was actually implemented. 🤔

It would be quite helpful if everything related to resources worked correctly in Claude Code -- change notifications for "static" resources and dynamic resources for LLM searching via completion.
