Support Resource Subscriptions
Is your feature request related to a problem? Please describe.
I want to make sure that my resource subscriptions are working properly. Because so many clients don't support resource subscriptions (do any popular hosts?), the Inspector is a good first spot to start testing this capability.
Describe the solution you'd like
Perhaps there's a button on each resource to trigger a subscription with the resources/subscribe method on that resource and then it keeps the displayed content for that resource up-to-date.
Describe alternatives you've considered
Manually fetching in the UI.
Looks like this is already supported as of https://github.com/modelcontextprotocol/inspector/commit/747c0154c51dfc42f001c3f14cdd9484dcdd8d29, but many servers don't advertise this capability. I found FastMCP hard-codes the inability to subscribe to resources, so the button doesn't show.
Resource subscriptions are already supported (one of the first features I added). Server has to support subscriptions, try the Everything server. I also added support there at the same time.
