Client SDK support for notifications/tools/list_changed?

Is your feature request related to a problem? Please describe.

This is more of a question vs. a feature request, so please let me know if I should direct elsewhere.

I've implemented a server that supports the notifications/tools/list_changed notification. But I noticed the TypeScript client SDK doesn't handle that notification natively. Are individual MCP clients expected to set their own notification handler for that message, updating the list of tools for that particular session accordingly?

Describe the solution you'd like

It might be nice for the client SDK to have a helper method like the Java SDK does. I added this in a fork while we work on our server, but didn't want to raise a PR before getting feedback on how you expect the client to handle this situation.

Fantastic project! Looking forward to working with MCP more.

I'm facing a similar issue. Raising the tools list change notification (and configured the capabilities to listChanged: true) but it does not seem to show up in the server notifications in the inspector.

        {
            capabilities: {
                tools: {
                    listChanged: true,
                },
            },
        }
