FileCache is not working

[bangnokia]

When using FileCache for the server, it keep saying Client not initialized when get list tools. (I'm using MCP inspector)
I think because of it using json_encode, json_decode instead of serizlize and unserialize so it can not get the right object from the cache (array returned right now)

Hi @bangnokia, thanks for clocking this one!

You were absolutely correct in your diagnosis. This fix has been committed and will be included in the next release. Cheers 🍻
