serve-d_0.7.6-windows-x86_64

A successful shutdown request/response and then a request

{"jsonrpc":"2.0","id":6,"method":"exit"}

gave a response

{"error":{"code":-32601,"data":null,"message":"Request method exit not found"},"id":6,"jsonrpc":"2.0"}

This appears to have been fixed in the latest beta version as that version does correctly respond to an exit request.

you specified an "id", which makes this a request and not a notification (thus the "Request method not found" error), which would require a response.

Remove the "id" to make it a notification like the spec says, then serve-d will handle it properly.

Also you are looking at an old spec version there - it's easy to miss updates on it if you e.g. bookmark the pages, so a friendly reminder to check that you are implementing the right spec version right now.
