Enforce upstream schema validation to pass #134
Description
It's temporary as the upstream schema enforces some requirements on values that we are not complying with, i.e. an sse/streamable-http server type don't have URLs on our side but is expected on the upstream side. It's actually an issue on our side because we made the assumption the MCP endpoints are on the root level of the server endpoint which may not always be the case
