Description

I was testing the snippets in the repo corresponding to the URL mode elicitation. When I run connect-service tool the server seems to be raising UrlElicitationRequiredError. However on the client I dont see this being translated into the McpError exception and instead just seeing as a result error.

Example Code

Using the standard snippets. 

cd examples/snippets
# Server
uv run server elicitation sse
# Client
uv run elicitation-client
