Platform Chat + MCP Server breaks after switching prompt

When you have a chat on the platform website with an MCP Server configured that has a path as tools, if you change the selected prompt it breaks MCP server url appending .

In addition to this there is no way to edit the server URL, so you have do delete and recreate it from scratch every time.

I hope this helps!
