[BUG] Doesn't support MCP 2025-06-18 protocol version #8683
Description
Problem (one or two sentences)
Roo relies heavily on modelcontextprotocol/sdk version 1.12.0, which is outdated. The latest version is 1.20.0, it does not support cases where the MCP server is implemented by 2025-06-18 [2]. This issue was resolved in modelcontextprotocol/sdk versions after 1.13.0.
Currently, when I use Roo with the MCP server implemented on 2025-06-18, I receive a "Server's protocol version is not supported: 2025-06-18" error [4].
