Otherwise-Rip-9842 · reddit · 2026-08-10
After upgrading a remote MCP server to SDK v2 supporting dual-era protocols (the latest 2026-07-28 and legacy stateless), a developer noticed that the Claude Desktop client still connects using the old handshake (2025-11-25) and lacks support for the new server/discover feature. The poster asks the community if Anthropic plans to update Claude Desktop to support the new MCP spec or if an app update is required.
