- Fix DEFAULT_PROTOCOL_VERSION typo: 2025-11-05 → 2024-11-05 (non-existent version caused 400s on servers that validate it) - Parse SSE-framed response bodies (data: ...) returned by streamable HTTP servers per MCP spec - Capture mcp-session-id from initialize response and send it on all subsequent requests - Include response body in HTTP notification error messages for easier debugging - Add debug logging for raw HTTP MCP responses Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

@everettjf I tried using streaming http mcp tools and they didnt work. I started fixing the implementation in the codebase, but quickly ran into more issues. So I replaced the implementation with the library one. MCP is not simple to implement, so many tricky little cases. Now it works great with my http servers (fast mcp python servers) |
