Works fine with domain-only URLs (no subpaths).\n\n### Reproduction Steps\n1. Deploy an SSE MCP server with subpath (e.g. /mcp/a/sse)\n2. Connect using Cline or Cherry Studio client\n3. Observe \"could not find session\" 404 error\n\n### Expected Behavior\nClient should be able to connect to SSE MCP service with subpaths\n\n### Environment Information\n- MCP Version: [please specify]\n- OS: [please specify]","author":{"url":"https://github.com/gzchen008","@type":"Person","name":"gzchen008"},"datePublished":"2025-04-11T09:10:38.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/490/python-sdk/issues/490"}
