执行：uv run oceanbase_mcp_server --transport sse --host 0.0.0.0 --port 8000
看样子一切正常：
2025-06-16 13:30:23,524 - oceanbase_mcp_server - INFO - Starting OceanBase MCP server with sse mode…
INFO: Started server process [15309]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
但是我用客户端，或者直接访问http://ip:8000都会404
求助该怎么排查
