- netx_api/mcp_remote: ops / topology / bizMonitor tools, Bearer auth, per-tool RBAC filtering, ?groups= filter, readOnlyHint and group meta. - Mount the official MCP Streamable HTTP app at /mcp (stateless); AuthAuditMiddleware is pure ASGI and skips /mcp. - Let uvicorn chunk MCP responses; some Windows LSPs rewrite Content-Length replies on */mcp* paths into broken chunked framing. - NETX_MCP_ALLOWED_HOSTS opts into DNS-rebinding checks (off by default so LAN and reverse-proxy hosts work; Bearer is the gate). - Remove the three stdio Python MCP packages; tests moved to /mcp, including real-TCP framing regressions.
