Permanent VPS MCP registration is reserved for servers requiring local access or Bearer auth (sequential-thinking, vault-mcp, graphiti-mcp, omnigraph, openspace-mcp, xint, serena). Public no-auth HTTPS endpoints (excalidraw, notebooklm-mcp, researchclaw, hostinger-admin) moved to Claude Desktop Custom Connectors — zero VPS context cost when disabled, dynamic per-session. xint cannot be Desktop-bridged due to Bearer auth incompatibility with Desktop’s OAuth 2.0 DCR requirement.
