# Notion MCP supports MCP protocol version 2026-07-28

By Steven Van · 2026-08-03

The Notion MCP Streamable HTTP endpoint at https://mcp.notion.com/mcp now supports MCP protocol version 2026-07-28.

The [Notion](<https://creatorstoolbox.com/tools/notion>) MCP server's Streamable HTTP endpoint, at mcp.notion.com/mcp, now supports MCP protocol version 2026-07-28. Existing MCP clients that still negotiate the earlier 2025-era protocol on that same endpoint keep working as before, so no client-side changes are needed to stay connected.
