Cloudflare MCP servers adopt the MCP 2026-07-28 specification
Cloudflare updated its remote MCP servers on 28 July 2026 to the MCP 2026-07-28 specification and stateless Streamable HTTP model at /mcp, while retaining /sse aliases for compatibility.
Previous state
Cloudflare's remote MCP servers used the earlier MCP transport and session model.
Current state
Cloudflare remote MCP servers use the MCP 2026-07-28 specification with stateless Streamable HTTP on the /mcp endpoint; /sse aliases remain available for compatibility.
Affected users
Who needs to care
Clients and agents integrating with Cloudflare's remote MCP servers and relying on transport, endpoint or session behaviour.
Required response
What to do
Validate MCP clients against the stateless Streamable HTTP behaviour and prefer /mcp for current integrations while preserving compatibility handling where /sse is still used.
Evidence boundary
What the source does not prove
Cloudflare states that /sse aliases remain available. This event must not be represented as an immediate removal of the older HTTP+SSE path.
