Cloudflare MCP servers support new MCP 2026-07-28 Specification
Cloudflare's MCP servers now support the new MCP 2026-07-28 Specification with stateless request handling and compatibility with 2025 Streamable HTTP clients. The /mcp endpoint accepts stateless requests while legacy /sse URLs continue working as aliases, though the deprecated HTTP+SSE transport is no longer served.
Cloudflare's product-specific MCP servers now support the new MCP 2026-07-28 Specification. Each request runs on a fresh stateless server without an MCP protocol session or protocol-specific Durable Object.
The /mcp endpoint also accepts stateless requests from 2025 Streamable HTTP clients. Most clients can reconnect without configuration changes.
Use /mcp for new connections. Historical /sse URLs continue to work as aliases for the same Streamable HTTP handler, but they no longer serve the deprecated HTTP+SSE transport. If a client forces SSE transport, change it to Streamable HTTP or automatic transport detection.
