+An MCP server portal centralizes multiple [Model Context Protocol (MCP) servers](https://www.cloudflare.com/learning/ai/what-is-model-context-protocol-mcp/) and their tools onto a single HTTP endpoint. Key benefits include:
 
 - **Streamlined access to multiple MCP servers**: MCP server portals support both unauthenticated MCP servers (such as the [Cloudflare Documentation MCP server](https://github.com/cloudflare/mcp-server-cloudflare/tree/main/apps/docs-vectorize)) as well as MCP servers secured using any [third-party or custom OAuth provider](/agents/model-context-protocol/authorization/). Users log in to the portal through Cloudflare Access and are prompted to authenticate separately to each server that requires OAuth.
