The integration of the Model Context Protocol (MCP)<\/strong> servers within Open WebUI significantly extends its functionality, by allowing access to external capabilities. Open WebUI both leverage native support for MCP server offering the HTTP streamable format, and usage of the mcpo (MCP-to-OpenAPI proxy server)<\/a><\/strong> for broader compatibility.<\/p>\n\n\n\n

This article explains how to configure Open WebUI’s native support for remove MCP servers offering HTTP streamable capabilities. For a guide on how to configure MCPO<\/a> to leverage all kinds of MCP servers: local via sdio, or remote via SSE (Server-Sent Events), or Streamable HTTP, please refer to this article<\/a>.<\/p>\n\n\n\n

What is MCP?<\/h3>\n\n\n\n

MCP<\/strong> is an open standard that functions as a universal communication bridge, connecting LLMs to external tools and data sources. This protocol enables AI assistants to access real-time information and perform tasks on a variety of different areas.<\/p>\n\n\n\n

MCP servers communicate with clients (the LLMs) using three primary channels: stdio<\/strong><\/code> (standard input\/output), SSE<\/strong> (Server-Sent Events), or Streamable HTTP<\/strong>.<\/p>\n\n\n\n

Connect to MCP via HTTP Streaming<\/h3>\n\n\n\n

In v0.6.31<\/a> Open WebUI added MCP (streamable HTTP) server support, alongside existing OpenAPI server integration. This allows to connect directly to an MCP server that exposes its functionality over a streaming HTTP endpoint. It supports Bearer token, session and OAuth for authentication, if necessary (doc page<\/a>, but very basic so far<\/em>).<\/p>\n\n\n\n

To find MCP servers, the “Remote MCP Servers” page of Awesome MCP Servers<\/a> is a good starting point. Looking at all the servers with http<\/code> support, let’s user the one from CoinGecko<\/a>.<\/p>\n\n\n\n

Once logged in Open WebUI:<\/p>\n\n\n\n

    \n
  1. Navigate to Admin Panel<\/strong> -> Settings<\/strong> -> External Tools<\/strong>.<\/li>\n\n\n\n
  2. Click “+<\/strong>“ (Add Connection)<\/em>.<\/li>\n\n\n\n
  3. Set the Type<\/strong> to MCP Streamable HTTP<\/strong>.<\/li>\n\n\n\n
  4. Set the URL<\/strong> to https:\/\/mcp.api.coingecko.com\/mcp<\/code><\/li>\n\n\n\n
  5. Set Auth<\/strong> to None<\/strong>.<\/li>\n\n\n\n
  6. Set ID<\/strong> to coingecko_mcp_http<\/code>.\n
