How to Connect to MCP with Langflow using StreamableHTTP

This article explains how to achieve an MCP (Model Context Protocol) connection using the StreamableHTTP protocol in Langflow version 1.5.1.
Although the current version does not directly support this, a connection can be established via mcp-proxy.

Configuration Example

{
  "mcpServers": {
    "mcp_name": {
      "command": "uvx",
      "args": ["mcp-proxy", "--transport", "streamablehttp", "http://address/mcp"]
    }
  }
}

Note

Langflow 1.5.1 supports SSE connections, but compatibility with the MCP server-side implementation can be tricky. If you experience instability with SSE, you might consider using StreamableHTTP as an alternative.
