Problem description 问题描述

When trying to connect to a local MCP server that I developed, I get this error message: Run failed: Failed to transform agent message: PluginInvokeError: {"args":{},"error_type":"ConnectError","message":"[Errno 111] Connection refused"}

The MCP server works as intended and is running, I tested it with the MCP inspector. It is deployed with streamable HTTP.

@dotorowoo i got it to work by building a Docker image of my MCP server and adding it as a service to the Dify docker-compose
