Description
Describe the bug
I am using MCPServerSee to establish a SSE connect with the MCP server. Following is the code snippet -
mcp_server = MCPServerSse( name="SSE Python Server", params={ "url": f"{mcp_base_url}/mcp/specs/{chat_id}.yaml/sse", }, ) await mcp_server.connect()This works seamlessly on local but when I run the mcp_server within a docker container along with this app where both the mcp server and this app share the same network, I get an error.
This error doesn't seem like a connection error. Following are the error logs -

P.S. There are no docker setup related issues. Everything is setup correctly.
Debug information
- Agents SDK version: (e.g.
v0.0.16) - Python version (e.g. Python 3.10)
Expected behavior
MCPServerSse should be able to establish the SSE connection even in a docker setup.
