Question: How to pass environment variable from MCP client to MCP server (sse_client)

[injusticescorpio]

For stdio_client I have seen an option

python-sdk/src/mcp/client/stdio/__init__.py

Line 116 in c2ca8e0

env=(

but not for sse_client
Is there any way to send some environment variables from mcp-client to mcp-server that can change the behaviour of mcp server depending up on the env.

Try putting variables in HTTP headers

@kagezhao Do you know how to get the header in the server?
