cannot use custom cert when connecting to server with MCPServerSse

[Arif-Karim]

Hello team,

Trying to connect to the server like this:

async with MCPServerSse(
                name="Sample Server",
                params={
                    "url": self.server_url,
                    "timeout": 60,
                }
            ) as mcp_server:
                logger.info(json.dumps({
                    "content": "MCP server connection established successfully",
                    "metadata": {
                        "server_name": "Sample Server",
                        "success": True
                    }
                }))
                mcp_agent = Agent(
                    name="MCP Agent",
                    instructions="You use the tools provided to answer the question",
                    model=self.model,
                    model_settings=ModelSettings(extra_headers= AzureOpenAIConnector.populate_extra_headers()),
                    mcp_servers=[mcp_server],
                )

However when i try and connect to the server I get self signed certificate error because the request is using our company's certs. I was able to get around the solution by setting

os.environ["REQUESTS_CA_BUNDLE"] = "/etc/ssl/certs/ca-certificates.crt"
os.environ["SSL_CERT_FILE"] = "/etc/ssl/certs/ca-certificates.crt"

before the execution and then reverting the cert back after the code execution. But my manager does not like the fact that I am setting the cert globally even if its just for the execution.

I have looked at the docs and cant seem to find a parameter to pass in a SSL context when using MCPServerSse.

Could you please suggest a way around this and if possible include a for us to pass in a SSL context in the future.
