Expose request context access in McpServerExchange implementations

[gakkiyomi]

How can I retrieve information carried in the request (such as headers and client IP) from McpSyncServerExchange or McpAsyncServerExchange? I'm using HttpServletSseServerTransportProvider and need to log client IPs calling MCP services while monitoring traffic. Currently I modified the 0.10.0 SDK source as follows: Made McpAsyncServerExchange.getSession() public, McpServerSession.getTransport() public, and HttpServletMcpSessionTransport.getAsyncContext() public to implement:

/**
 * Retrieves client IP from exchange
 * @param exchange {@link McpSyncServerExchange}
 * @return IP address
 */
private String getClientIp(McpSyncServerExchange exchange) {
    var session = exchange.getExchange().getSession();
    var transport = (HttpServletMcpSessionTransport) session.getTransport();
    var context = transport.getAsyncContext();
    var request = (HttpServletRequest) context.getRequest();
    return NetUtils.getClientIpAddress(request);
}

But this approach feels hacky ("Monkey patch"). Are there plans to expose request context access during server-side processing in future versions?

I have similar needs to you. Currently, my implementation method is to use a filter to obtain request information before routing the request.

I think this will be needed as more and more people are creating MCP server over their existing REST endpoints.

This feature has been implemented, please use McpTransportContext
