Pass the middlware auth user id into the Tool

[nadar]

I have installed the dev-main because of middlware function, because we need auth in order to change the tools response.

Using StreamableHttpServerTransport with PSR-7 middleware that sets:

class AuthMiddleware
{
    public function __invoke(ServerRequestInterface $request, callable $next)
    {
        // here how can i access this user_id inside a tool?
        $request = $request->withAttribute('user_id', $mySuperDuperUserId);

        $result = $next($request);
        
        return match (true) {
            $result instanceof PromiseInterface => $result->then(fn($response) => $this->handle($response)),
            $result instanceof ResponseInterface => $this->handle($result),
            default => $result
        };
    }

What’s the supported approach to read this user_id inside a Tool handler?

Constraints

• (a) Constructor/DI injection won’t work because the PSR-7 request is per-request and can’t be bound at configuration time.
• (b) Adding a ServerRequestInterface parameter to the handler also won’t work because it becomes part of the Tool’s schema (clients would have to pass it).
