Research direction
Start at the authorization filters added by #733 and inspect IMcpServerPrimitives, RequestContext, and IAuthorizationPolicyProvider.AllowsCachingPolicies. Compare the proposed Items dictionary and ConditionalWeakTable approaches, then verify that eligible authorization policies are reused across requests without changing authorization behavior.
Written by the indexing model from the issue text.
Description
The authorization filters added by #733 looks up policies for IMcpServerPrimitives every request. This used to also be done by the authorization middleware, but .NET 7 introduced IAuthorizationPolicyProvider.AllowsCachingPolicies which makes it possible to cache at least some authorization policy. We could add an Items dictionary to IMcpServerPrimitives to track the cached policy similar to the Items dictionary #733 adds to the RequestContext<TParams>, or we could use a ConditionalWeakTable<IMcpServerPrimitive, AuthorizationPolicy?>.
