MCP Advanced Questions: Expert Challenges
The harder MCP questions our beginner forum routes here — multi-server auth, streaming edge cases, and spec ambiguities.
This thread is for questions that don't have a clean answer yet — spec edge cases, unusual auth topologies, and behavior that varies across client implementations. Beginner questions get routed to our beginner forum instead.

Recurring topics: correct behavior when a resource subscription outlives its session, how clients should de-duplicate identical tool names across aggregated servers, and whether streaming partial tool results is spec-compliant or client-specific.
Answer One, Ask One
If you've resolved one of these in production, post your answer with the client/SDK version you tested against — behavior here shifts between spec revisions.
