Superhuman's MCP now lets Claude and ChatGPT attach files, set reminders and share threads.
Superhuman is a premium email client building a calendar, team comments and AI around its mail core. On 11 November its Mail MCP gained four abilities in Claude, ChatGPT and other AI tools: setting follow-up reminders, sending attachments, using private and team snippets, and sharing threads for team comments. The MCP stays on Business and Enterprise plans, a week after a team admin console reached every plan.
Session ships new app versions and node upgrades while Pro stays on hold.
Session's 2026 started with a funding scare, then community support restored its runway in June. Session Pro reached a beta in app stores in September before its launch was paused in October during talks with an allied privacy ecosystem. Since then the work is infrastructure: lighter Session Node software, an update on Protocol v2, and on November 9 new iOS, Android and Desktop releases with further voluntary node upgrades and progress on a unified client.

Superhuman is making its mail features callable from outside AI assistants rather than only from its own app. Each MCP addition maps an existing Superhuman feature, such as reminders, snippets or shared comments, onto a tool an assistant can use, with sharing gated on the user's confirmation. Keeping the MCP on paid team plans ties it to the admin and usage reporting shipped the week before.
More Superhuman features exposed through the MCP is the likely next step, with calendar and Auto Labels the obvious gaps; the entries do not show whether the MCP will reach lower plans.

With Pro paused, Session is spending its effort on the network and the client codebase: lighter nodes, Protocol v2 with forward secrecy and post-quantum encryption, and one client for all platforms. Monetization waits on the outside talks.
Expect a Protocol v2 alpha or the unified client to be the next visible release; Pro's timing depends on talks the entries do not detail.
