What is Superhuman?
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.
What is Misskey?
Misskey 2026.11 ships: a leaner start script, and Node.js 22 no longer boots.
Misskey 2026.11.0 is out after an alpha, two betas and a release candidate in a week. The new start script stops extra processes from staying resident, saving about 50MB per server on the official Docker image, which uses it automatically. Node.js v22 support ends, the minimum is now 24.22.3 or 26.13.1, and NODE_OPTIONS paths now resolve from the repository root. Smaller changes include better display of Mastodon quotes and an autoplay setting for URL previews.
Superhuman vs Misskey: editorial side-by-side
Superhuman
5.0COMMS
Superhuman's MCP now lets Claude and ChatGPT attach files, set reminders and share threads.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Misskey
5.0COMMS
Misskey 2026.11 ships: a leaner start script, and Node.js 22 no longer boots.
◆ Current state
Misskey 2026.11.0 is out after an alpha, two betas and a release candidate in a week. The new start script stops extra processes from staying resident, saving about 50MB per server on the official Docker image, which uses it automatically. Node.js v22 support ends, the minimum is now 24.22.3 or 26.13.1, and NODE_OPTIONS paths now resolve from the repository root. Smaller changes include better display of Mastodon quotes and an autoplay setting for URL previews.
◆ Where it's heading
Misskey's last two cycles are about making servers cheaper and safer to run: tighter Sentry data-collection defaults in 2026.10, lower memory and newer Node versions in 2026.11. Each one carries a breaking requirement that admins must check before upgrading.
◆ Prediction
Expect 2026.11.x patch releases for upgrade problems, especially around custom NODE_OPTIONS and systemd units. The entries do not show what the next feature cycle will target.
