Superhuman pushes calendar onto mobile and opens the inbox to AI agents via MCP.
Superhuman is a speed-focused email client now building out two fronts at once: calendar features across mobile (Android calendar, multi-day iOS views, share-availability) and an agentic layer that lets external AI tools drive the inbox through MCP and a Codex plugin. The release cadence is high and split between mobile parity and AI access.
Amid a wall of MarTech-migration SEO, Netcore shipped a real move: CPaaS MCP servers across four channels.
Netcore Cloud's feed is mostly content marketing — a heavy MarTech-migration series and buyer-guide SEO — but it carries one genuine product release: CPaaS MCP servers exposing email, SMS, WhatsApp, and RCS through 64 tools driven by plain-English prompts. The signal-to-noise is low, but the MCP launch is a real directional move.

The release cadence is high and split between mobile parity and AI access.
Superhuman is turning its mail client into something AI agents can operate, with search, draft, schedule, send, and triage from Claude, ChatGPT, or Codex, while filling mobile gaps to keep parity with desktop. The bet is that being the most automatable inbox matters as much as being the fastest one.
The next likely move is more MCP-driven capability and continued mobile calendar buildout, extending the Codex/Claude/ChatGPT integration and the new Android and iPad calendar surfaces.

The signal-to-noise is low, but the MCP launch is a real directional move.
The product direction visible here is AI-interoperability: letting assistants drive Netcore's messaging channels through MCP rather than hand-written API calls. The surrounding migration content suggests a parallel go-to-market push to win platform-switching enterprises.
Expect Netcore to extend the MCP tool surface across more of its engagement stack and to keep pairing it with migration-focused marketing aimed at displacing incumbent ESPs.
