Everything Teams is missing

Built on the official Microsoft Graph API. No scraping. No shadow IT.

MCP ServerUnique

Connect Claude, Cursor, or any AI assistant to your Teams. Read messages, send replies — all via MCP tools.

AI Unread Summaries

Catch up on long threads in seconds. Powered by Claude — highlights blockers and decisions automatically.

Emoji & GIF Picker

Full emoji picker with skin tone support and a built-in GIF search powered by Tenor. No extra setup.

Smart Notifications

Mentions-only mode, keyword alerts, and browser notifications that respect your focus time.

Your data stays in Microsoft

All messages and files are fetched live from Graph API. Teamsly stores nothing on its own servers.

Keyboard-first

Fast navigation, command palette, and shortcuts throughout. Built for developers who live in the terminal.

Self-hostable

Deploy on Vercel, Fly, Render, or your own VM in minutes. Bring your own Azure AD app registration.

File previews & reactions

Inline file preview panel, emoji reactions, threaded replies — all the Teams features you actually use.

Open source · AGPL-3.0

Inspect every line, contribute features, or fork it. Commercial license available for organisations.

MCP Integration

Your AI assistant,
inside Teams.

Teamsly ships a built-in MCP server. Add it to Claude Desktop or Cursor and your AI can list chats, read messages, and send replies — no copy-paste, no switching windows.
