DaySurface vs Google Workspace MCP
Gmail done deeply vs. Workspace done broadly.
Google Workspace MCP covers a huge surface - Gmail, Calendar, Drive and Docs - as headless tools you run yourself. It's a great fit when you need the whole suite. DaySurface goes the other way: deep on Gmail with an interactive in-chat composer and ranked-inbox dashboard, a minimal single Gmail scope, and the same tools exposed over CLI and HTTP as well as MCP.

|---|---|---|
| Interactive in-chat UI (MCP Apps) Composer + ranked-inbox dashboard rendered inside the chat client. | ✓ | – JSON only |
| Built-in inbox triage & ranking An importance-ranked inbox out of the box, not just raw search. | ✓ | – raw search |
| One codebase → CLI + MCP + HTTP Identical tools across every interface, no duplicated logic. | ✓ | ~ MCP only |
| Zero-install (remote streamable HTTP) Connect by pasting a URL - nothing to install locally. | ✓ | – self-run |
| Open source & self-hostable Run the full server on your own infrastructure. | ✓ | ✓ |
| Minimal scope + encrypted tokens A single Gmail scope with tokens encrypted at rest. | ✓ | ~ broad scopes |
Comparison reflects publicly documented capabilities as of June 2026. The MCP ecosystem moves fast - if something here is out of date, open an issue and we'll fix it.

01 Interactive UI, not just JSON
DaySurface renders MCP Apps - sandboxed UI that lives inside the chat. Review and edit a draft in a real composer, then triage a ranked inbox in an embedded dashboard, all without leaving your agent. The inbox ranking and triage flow exist because the interactive surface makes them useful; other Gmail MCPs return raw search results and stop there.
02 One codebase, three transports
Every tool is a pure function in a shared registry, exposed identically over a CLI, an MCP server, and a plain HTTP API. Build once and call it from your shell, any MCP client, or a script - behavior never drifts between interfaces. Most Gmail MCPs are single-transport: stdio-only, or a hosted endpoint you can't run locally.
03 Open source and self-hostable
The whole server is open source and ships with a Dockerfile and deploy config, so you can run it on your own infrastructure with your own OAuth credentials and encrypted token storage. Aggregator gateways route your mail through a proprietary service you don't control.
