How DaySurface compares
Most Gmail MCPs hand your agent raw API calls and a wall of JSON. DaySurface is a Gmail product: an interactive inbox you can drive from inside the chat, open source and yours to host.
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.
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.
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.
