DaySurface vs Composio Gmail
A Gmail product, not a Gmail endpoint in a 500-app gateway.
Composio's strength is breadth: one managed endpoint and hosted OAuth across hundreds of SaaS apps, with Gmail exposed as a generic search / read / draft / send toolkit. DaySurface trades breadth for depth on email - an interactive composer and ranked-inbox dashboard rendered in the chat - and it's open source, so you self-host with your own credentials instead of routing mail through a proprietary gateway.

| One codebase → CLI + MCP + HTTP Identical tools across every interface, no duplicated logic. | ✓ | – hosted endpoint |
| Zero-install (remote streamable HTTP) Connect by pasting a URL - nothing to install locally. | ✓ | ✓ |
| Open source & self-hostable Run the full server on your own infrastructure. | ✓ | – proprietary |
| Minimal scope + encrypted tokens A single Gmail scope with tokens encrypted at rest. | ✓ | ✓ managed |

Choose DaySurface if…
email is the job: you want an interactive in-chat inbox, full control of your own deployment, and the ability to run the same tools over CLI and HTTP.
Choose Composio Gmail if…
you need one managed endpoint spanning many SaaS apps and you don't want to run any infrastructure yourself.

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.
