Sauna reads Mercury and turns it into answers: it pulls the numbers, builds the report, and flags what moved — and can run the recurring summary on a timer.
Sauna + Mercury
Sauna's Mercury integration turns your numbers into answers: it pulls revenue, orders, or balances into a chart and a one-pager, reconciles and flags what doesn't match, and runs the recurring report — no SQL, no dashboard-building.

Connect
Connect it with an API key from the library, or ask Sauna in chat and paste the key into the form it opens. Add more than one account if you need to.
Mercury is one of thousands of apps in Sauna's library. Anything not in the library, you add yourself with an API key or an MCP server — right from chat.
In context
Once Mercury is connected, Sauna reads and acts on it from plain language — across the web app, Slack, email, iMessage, and Superhuman — and waits for your approval before it writes anything.

Yes. Unlike most tools, Sauna lets you link as many Mercury accounts as you need — each with its own reconnect and remove controls.
Sauna reads only what you connect, and acts only after you approve. Your workspace and its memory are yours, not training data.
