Connect your data to dots
Add Sequel once in ChatGPT and your dot can answer data questions on its own, day and night.
What dots can do with Sequel
No separate setup for the dot
There is no "connect apps to your dot" step for custom connectors. Anything installed under Settings → Plugins, including a developer-mode MCP connector, is available to the dot from its first message, and the same plugin serves ChatGPT, Codex and your dots.
It keeps working after you leave
A dot runs on its own cloud computer and pursues goals in the background, so it can use Sequel inside a scheduled task: the Monday morning numbers, a daily spend-versus-revenue check, an alert when signups fall off their trend.
Read-only by default, on both sides
Sequel marks its tools read-only and shows each query before it runs. Set the Sequel plugin to "Allow read-only tools" and reads run freely while anything that changes something has to ask, so a dot acting on its own initiative cannot touch your data.
Everything you can ask dots about your data.
Ask in plain English. Sequel turns it into a query, runs it read-only, and dots hands back the answer. No SQL, no dashboards, no CSV exports.

Setup
Add Sequel to dots
Drop the Sequel MCP server into dots, then ask it anything about your connected data. Sequel is read-only by default and shows each query before it runs.
ChatGPT → Settings → Connectors (developer mode)
Server URL: https://api.sequel.sh/mcp Authentication: OAuth, sign in with Sequel when ChatGPT asks Then: Settings → Plugins → Sequel → Allow read-only tools
Install
Install Sequel MCP in dots
Pick your app and Sequel installs itself: a one-click link where the client supports it, that client’s own few steps where it doesn’t. Every route signs in with your Sequel account over OAuth, so there is no API key to copy and nothing to keep in sync.
Already have an MCP client?
https://api.sequel.sh/mcp
Add it as a remote (streamable HTTP) server and sign in when prompted. Skills come with it; nothing else to install. Manual setup per client

- 1In ChatGPT, open Settings and turn on Developer mode. It needs a paid plan, and in a workspace an admin may have to grant it.
- 2Add a connector, name it Sequel, paste the URL and leave authentication on OAuth. Sign in to Sequel in the window that opens.
- 3Under Settings → Plugins, set Sequel to “Allow read-only tools”.
- 4Your dot has it already. Ask it “which apps can you use right now?” to confirm.

Frequently asked questions
Can an OpenAI dot use a custom MCP server?
Yes. A connector added through developer mode in ChatGPT is available to your dot with no extra step, because a dot has access to the plugins installed on your ChatGPT account. The same connector works in a normal chat, in Codex, and inside the dot's scheduled tasks.
How do I add Sequel to my dot?
In ChatGPT, turn on developer mode in Settings, add a new connector named Sequel with the URL https://api.sequel.sh/mcp, choose OAuth, and sign in to Sequel in the window that opens. Then ask your dot "which apps can you use right now?" Sequel should be one of them.
What do I need to use dots with Sequel?
A dot (included with ChatGPT Pro and Business Premium in eligible markets), developer mode for custom connectors, which is paid-plan only and may need a workspace admin's permission, and a Sequel account with at least one source connected.
Which permission level should I give the Sequel plugin?
"Allow read-only tools" is the right default: Sequel flags each tool, so reads run without interruption while anything that changes something asks first. Note that an explicit request in the conversation counts as your approval, so the level protects you from the dot acting unprompted only.
Which data sources can a dot query through Sequel?
Any source you have connected in Sequel: PostgreSQL, MySQL, ClickHouse, BigQuery, Snowflake, Google Analytics, Search Console, Google Ads, Meta Ads, HubSpot, Stripe, and more. The dot can only reach the connections your organization has set up.
