Build a Routine with ChatGPT via Routinery MCP: Setup and First Steps (2026)

Last updated: 2026-09-10

Turn on Developer Mode under ChatGPT's Security and login settings, add Routinery as a custom connector using the public endpoint https://mcp.routinery.app/mcp, then enable it inside a chat before you ask for a routine. ChatGPT requires a paid plan for this. Routinery's side of the connection is free either way.

Most routine apps assume you're willing to open them, tap through a few screens, and set things up by hand. Chatting your way to a finished routine is a different habit to build, and if-then planning research offers a reason it might stick better: a meta-analysis of 94 studies found that turning a goal into a specific plan moves follow-through by an average effect size of d = 0.65, a mid-to-large effect in behavior research. Asking ChatGPT to draft that plan in the middle of a conversation, rather than opening a separate app to do it, is one way to lower the friction between deciding and doing.

What the connection enables: seven things ChatGPT can do

Routinery's MCP page documents what changes once the connection is live, and it's worth reading the list literally. ChatGPT can view a routine and read back its habits, durations, and total length. It can draft a new one from a plain description, attaching timers and repeat days as it goes. It can edit a single step, such as shortening meditation to five minutes, and it can duplicate a routine onto a different day. Two more use cases leave Routinery entirely: putting a routine on Google Calendar as a recurring event, and organizing routines into a Notion page. Both work because ChatGPT already holds its own separate connection to your calendar or your Notion workspace, and Routinery's MCP server only supplies the routine data for it to write elsewhere. A seventh use case reads your history back to you, describing completion rates, streaks, and the days you tend to skip as a pattern instead of a spreadsheet.

None of that runs unsupervised. Routinery's own MCP page states plainly that it requires explicit confirmation before creating, duplicating, or editing anything, and asks you to review the exact action before it saves. ChatGPT proposes the change in the chat, and nothing happens to your routines until you approve it there.

Turn on Developer Mode first: the requirement that's specific to ChatGPT

This is the step that trips up anyone coming from Claude, where Routinery's own FAQ confirms the connection works on every plan including the free tier. ChatGPT is different. Routinery's own FAQ says it directly. Connecting requires a paid ChatGPT plan, meaning Plus, Pro, Business, or Enterprise, with Developer Mode switched on. A free ChatGPT account can't add this connector at all, regardless of anything on Routinery's side.

OpenAI's own developer documentation, not Routinery's, lays out where that toggle lives. It's a 3-step path: open Settings, select Security and login, then turn on Developer Mode. That switch makes the custom connector option appear in the first place, but it doesn't add Routinery on its own. The next section covers the part that does.

Connect Routinery's MCP server to ChatGPT: the steps

Once Developer Mode is on, adding Routinery still takes a separate 4-step form, not a single toggle.

1. Go to ChatGPT's Plugins screen and select the plus button to start a new connector.
2. Enter a name and description you'll recognize later, such as "Routinery."
3. Under Connection, choose the public endpoint option, not a tunnel.
4. Paste in Routinery's server address: https://mcp.routinery.app/mcp

Saving the connector doesn't turn it on inside a chat by itself. Open a new conversation, find Connectors there, and switch Routinery on before you ask about your routines. Skip that step and ChatGPT answers as though it has never heard of the app, which reads exactly like a broken connection and isn't one. The first time you use it, Routinery asks you to sign in and authorize the connection with your Routinery account, and that sign-in step is what actually links your data. The server address alone isn't enough.

What to try first: a read, then a small edit

Start with a read before you ask for anything to be built. Ask ChatGPT to show you tomorrow's routine so you can see what a routine object looks like coming back through the connection before you trust it with an edit. Then try a small change, like moving a habit's duration by a few minutes. That's where the confirmation step becomes visible. ChatGPT proposes the exact change and waits for your approval before saving it. Once that feels familiar, ask it to draft something new from scratch, for example a wind-down routine with three habits and a total length you specify.

If you're deciding whether a chat-based connector like this is worth setting up compared to a dedicated planner you already use, our review of Notion as a habit and routine tool covers that trade-off from the other direction. And if you want to see how Routinery's MCP support stacks up against other habit and routine apps that have shipped their own connectors, the roundup of AI-connected routine apps puts them side by side.

If it doesn't work: two ChatGPT-side snags

Developer Mode is on, but the connector option isn't there. Double check the plan on the account you're using. Routinery's requirement isn't a suggestion. Free ChatGPT accounts don't get Developer Mode regardless of what else is configured, so switching accounts or upgrading fixes it, not retrying the same steps.

The connector saves, but ChatGPT still says it can't see your routines. This is usually the enable-inside-the-chat step, not a broken server address. Adding a connector and turning it on inside a specific conversation are two different actions, and the second one resets for each new chat. Open Connectors in the chat you're using and confirm Routinery is switched on there before asking again.

Frequently asked questions: ChatGPT and Routinery MCP

How do I build a routine with ChatGPT using Routinery MCP?

Turn on Developer Mode in ChatGPT's Security and login settings, then add a custom connector using Routinery's public endpoint, https://mcp.routinery.app/mcp. Once it's added, open a new chat, enable Routinery under Connectors, and sign in with your Routinery account when it asks. From there, describing a routine in plain language, such as a ten-minute wind-down with three habits, is enough for ChatGPT to draft it, and it will show you the exact steps before saving anything.

Does connecting Routinery to ChatGPT cost anything?

Not on Routinery's side. Routinery's MCP page states the connection is free for every user regardless of subscription status. The cost sits with ChatGPT instead. Developer Mode and custom connectors require a paid plan, specifically Plus, Pro, Business, or Enterprise, so a free ChatGPT account can't use this feature no matter what Routinery plan you're on.

Why does ChatGPT need a paid plan when Claude doesn't?

Routinery's own FAQ draws this distinction directly, stating that Claude works on every plan including the free tier while ChatGPT requires a paid one with Developer Mode enabled. That's a restriction OpenAI sets on its side of the connection, not something Routinery chose, and it applies the same way to any custom connector, not just this one.

Can ChatGPT put my Routinery routines on Google Calendar?

Yes, that's one of the documented use cases, phrased as asking ChatGPT to sync a routine schedule to Google Calendar as recurring events. It works because ChatGPT already has its own separate connection to your calendar. Routinery's MCP server supplies the routine data, and ChatGPT's own calendar connection is what writes the events, so both connections need to already exist for this to work.

Is Routinery the only routine app that connects to ChatGPT through MCP?

No. MCP is an open protocol, and other productivity apps, including Notion, document their own official support for it in the same way Routinery does. The connection method itself isn't unique to either app. What's specific to Routinery is what comes back once it's connected. It hands back a routine with ordered steps and a timer attached to each one, rather than a single task or a blank page waiting for you to fill it in by hand.
