Key takeaways
The short version.
- Catholic Reminders supplies the week's feasts, holy days, fast and abstinence days and Mass obligations, plus reading citations with USCCB links.
- Claude can add Catholic Reminders as a custom connector using its remote MCP address, and its connector settings accept a fixed key as a request header.
- Claude plans and writes. The app supplies the calendar facts. You check the plan against your parish or diocese.
- Nothing here is an official listing, partnership or built-in integration with Claude. You add the address yourself.
- The calendar is the U.S. Roman calendar, and the readings come as citations and links, not full text.

The app knows the calendar.
It is for people who organize other people around the Church year: parents setting the week for their children, catechists and religious education teachers, parish staff and volunteers, a bulletin or newsletter writer, RCIA team members and anyone who wants fasting days and feasts in their own calendar before they arrive.
Catholic Reminders is an independent Catholic resource. It delivers the liturgical calendar, feast days, saints, readings and context for what is happening in the Church. It is not endorsed by the Vatican, the USCCB or the Catholic Church. Claude is Anthropic's AI assistant, and it is good at turning a list of facts into a plan or a short note.
The app knows the calendar. Claude helps you shape it around the people you are planning for.
Use cases
5 ways people use Catholic Reminders + Claude.
- Family weekFamily week
1. Lay out the family week
Catholic Reminders has a week view with the upcoming days flagged: feasts, holy days, and fast and abstinence days. Ask Claude, through the connector, to turn it into one line per day, with a note on what each day asks of the household.
Then add your own details in the chat: school pickups, sports, a grandparent's visit. Claude can fit the Church calendar into them. Keep the list short enough to stick on the fridge.
- Sunday readingsSunday readings
2. Prepare the Sunday readings
The app's Mass companion returns reading citations with USCCB links for a date. It gives citations and links, not the text of the readings and not commentary.
Ask Claude to list the citations, open the links and read the passages yourself. Then ask for two or three questions to talk over at the dinner table, based only on what you pasted back from your reading.
- Fasting daysFasting days
3. Plan meals and reminders around fasting days
The app flags fast and abstinence days ahead of time. Ask Claude to check the next month for them and write a short list you can paste into your calendar or shopping notes.
Local practice can differ, and your own circumstances matter. If a date is important, confirm it with your parish or diocese, and speak with your priest about questions of conscience.
- Weekly noticeWeekly notice
4. Draft the parish or class notice
A parish office or a catechist often writes the same weekly note: what is coming, when, and what to bring. Give Claude the week's feasts and holy days from the app, plus your own Mass times and events, and ask for a friendly three-paragraph notice.
Keep the two kinds of material apart when you review it. The Church calendar comes from the app. Mass times and events come from you.
- Faith questionsFaith questions
5. Ask a faith question and pass along the answer faithfully
Catholic Reminders answers teaching questions from its reviewed knowledge base. When a question is not covered, it says it is unsure and does not generate doctrine.
Ask Claude to relay that answer as it is and to say so when the app is unsure. For anything serious, talk with your priest or a trusted teacher.

How to
How do I connect Catholic Reminders to Claude?
Step 1
Sign up free at [catholicreminders.org](https://catholicreminders.org), open the Connect your AI page and create a personal token. Save it, because it is secret. The remote MCP address is https://catholicreminders.org/api/mcp.
Step 2
In Claude, go to Customize, then Connectors, and add a custom connector with a name and that address. The app uses a token, not a sign-in flow, so add a request header: X-API-Key, or Authorization with the bearer token.
Step 3
On a Team or Enterprise plan an organization owner adds the connector first, then each member connects. A header value is shared by everyone on the connector, so use a token meant for that.
Step 4
Start a chat and ask what this week means in the Church calendar. Review the tool requests Claude shows before you approve them, then ask for your plan.
Custom connectors are described in Anthropic's help center. Plans and menus can change, so follow that page. Catholic Reminders is not listed in Claude's directory or built into Claude.
