Key takeaways

The short version.

  • Catholic Reminders supplies the week's feasts, holy days, fast and abstinence days and Mass reading citations with USCCB links. It gives citations and links, not the full text of the readings.
  • Lindy's documentation describes custom MCP servers added by a public HTTPS address, and routines that run daily, weekly or monthly, with a dry run to preview what would happen.
  • Lindy runs the Sunday check and writes the summary. The app supplies the calendar facts. You check anything important with your parish or diocese.
  • Nothing here is a listing or built-in integration with Lindy, and this setup has not been tested end to end. You add the address yourself.
  • Sending to a family or parish group is a manual step: the agent messages you, and you forward the summary.

  • The app knows the calendar.

It is for people who want the week's Church calendar in front of them before it starts: parents setting the week for their children, catechists, parish volunteers, and anyone who likes to know about a fast day or a feast in advance.

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. Lindy builds AI agents that run work automations on a schedule.

The app knows the calendar. A scheduled Lindy agent asks on your behalf and sends you the result.

Use cases

5 ways people use Catholic Reminders + Lindy.

  1. Sunday agent

    1. A Sunday-evening week-ahead message

    Lindy's routines page says routines can run daily, weekly or monthly, and that a new routine defaults to 9:00 AM daily until you change it. Choose a weekly schedule on Sunday evening. Give the agent a plain instruction: ask Catholic Reminders for the coming week and send me the feasts, holy days and any fast or abstinence days.

    Ask for one line per day, so the message reads quickly.

  2. Fast days

    2. Fast and abstinence days before they arrive

    The app flags fast and abstinence days ahead of time. Tell the agent to list them first, with the date, so a Friday or a fast day does not catch the household by surprise.

    Local practice can differ, and your own circumstances matter. Confirm important dates with your parish or diocese, and speak with your priest about questions of conscience.

  3. Reading citations

    3. Reading citations with links, not full text

    For the Sunday Mass and the weekdays, the app returns reading citations with USCCB links. It does not reproduce the readings. Ask the agent to send the citations and links exactly as returned, so you can open and read the passages yourself.

    Tell the agent not to summarize or explain the readings from memory. If you want an explanation, ask for one separately and check it against Church sources.

  4. Delivery

    4. Choose where the message arrives

    Lindy's routines page names Lindy chat, a text message (if your phone is verified) and a Slack direct message as delivery channels for a personal routine, and a phone call within calling hours. It does not list email, and it describes no delivery to a family or parish group beyond Slack channels for workspace routines.

    So the practical route is a message to you. To share it, forward or copy it to your family or parish group yourself.

  5. Dry run

    5. Check the first runs with a dry run

    Lindy's dry run shows what a routine would have sent without sending it. Use it to check that the week looks right and that nothing is padded or invented. The page says a dry run cannot test the delivery step, so send the first real message to yourself.

    Compare the first few weeks with the app's own week view until you trust the instruction.

How to

How do I set up the Sunday agent with Lindy?

  1. 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.

  2. Step 2

    In Lindy, open Integrations, choose + Add, then MCP. Enter the server URL and a display name. Under Advanced, add the token as a bearer token, custom header or query parameter. Click Connect.

  3. Step 3

    Under Guardrails choose Ask for approval or Always allow, and turn off any tool you do not need.

  4. Step 4

    Create a routine on a weekly Sunday-evening schedule with the instruction to send the week's feasts, fast days and reading citations. Run a dry run.

  5. Step 5

    Pick a delivery channel such as Lindy chat, text or Slack, and send the first message to yourself. Forward it to a group by hand if you wish.

Lindy describes custom MCP servers in its documentation, which says the server must be a public HTTPS streamable-HTTP endpoint and does not say which plans include it. Schedules, dry runs and delivery options are on its routines page. Menus can change. If you cannot add the connection, use the app's own reminders. Catholic Reminders is not listed by Lindy or built into it.

FAQ

Frequently asked questions.

Is Catholic Reminders an official Lindy integration?

No. There is no partnership, listing or built-in integration. Lindy lets you add a custom MCP server by its address, and you add the app's address yourself. The app is an AgentStructure.AI app.

Can Lindy email the week to me or my parish group?

That was not confirmed. Lindy's routines page lists Lindy chat, text message, Slack and a phone call for personal routines, not email, and no group delivery. Use a listed channel and forward the message yourself.

Does the app give me the full text of the readings?

No. It gives citations and USCCB links. Open the links to read the passages.

What if I cannot add the connection?

Use Catholic Reminders directly. The app has its own reminders and a week view, so the calendar still reaches you without Lindy.

What does it cost?

The apps are free during the beta, and the site shows the free and premium parts. Lindy has its own plans and credits, so check its pricing page.
