Restrict Fathom call share links to people you added

A Fathom recording of a client call can be open to anyone who holds its address, and the setting is chosen call by call. Months later, nobody knows which links are still wide open.

Cotlet does it in your own Fathom account with list_calls, get_call_sharing and set_link_access, called by your AI agent, an n8n workflow or a script.

Can Fathom do this on its own?

Fathom has no bulk change for link access and no API for sharing (checked 22 Oct 2026). The API has a read-only shared_with field showing the team scope of a call, the settings page changes the default for new calls only, and neither the API reference nor the MCP overview lists a way to change link access on an existing call.

How you do it in Fathom today

  1. You open a call and click Share below the meeting title. To the left of Copy Link you pick Anyone with the link can view, Anyone on the same domain as you can view, or Only people added can view.
  2. On an Individual or Free plan the link sent to attendees is set to Anyone with the link by default, so you change it for each recording you want to restrict.
  3. On a Team plan the Default Share Link Access setting decides new calls. If it says Anyone with the link, attendees can forward the link and anyone holding it can open the recording.
  4. To cut one person off, you click Remove next to their email in the sharing details. Fathom has no way to unsend a recording already shared by email.

How to restrict Fathom call share links to people you added

Prompt

List my Fathom calls from the last 30 days that anyone with the link can open. Set them to only people added, except calls with the meeting type Public webinar, and tell me who stays on each.
  1. 01

    Find the exposed calls

    The agent lists the window with list_calls, 30 days unless you say more, and checks each call with get_call_sharing. It keeps calls whose link_access is anyone_with_link, because same_domain and only_people_added are already tight.

  2. 02

    Apply your exceptions

    Calls you named as public, for example a meeting type called Public webinar or titles with a prefix, are skipped. The agent states each skipped call and the rule that skipped it, so a public call never gets locked by mistake.

  3. 03

    Read who is on the list

    Before changing a call, it keeps the people list from get_call_sharing. Switching to only_people_added leaves added people in place, so the report shows who still has access afterwards.

  4. 04

    Switch the link

    set_link_access sets only_people_added on each remaining call. It waits for your OK by default, because a link a customer relies on stops working for people who were not added.

  5. 05

    Check the result

    The agent reads get_call_sharing again for each changed call and reports any call where the setting did not stick, for example one where your role cannot see the sharing details.

What you get back

Example data

Calls in the last 30 days: 41
Open to anyone with the link: 17
Restricted 14, e.g. "Q4 pricing review" (3 people added)
Skipped 2 (meeting type Public webinar)
Not changed 1: "Vendor onboarding sync", sharing details hidden at Limited access

Other ways to ask

  • Run on the 1st of every month and restrict last month's calls recorded with external attendees.
  • Only report calls open to anyone with the link, with who is added, and change nothing.
  • Set same_domain, not only people added, for calls recorded by my team this quarter.

What Fathom allows, and what to know first

  • Fathom's three link choices are Anyone with the link can view, Anyone on the same domain as you can view and Only people added can view.
  • Fathom documents three access levels for a person on a call: Limited sees transcript, summary and recording, Standard also downloads and sees highlights and action items, and Admin also shares and trims.
  • Auto-share sends the summary or recording to every attendee on the calendar invite, including people who did not attend, so the link reaches them before you act.
  • On a Team plan, a call set to Anyone with the link stays open to everyone holding it, including people attendees forward it to.

set_link_access asks for your OK by default. To run it weekly without you, switch confirmation off for that tool in your dashboard.
