Find Contact

Look up a contact in your Loops audience by email address or user ID. Returns the full contact record including all standard and custom properties, mailing list subscriptions, and opt-in status.

list_mailing_lists

List Mailing Lists

Retrieve all mailing lists configured in your Loops account. Returns each list's ID, name, description, and visibility. Useful for discovering list IDs needed when subscribing contacts to lists.

create_contact

Create Contact

Create a new contact in your Loops audience. Contacts are identified by email address and can include standard properties (name, subscription status, user group) as well as custom properties. Use mailing list subscriptions to add the contact to specific lists on creation.

list_contact_properties

List Contact Properties

Retrieve all contact properties defined on your Loops account. Returns both default properties (email, firstName, etc.) and custom properties with their key, label, and type. Useful for discovering available property keys when creating or updating contacts.

Permanently delete a contact from your Loops audience. Identify the contact by email address or user ID.

check_contact_suppression

Check Contact Suppression

Read whether a contact is suppressed and its suppression-removal quota. This lookup does not remove suppression or resubscribe the contact.

get_current_team

Get Current Team

Verify the connected API key and return its Loops team name. The API does not provide a team ID through this endpoint.

Connect Loopsso to your AI client

Every client uses the same Magic MCP URL, and so does any other MCP client. Add it once and sign in with SSO.

  1. Enable Loopsso in Metorial. In your Metorial portal, enable the Loopsso MCP server and sign in with the account that owns the data. Access stays governed by your team policies.
  2. Add a custom connector. Open Customize, then Connectors. Select Add, then Custom, then Web.
  3. Paste your Metorial MCP URL. Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>) and continue.
  4. Sign in. Select Add and sign in to load Loopsso tools.

Run Loopsso through the Metorial gateway

One governed layer for every app your agents reach, not a separate connector per tool.

  • Give Loopsso and every other app to your whole team through one MCP gateway, behind your SSO.
  • Scope which teams and agents can use Loopsso tools with role-based access control, and trace every call.
  • Prefer to run it yourself? Metorial is open source and self-hostable.
