Tools

16 tools listed at last check
  • openphone_list_phone_numbers List the OpenPhone numbers in the workspace (id, number, name, formatted number, assigned users, restrictions). Usually the first call — most other tools need a phoneNumberId. OpenPhone REST: GET /phone-numbers.
  • openphone_list_users List workspace users (id, email, name, role). Use to find a userId for scoping other calls. OpenPhone REST: GET /users.
  • openphone_list_contacts List contacts in the workspace, optionally filtered by external ids or sources. Returns each contact's default fields (name, company, emails, phone numbers) and custom fields. OpenPhone REST: GET /contacts.
  • openphone_get_contact Get a single contact by its id, including default fields (name, company, role, emails, phone numbers) and custom fields. OpenPhone REST: GET /contacts/{id}.
  • openphone_get_contact_custom_fields List the workspace's contact custom-field definitions (name, key, type). Use the returned keys when creating contacts with custom fields. OpenPhone REST: GET /contact-custom-fields.

  • openphone_get_call_transcript Get the transcription for a call by its id — dialogue segments with speaker, text and timestamps, plus overall status and duration. OpenPhone REST: GET /call-transcripts/{id}.
