Cyberimpact MCP by usefulapi missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

cyberimpact

cyberimpact_add_member

WRITE: add a contact as a subscribed member WITHOUT a confirmation email (implied consent) and put it in the given groups; the contact can then be mailed. Only use it for people who really gave their consent (CASL); to ask the person to confirm first use cyberimpact_send_optin. A member that already exists is rejected by the API. Throttled by Cyberimpact; for many contacts use the app's import. POST /members.

cyberimpact_add_member_to_groups

WRITE: add an existing member to more groups (existing group memberships are kept). Being in a group makes the member a recipient of mailings sent to it. Returns the member's groups after the update. POST /members/{key}/groups.

cyberimpact_create_group

WRITE: create a new, empty group (mailing list). A public group can be offered on subscription forms; a private one is internal. Groups cannot be deleted through this server. POST /groups.

cyberimpact_create_mailing

WRITE, SENDS EMAIL TO CUSTOMERS: create a mailing scheduled to be sent at send_at to every member of the chosen groups. It goes out for real unless it is cancelled in the Cyberimpact app before send_at. Only call it after the user has approved the subject, body, sender and groups, and set confirm_send to true. mail_from must be a validated sender address of the account. A mailing cannot be deleted through this server. POST /mailings.

cyberimpact_create_template

WRITE: create a new email template from HTML and/or text. It is only saved in the account; nothing is sent. POST /templates.

cyberimpact_get_member_groups

The groups a member belongs to (id, title, public/private, dynamic). GET /members/{key}/groups.

cyberimpact_get_member_mailings

The mailings a member received (use it to see what a contact was sent and when). GET /members/{key}/mailings.

cyberimpact_get_template

One template by id with its HTML and text body (cut at 20 000 characters). GET /templates/{id}.

cyberimpact_list_bounced_members

Members whose last mailing hard-bounced (invalid addresses to clean up), with the bounce date. GET /members/bounced.

cyberimpact_list_custom_fields

The account's custom member fields (id, name, type text/date/integer/decimal). Member customFields are keyed by these ids. GET /customfields.

List the account's groups (mailing lists) with member and mailing counts, public/private and dynamic flags. Use the ids to target mailings and opt-ins. GET /groups.

cyberimpact_list_mailing_recipients

Who received a mailing and what happened: kind = all, delivered, stopped, hard_bounced, soft_bounced, unsubscribed, opened or clicked. Optionally only recipients from one group. GET /mailings/{id}/recipients[/{kind}].

cyberimpact_list_mailings

List mailings by state: sent (default, archived ones excluded), scheduled (queued to go out) or archived. Each has id, subject, language, send/schedule date, recipient count and sender. Optionally only mailings sent to one group. GET /mailings/{sent|scheduled|archived}.

cyberimpact_list_members

List subscribed contacts (members) with name, email, language, consent type, mailing counts and custom fields. status: active (in at least one group, default), orphans (in no group) or all.
