Capabilities

Tools 17

superphone_add_contact_tags

WRITE: apply tags to a contact, by name (a new name creates the tag) or by tag id. Tags can drive automations in Superphone. Returns the contact with its tags. GraphQL mutations `addContactTagsByNames` / `addContactTags`.

Discovered
superphone_add_contribution

WRITE: record a purchase or donation against a contact (name, amount, date). It adds to the contact's total spent and cannot be undone with this server. Returns the new contribution. GraphQL mutation `createCustomContribution`.

Discovered
superphone_create_contact

WRITE: create a contact (first name required; add a mobile number or email so it can be reached). Creating a contact does not send it a message. Returns the new contact. GraphQL mutation `createContact`.

Discovered
superphone_find_contact

Find one contact by exact mobile number or email address (give at least one; E.164 such as +12132679977 is best). Returns the full contact or null when none matches. GraphQL query `contactByIdentifier`.

Discovered
superphone_get_account

The Superphone account behind the API key: user id, email, name, the business phone numbers (number, default/active flags, short code) and notification preferences. GraphQL query `me`.

Discovered
superphone_get_contact

One contact by id with every profile field, tags, custom contributions (recorded purchases) and its latest 10 conversations (ids to read with superphone_get_conversation). GraphQL query `contact`.

Discovered
superphone_get_conversation

One conversation with its most recent messages (default 20, newest last): body, from/to, direction (INCOMING_TEXT, OUTGOING_TEXT, SYSTEM, calls), delivery status, errors and media. To read older messages pass `before` = the previous reply's previous_cursor. GraphQL query `conversation`.

Discovered
superphone_get_form

One sign-up form by id, or the account's default form when form_id is omitted. GraphQL queries `form` / `defaultForm`.

Discovered
superphone_get_message

One message by id: body, from/to, direction, delivery status, error and media. GraphQL query `message`.

Discovered
superphone_list_contacts

List the SMS contacts (the subscriber list) with name, mobile, email, company, VIP/hidden/archived/unsubscribed/opted-out flags, total spent, creation date and tags (up to 20). Oldest first; page with next_cursor. `total` is the size of the whole list. GraphQL query `contacts`.

Discovered
superphone_list_conversations

List text conversations (the inbox): id, participant number, platform (TWILIO = SMS, FACEBOOK = Messenger), hidden/archived flags, creation date and the contact. Page with next_cursor. Read the messages of one with superphone_get_conversation. GraphQL query `conversations`.

Discovered
superphone_list_forms

List the sign-up (opt-in) forms: id, public hashId, domain, titles, opt-in text flag, optional fields, redirect URL, default and enabled flags. GraphQL query `forms`.

Discovered
superphone_list_webhooks

List the configured webhooks: id, destination URL, active flag and subscribed events (CONTACT_ADDED, CONTACT_UPDATED, CONTACT_TAGS_CHANGED, MESSAGE_RECEIVED, MESSAGE_SENT, MESSAGE_STATUS_UPDATED). GraphQL query `webhooks`.

Discovered
superphone_remove_contact_tags

WRITE: remove tags from a contact, by name or by tag id. This can take the contact out of tag-driven segments and automations. Returns the contact with its remaining tags. GraphQL mutations `removeContactTagsByNames` / `removeContactTags`.

Discovered
superphone_search_numbers

Search phone numbers that could be bought for the account, optionally starting with some digits (for example an area code), with their price. Read-only: this tool never buys a number. GraphQL query `searchNumbers`.

Discovered
superphone_send_message

WRITE, IRREVERSIBLE: send a real text message to a customer from the account's number. It is delivered immediately, uses the account's messaging credits and cannot be recalled. Only send what the user explicitly asked for, to the number they named, and never to contacts who unsubscribed or opted out. Give exactly one of conversation_id (reply in an existing conversation) or mobile (a number, ideally E.164 like +12132679977; without a country code Superphone assumes the US). Returns the new message id. GraphQL mutation `sendMessage`.

Discovered
superphone_update_contact

WRITE: change fields of an existing contact. Only the fields you pass change: the tool first reads the contact and sends the full record back with your changes (the API requires the first name on every update). Pass an empty string to clear a text field. Returns the updated contact. GraphQL mutation `updateContact`.
