What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• mailbluster_list_fields

  List the brand's custom lead fields: id, label and merge tag. Use the merge tags as keys of `fields` when creating or updating leads. GET /fields.

• mailbluster_create_field

  WRITE: create a custom lead field. The merge tag is the key used in lead `fields` and in email templates. Creating a field changes the brand's data model but sends nothing. POST /fields.

• mailbluster_get_lead

  Get one lead by email address (the server computes the MD5 id MailBluster uses): name, custom fields, timezone, subscribed and opt-in status, tags, created/updated dates. MailBluster has no list-leads endpoint. GET /leads/{md5(email)}.

• mailbluster_create_lead

  WRITE: add a lead (contact) to the brand. `subscribed` defaults to FALSE: the lead is stored but is not subscribed to email. Only set subscribed=true when the person has given consent to receive email from this brand (the user is responsible for lawful consent); this server never

• mailbluster_update_lead

  WRITE: change an existing lead's name, custom fields, email, timezone, IP address, subscription flag or tags (send only what should change). `subscribed` is left alone unless you pass it; false unsubscribes the lead, true re-subscribes. Only set subscribed=true when the person ha

• mailbluster_list_products

  List product records (id, name, dates) the brand has registered for e-commerce tracking. Paged: the reply's meta has total and nextPageNo (null on the last page). GET /products.

• mailbluster_get_product

  Get one product record by the id you registered it under. GET /products/{product_id}.

• mailbluster_create_product

  WRITE: register a product record (your own id plus a name) so orders can reference it. Sends nothing to anyone and charges nothing. POST /products.

• mailbluster_update_product

  WRITE: rename a product record. PUT /products/{product_id}.

• mailbluster_list_orders

  List order records (id, currency, total price, customer lead, campaign, line items). These are records kept in MailBluster for tracking; no payment is involved. Paged: see meta.nextPageNo. GET /orders.

• mailbluster_get_order

  Get one order record by the id it was created with. GET /orders/{order_id}.

• mailbluster_create_order

  WRITE: record an order (a tracking record: it does not take payment, charge a card or send email). The customer's email becomes a lead if none exists, and the lead's tags are merged. `customer.subscribed` is REQUIRED because MailBluster would otherwise default it to true: pass fa

• mailbluster_update_order

  WRITE: change an order record's campaign, currency, total or items (send only what should change; `items`, when given, REPLACES all previous items). The customer cannot be changed here. No payment or email is involved. PUT /orders/{order_id}.
