Tools

• complete_checkout

  After the buyer approves the prepared order and total, pay its existing checkout session using a compatible Stripe payment token, including a shared payment token (spt_...). Pass the order ID as checkout_session_id; do not resend the document or addresses. On an interrupted request, retry the same checkout and token. Existing authorized, processing, or paid payments are reused; follow the returned status and messages.

  shallow
• postalform.create_form_order_draft

  Prepare a supported workflow form for mailing and return the order ID, total, hosted checkout URL, and checkout session. After buyer approval, a compatible client can use complete_checkout with a Stripe shared payment token; otherwise present the hosted checkout URL. To prepare for MPP, set payment_protocol=mpp and buyer_email; receive a PDF preview, hosted checkout_url fallback and MPP challenge, then use postalform.pay_order with the order_id after buyer approval. Draft creation never pays. For x402, use postalform.create_machine_order.

  shallow
• postalform.create_letter_order_draft

  Prepare letter text for mailing and return the order ID, total, hosted checkout URL, and checkout session. Accepts text directly; no PDF upload or browser is needed. Letter drafts may include typed or drawn signatures. After buyer approval, a compatible client can use complete_checkout with a Stripe shared payment token; otherwise present the hosted checkout URL. To prepare for MPP, set payment_protocol=mpp and buyer_email; receive a PDF preview, hosted checkout_url fallback and MPP challenge, then use postalform.pay_order with the order_id after buyer approval. Draft creation never pays. For x402, use postalform.create_machine_order.

  shallow
• postalform.create_machine_order

  Create a single PDF, letter, workflow-form order, or bulk letter campaign and pay through MPP or x402 after buyer approval. For bulk, provide exactly one of bulk.csv_content or bulk.recipients (JSON address objects with optional merge_fields), plus a shared PDF or text/HTML template. Omit top-level recipient fields and review campaign_url, recipient count and total. Bulk MPP orders can also use postalform.pay_order after fetching its challenge. The unpaid response also includes checkout_url and status_url for this same order. Without an available compatible wallet, give the buyer checkout_url and poll status_url; never recreate the order to change payment paths. Single-recipient clients with a Stripe shared payment token can instead use a draft tool followed by complete_checkout; other clients should present the hosted checkout URL.

  shallow
• postalform.create_order_draft

  Prepare an existing PDF for mailing and return the order ID, total, hosted checkout URL, and checkout session. After buyer approval, a compatible client can pass a Stripe shared payment token to complete_checkout; otherwise present the hosted checkout URL. To prepare for MPP, set payment_protocol=mpp and buyer_email; receive a PDF preview, hosted checkout_url fallback and MPP challenge, then use postalform.pay_order with the order_id after buyer approval. Draft creation never pays. For x402, use postalform.create_machine_order.

  shallow
• postalform.create_pdf_upload

  Use this when the host cannot provide a PDF file param directly. It creates a short-lived PDF upload URL and upload token (multipart/form-data, file field). Let the HTTP client generate Content-Type with its multipart boundary.

  shallow
• postalform.get_form_schema

  Use this when you need a machine-usable schema for one supported single-mailpiece PostalForm workflow (fields, groups, attachments, and dependencies).

  shallow
• postalform.get_order_status

  Read payment, processing, stored mailing/carrier status, the latest 50 public tracking events, and electronic return receipt availability. Bulk orders also return campaign_url, recipient count and per-status counts; use the campaign dashboard for individual recipients. Missing carrier evidence is null; processing or a tracking number alone does not prove mailing or delivery. This read does not pay, mail, or acquire receipts.

  shallow
• postalform.list_forms

  Use this when you need the published single-mailpiece PostalForm workflow catalog available to agents. Coordinated statutory multi-recipient workflows are excluded.

  shallow
• postalform.pay_order

  Get an MPP challenge or pay an existing MPP PDF, letter, workflow-form order, or bulk letter campaign after buyer approval. Use the order_id returned by any draft tool with payment_protocol=mpp or by create_machine_order. When switching from create_machine_order, omit the credential first to get this payment endpoint’s challenge. Review the preview or campaign_url, recipient count and total. No document or addresses are resubmitted. Without payment_authorization this only returns a challenge; with it, this can pay and send real mail. Reuse the same order_id on retries and follow the returned payment status.

  shallow
• postalform.ping

  Use this when you want a quick health check that the PostalForm MCP server is reachable.

  shallow
• postalform.preview_letter_order_draft

  Use this to prepare a non-writing preview for a mailed letter before creating checkout. It renders the letter, validates the addresses, and returns a widget with a create-draft action.

  shallow
• postalform.search_addresses

  Use this to search for a mailing address and return Loqate suggestions with IDs. Pass country_code to filter by country; it defaults to US. If a suggestion has type "Container" (building/complex), call this tool again with container=<id> and a refined query to drill down to type "Address". Only type "Address" is valid for order creation.
