Overview

AI-generated overview

Remote MCP endpoint that lets an assistant generate invoice and receipt PDFs from JSON, with a free demo quota or an API key for higher plan quotas.

What you can do
  • Generate invoice PDFs from JSON data supplied by the assistant.
  • Generate receipt PDFs from JSON data.
  • Call a document-generation API directly as an agent, with quota tied to the caller's plan or IP.
When to use it
Useful when an assistant needs to turn structured billing data into finished invoice or receipt PDFs without a local toolchain, for example in small business or bookkeeping workflows.
Requirements
A remote MCP endpoint at slipstack.dev over streamable HTTP; no local package or runtime is needed. An optional Authorization header with a Bearer API key (psk_...) raises quotas; without it a free demo quota of 10 documents per day per IP applies.
Before you install
The Authorization header carries a secret API key, so keep it out of logs and shared configs. Generated documents contain billing data sent to a third-party service; check that this is acceptable for the customer information involved. Without a key, usage is limited and tied to the caller's IP.

Installation

In SourceWeft

  1. Open Slipstack PDF in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.slipstack%2Fpdf/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Parametersdatarequiredapi_keyoptions

create_einvoice_xml

Create EN 16931 e-invoice XML

Generate an EN 16931 e-invoice as UN/CEFACT Cross-Industry Invoice (CII) XML — the format behind France's Factur-X and Germany's XRechnung mandates. Same JSON shape as create_invoice_pdf plus a few extra fields: from/to countryCode (required), from.vatId (required when taxRate > 0), optional paymentIban, paymentReference, buyerReference. Returns a 24-hour download URL for the XML plus computed totals. Validated against the official EN 16931 schematron in CI.

Parametersdatarequiredapi_keyoptions

parse_einvoice

Parse an e-invoice (CII or UBL)

Parse EN 16931 e-invoice XML — UN/CEFACT CII (Factur-X, ZUGFeRD, XRechnung) or UBL Invoice/CreditNote (Peppol BIS) — into normalized invoice JSON: parties, line items, totals, VAT ids, payment details. Pass the XML document as a string.

Parametersxmlrequiredapi_key

get_document_schema

Get document schema

Returns the JSON shape accepted by create_invoice_pdf / create_receipt_pdf / create_einvoice_xml, a complete example payload, and current plan limits. Call this first if you are unsure how to structure a document.

Takes no parameters.

get_api_key

Get a free API key

Issue a free Slipstack API key (50 documents/month) for an email address, returned directly in the response — no signup flow, no email verification step. Idempotent: the same email always gets the same key back. Use the key as api_key on other tools or as an Authorization: Bearer header. Paid plans (from $19/mo for 1000 documents): https://buy.stripe.com/eVqeVcaEa9xFdnudDeew80n
