Thank you for your business!
No SDK to install, no schema to learn, no API keys to paste into chat. Add the MCP server, sign in with one browser click, and you're billing in the same sentence you'd use over Slack.
System // 001
Step 01
One terminal command for Claude Code, or paste a six-line block into .mcp.json for Cursor, Codex, Windsurf, VS Code, or any MCP-compatible client. The command contains no secret — safe to paste into chat or screenshare.
Step 02
Run /mcp → orizu → Authenticate. Your browser pops to Orizu, you click Allow, and the OAuth token is cached locally by your client. No keys to copy, no headers to manage, no secrets in your chat history.
Step 03
“Bill Acme £4,500 for last month, due in 14 days, with a Stripe link.” Your agent drafts, marks paid, hands you share-links for clients, and surfaces overdue accounts — no UI required.
Agent-Native // 007
Orizu ships an MCP server with 33 tools — draft, schedule, remind, reconcile, report, server-render PDFs, self-diagnose. Paste the prompt on the right into Claude, ChatGPT, or any MCP-capable agent. Bill clients in plain English.
MCP tools
Prompt to install
You are my invoicing agent. Connect to Orizu's MCP at: https://orizustudio.co.uk/products/ai-invoice-generator/api/mcp Your MCP client (Claude, Cursor, ChatGPT, etc.) will open a browser the first time so I can sign in to Orizu — once. After that the connection stays authenticated automatically. No API keys to copy or paste. When I describe a job — client, amount, terms — draft the invoice, issue it, and return the public payment link. Default currency GBP. Default net-14. If I say "remind me", set a scheduled reminder. If I say "recurring", set up the schedule. Never send without showing me the draft first.
The first connection opens a browser to sign in to Orizu — once. After that, your agent stays connected automatically. Building a CI/headless integration? Mint an API key from your dashboard.
This isn't a marketing animation — it's the exact MCP tool sequence Claude, Cursor, ChatGPT Desktop and Codex run when you ask them to bill a client. Plain English in, real invoice out.

Prompt Cookbook // 008

“I've tried every invoicing tool out there. Then I plugged Orizu's MCP server into Claude — and billing became a one-liner. Now I just say ‘draft an invoice for Northbound, £3,200, due in 14 days’ and a hosted PDF lands, ready to share. Total game-changer.”
Marcus Bennett
Freelance Developer
“Our studio runs invoicing through Cursor now. I describe what we shipped, the agent drafts five invoices off the timesheet, I hit approve. What used to be a Friday afternoon is twenty minutes.”
Maya Okonkwo
“I connected the MCP server to Claude in one browser click — no API keys, no config. Now I just say "chase everything overdue" and it sends the reminders. My agent runs the boring half of my business.”
Dan Reichert
“ChatGPT does my month-end over MCP. "Summarise what's unpaid and mark the Hermes invoice paid" — done in one prompt. The 33 tools mean the agent can actually finish the job, not just draft it.”
Priya Shankar
“I just tell Claude "draft an invoice for the Meridian rebrand, 4 days at £750" and it's done — line items, totals, a hosted PDF ready to send. I haven't touched a spreadsheet template in months.”

FAQ // 002
Anything that speaks the Model Context Protocol (MCP) — Claude Desktop, Claude Code, Hermes, OpenClaw, ChatGPT Desktop, Cursor, and the rest. Once you've added Orizu's MCP server to the agent's config, you talk to it like you'd talk to any other tool — in plain English.
Our MCP server exposes a full toolkit: draft a new invoice with line items, tax and currency; list all invoices or just overdue ones; mark invoices sent or paid; update line items, dates and totals; attach a Stripe payment link; delete drafts; and — when a user asks "Can you send me a copy of the invoice?" — return a hosted PDF link valid for 90 days that the client can open in any browser. So "Bill Acme £4,500 for last month, due in 14 days, with a Stripe link" turns into a real invoice in seconds.
Generate a PDF API key in the Developer section of your dashboard, then paste Orizu's MCP server URL into your agent's config (Claude Desktop's claude_desktop_config.json, Cursor's settings, etc.). Setup takes about a minute. Quick-start guides for the most popular agents are on the way.
Yes. Every agent call uses your own PDF API key and is scoped to your rows in the database — enforced at the database layer via row-level security. The agent only sees what you would see logged in yourself. We don't train any model on your invoices and we never share your data with third parties.
Absolutely. The web editor and PDF download work without ever touching the AI side. You can also use the REST PDF API directly from any backend or no-code tool with a Bearer token. The MCP is an option, not a requirement.
You send it to them yourself, through the channel you already use — email, Slack, WhatsApp, your project-management tool. Orizu hands you two delivery formats and you choose: (1) a one-click PDF download from any invoice row in the dashboard, or (2) a public-but-unguessable share URL (valid 90 days) anyone can open in a browser. Your agent can return either format on request via the get_invoice_pdf_url tool. We deliberately don't send email to your clients ourselves — keeps you in control of the From address, the cover note, and the conversation thread.
Yes — connect your Stripe account once in the Integrations tab and every invoice can auto-generate a Pay-now link. Your agent can attach a Stripe link to any invoice via attach_payment_link, and when the payment lands Stripe pings us and the invoice flips to Paid without you lifting a finger.
Yes — 3 invoices per month, PDF download, single user, basic templates, plus 150 MCP calls per month so you can connect an AI agent (Claude, Cursor, ChatGPT) and actually try it. The REST API and API keys are a paid feature; upgrade when you want unlimited invoices, the REST endpoints, and higher call limits.
