Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

calculate
calculate_totals
Compute subtotal, discount, tax and total for a list of line items (discount applied before tax, amounts rounded to 2 dp). Use for quick totals math without building an invoice. Do NOT use to produce an invoice document; use create_invoice.
invoice
create_invoice
Build a complete invoice as structured data: invoice number, issue and due dates, line items, discount, tax, total and payment terms. Nothing is stored. Use when the user wants an invoice for a client. Do NOT use for totals only (use calculate_totals) or for a printable text version (use render_invoice_text).
render
render_invoice_text
Build an invoice from the same inputs as create_invoice and return it as a plain-text document (header, line items, subtotal, discount, tax, TOTAL DUE, notes) ready to paste into an email or message. Use when the user wants readable invoice text. Do NOT use when structured fields are needed; use create_invoice.
supported
supported_currencies
List the currency codes InvoiceGen accepts for invoices (USD, EUR, INR, GBP, AED, SGD, AUD, CAD). Use before create_invoice when unsure whether a currency is supported. No exchange rates or currency conversion are provided.

InvoiceGen — questions

Answers built from our own checks of this server.

What can InvoiceGen do?
It exposes 4 tools, read directly from the server on our last check. Among them: calculate_totals, create_invoice, render_invoice_text, supported_currencies. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is InvoiceGen working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 109 ms. The bar chart above shows every period we have measured.
How do I connect InvoiceGen?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does InvoiceGen need an API key?
No. InvoiceGen completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is InvoiceGen?
It answers our handshake in 109 ms on average, which is faster than 81% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is InvoiceGen open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
