MCP Invoice in Claude Code

Numbered invoices with tax lines, rendered to a PDF. It stores your business profile and clients, allocates numbers that never repeat, computes per-line rounding and several VAT rates in integer minor units, and renders an A4 PDF.

The whole month closes in one terminal session: hours out of the time tracker, receipts out of the expense tracker, one invoice_create, one invoice_pdf. That chain was six tool calls and 53 seconds in the audit.

What you get in Claude Code

You say	Tool
Invoice Acme for 12 hours at 90 EUR plus 300 EUR setup, 23% VAT, PDF.	`invoice_create then invoice_pdf`
Which invoices are unpaid and overdue?	`overdue_report`
Mark INV-2026-0007 as paid in full.	`invoice_mark_paid`

In the audit run this issued INV-2026-0001: subtotal EUR 275.00, 23% VAT EUR 63.25, total EUR 338.25. The file on disk began with %PDF-1.3 at 2,495 bytes.

Install it in Claude Code

The file is .mcp.json, and the key inside it is mcpServers.

Scope	Path
local (default)	`~/.claude.json, this project only`
project	`.mcp.json at the repository root`
user	`~/.claude.json, every project`

If you also run Claude Desktop, the shortest path there is one click: invoice.mcpb from the bundle catalog opens as an extension, with no JSON and no terminal. Claude Code reads its own config, so here it is:

From the terminal, against a built file:

claude mcp add --scope user invoice -- node /absolute/path/to/mcp-servers/servers/invoice/dist/index.js
claude mcp list    # health-check it before the first prompt

# or --scope project, committed to .mcp.json for the team

The node command above wants a built file. From a clone, once:

git clone https://github.com/theluckystrike/mcp-servers.git
cd mcp-servers && npm install
npm run build -w packages/mcp-license -w servers/invoice

That writes servers/invoice/dist/index.js, and its absolute path is the one argument the config needs.

The npm packages are not published yet, so the form below returns a 404 today. It is here because it is what the entry becomes the day the publish lands, with nothing else changed:

claude mcp add invoice -- npx -y @theluckystrike/mcp-invoice

No restart. The entry is picked up in the next session, and `/mcp` reconnects one on demand.

Nothing is published to npm yet, so the working install paths are the ones above: the .mcpb bundle from the bundle catalog, a clone and build, or the hosted URL.

No install: the hosted endpoint

The same server runs at https://mcp.zovo.one/mcp/invoice over MCP streamable HTTP, no install. Mint a free token with curl https://mcp.zovo.one/mcp/token, or use a Pro key. It has no filesystem, so a file comes back as a one-hour download link.

claude mcp add --transport http invoice https://mcp.zovo.one/mcp/invoice \
  --header "Authorization: Bearer <token>"

Claude Code notes worth knowing first

The `--` is load-bearing: it separates Claude Code's own options, such as --transport, --env and --scope, from the command that runs the server. And the default scope is local, private to you and to the directory you ran it in, so adding it in the wrong folder leaves the tools absent with no error at all.

Free: 3 invoices a month with a small footer line, overdue report included. Pro is $19 once, verified offline.

Questions

Which scope should I use for MCP Invoice?

Local, the default, writes ~/.claude.json and is private to you and that directory. --scope project writes .mcp.json at the repository root, shared through version control. --scope user loads it everywhere.

Why did my first prompt ignore the server?

Measured, not documented: of three fresh projects, one first prompt made zero tool calls although initialize answered in 1.05 seconds. Run claude mcp list once first: it prints Connected, and the next run used the tool.

Can I use MCP Invoice without installing anything?

Yes: claude mcp add --transport http invoice https://mcp.zovo.one/mcp/invoice --header "Authorization: Bearer <token>". Mint a free token at https://mcp.zovo.one/mcp/token or use a Pro key. -t and -H are the short forms.
