MCP Invoice in VS 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 server writes the PDF itself, so it lands at the path you named inside the workspace and shows up in the Explorer, rather than in a preview you then have to save.

What you get in VS 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 VS Code

The file is .vscode/mcp.json, and the key inside it is servers.

Scope	Path
This workspace	`<workspace>/.vscode/mcp.json`
Every workspace	`the user profile mcp.json, opened by the MCP: Open User Configuration command`

// .vscode/mcp.json  (the key is "servers")
{
  "servers": {
    "invoice": {
      "command": "npx",
      "args": ["-y", "@theluckystrike/mcp-invoice"]
    }
  }
}

Or from a terminal:

code --add-mcp '{"name":"invoice","command":"npx","args":["-y","@theluckystrike/mcp-invoice"]}'

VS Code asks you to confirm you trust the server and its capabilities before it starts. Nothing runs until you answer.

The npm publish of @theluckystrike/mcp-invoice is pending; until then use the .mcpb bundle or a clone and build from the latest release.

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.

{
  "servers": {
    "invoice": {
      "url": "https://mcp.zovo.one/mcp/invoice",
      "headers": { "Authorization": "Bearer <token>" }
    }
  }
}

VS Code notes worth knowing first

The top-level key is "servers", not "mcpServers". A config pasted from a Claude Desktop or Cursor README parses cleanly, contributes no servers, and gives you no error to read, which makes it the most expensive one-word mistake here. Alongside it an "inputs" array holds secrets. The newer Agent Host reads a workspace .mcp.json instead.

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

Questions

Why does my mcp.json do nothing?

The key is servers, not mcpServers. A config copied from a Claude Desktop README parses cleanly and contributes nothing. Rename it. On the newer Agent Host, use a workspace .mcp.json instead.

Do I have to edit the file at all?

No. code --add-mcp takes the server object on the command line, and MCP: Add Server in the palette asks whether the target is Workspace or Global.

Where do the MCP Invoice tools show up?

In Chat, behind the tools picker, once the server has started. Adding or changing one raises a prompt asking you to confirm you trust it; if the picker is empty, that prompt is usually still waiting.
