MCP Expense Tracker in VS Code

Receipts, mileage and expenses that turn into invoice lines. It logs an expense with its own currency and VAT split, records the receipt by path and sha256, and emits invoice lines that are not taxed twice.

The csv or xlsx export lands in the workspace where you can open it and read the month before any of it becomes an invoice line, which is the review step the chat itself does not give you.

What you get in VS Code

You say	Tool
I paid 61.50 EUR at Media Markt for a USB hub, Acme project, billable.	`expense_add`
What did I spend this month, by category?	`expense_summary`
Give me the invoice lines to rebill Acme this month with 10% markup.	`expense_to_invoice`

The EUR 61.50 receipt above stored as amount_minor 6150, vat_rate 23, and rebilled at a net unit_price of 50.00, so the invoice did not tax it twice.

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": {
    "expense-tracker": {
      "command": "npx",
      "args": ["-y", "@theluckystrike/mcp-expense-tracker"]
    }
  }
}

Or from a terminal:

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

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-expense-tracker 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/expense-tracker 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": {
    "expense-tracker": {
      "url": "https://mcp.zovo.one/mcp/expense-tracker",
      "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: unlimited logging, 30 days of history, 3 projects, 5 rules, 200 CSV rows. 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 Expense Tracker 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.
