Two ways to run it, both free to start. Open mcp.zovo.one/mcp/connect, copy the deposits URL and paste it into any client that takes a URL. It already carries a free token, so there is nothing to install, no account and no header to set. The URL is https://mcp.zovo.one/mcp/deposits/t/<token>. The token is not optional: the bare https://mcp.zovo.one/mcp/deposits connects and lists its tools and then answers every tool call with HTTP 401, so use the link from /mcp/connect or send Authorization: Bearer <token>. Or download deposits.mcpb and double-click it in Claude Desktop.

mcp-deposits

Security and retainer deposits, held per client, on the same engine as your invoices.

A deposit is the client's money sitting on your account. It has to be recorded when it arrives, set against an invoice when the work is billed, given back when it is not, and answered for at any point in between: how much of theirs are you holding, in which currency, since when. This server does those four things, against the invoices and the clients the mcp-invoice server already holds. When a deposit is applied to an invoice, the payment is recorded on that invoice, so invoice_list and overdue_report stop chasing money you already have. Everything stays on your machine.

Built on @theluckystrike/mcp-invoice/lib for the money, currency and store code, and on @theluckystrike/mcp-billing-docs/lib for the A4 page, so a deposit statement looks like the credit note and the invoice next to it and agrees with them to the minor unit.

In the official MCP Registry (io.github.theluckystrike/deposits).

deposits demo

npm publish for @theluckystrike/mcp-deposits is pending, so npx -y @theluckystrike/mcp-deposits returns 404 today. Until then, the .mcpb one-click bundle or a clone+build is the working path.

Install

Claude Desktop (claude_desktop_config.json):

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

Claude Code:

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

Cursor (.cursor/mcp.json):

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

Run mcp-invoice alongside it: this server reads that server's invoices and clients, writes the payment an applied deposit makes onto the invoice, and both take their name, address, VAT id and default currency from one shared business profile.

The free cap is on recording new deposits only. Money already held can always be applied, refunded and accounted for, on any tier: a limit that trapped a client's deposit would be a limit on their money, not on yours.

The cap counts the deposits stored with a received date in that month, so deposit_delete gives the slot straight back: a deposit typed in twice or with the wrong amount costs nothing but the id. deposit_record also refuses a deposit that matches one already stored on client, amount, currency, kind, received date and reference, names that id and stores nothing, so the same money is never held twice and no free slot is spent on a retry.

A measured thing

The invoice server's own payment tool SETS the amount paid, so routing a deposit through it erases the payment that came before. Measured against servers/invoice/dist/index.js on a EUR 1,000.00 invoice: invoice_mark_paid {amount: 200} for a bank transfer, then invoice_mark_paid {amount: 300} for the deposit, leaves paid_minor at 30000 and the reply reads "balance due EUR 700.00". The EUR 200.00 that actually arrived is gone from the record, and the client gets chased for it.

deposit_apply writes the same three fields on the same record, paid_minor, paid_date, status, but ADDS: the same two payments leave paid_minor at 50000 and a balance due of EUR 500.00. Asserted in test/unit.test.mjs, "a second application ADDS to paid_minor, it does not replace it".

The general form: a store shared between two servers is safe to write only if you have read how the owning server writes it. The field names matching is not the contract; the arithmetic on them is.

First five minutes

Three prompts that scored 3 of 3, measured in round 21, 2026-09-05. Paste one in as it is written.

Acme Ltd wired us a 500 euro security deposit today, reference SEPA 88213. Please record it.

Paste this into Claude with the server connected.

What it did, measured in round 21, 2026-09-05: One deposit_record {client: Acme Ltd, amount_minor: 50000, currency: EUR, kind: security, reference: SEPA 88213, received_date: 2026-09-05} produced DEP-2026-0001 on the first turn, identical to round 20 stdio.

Apply 300 euro of that deposit against invoice INV-2026-0001.

Paste this into Claude with the server connected.

What it did, measured in round 21, 2026-09-05: One deposit_apply {id: DEP-2026-0001, invoice: INV-2026-0001, amount_minor: 30000}.

Can we use what's left of Acme's deposit against INV-2026-0002?

Paste this into Claude with the server connected.

What it did, measured in round 21, 2026-09-05: The model tried the call rather than reasoning about it.

On the free tier for this path: 5 deposits recorded per calendar month, counted by received date, with applying to invoices, refunds, lists, balances and the text statement all unlimited on every tier: a cap that trapped a client's deposit would be a limit on their money rather than on yours.
