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).
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.

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.
