For a small freelance practice or a one-person trade, the answer is the bundle: $39 once for 41 MCP servers that cover the paperwork end to end, run offline, and each has a free tier that does not expire. The accounting servers below are the ones that earn their keep, with the honest limit of each free tier.
MCP Invoice allocates a number that never repeats, computes VAT lines and renders an A4 PDF from one sentence. MCP Quotes prices a quote in chat with VAT and discounts, and the accepted quote turns into the invoice. Together they are the quote to cash loop.
MCP Expense Tracker logs receipts and expenses and attaches a SHA-256 hash of the receipt file as proof. MCP Mileage Log records trips per jurisdiction. The expense entries turn into invoice lines for the invoice server, and the mileage log is the basis for a claim.
MCP Bank Statement categorises a bank CSV export with rules you teach it and reconciles it against your invoices and expenses. MCP Cash Book derives a double-entry ledger from the books you already keep and proves it to the minor unit, and MCP Statement of Account ages what each client owes as at any date. These are the reconciling half of month-end close.
MCP Petty Cash reconciles the cash in the tin against the paperwork, and MCP Deposits holds security and retainer deposits per client and applies them to invoices. Both are genuinely free at the one-tin / five-deposits-a-month scale that a small practice actually runs.
Every server here has a working free tier, and most of them answer at a URL with nothing installed: /mcp/connect mints a free anonymous token and prints a ready URL per server, which you paste into Claude Desktop, Claude.ai or Cursor as a remote server. The free tiers are not demos; several are the real workflow at a small scale (three invoices a month, five open quotes, two bank accounts, one petty cash float).
Bought singly the accounting servers above total more than $39; the bundle is $39 for all 41 servers, one lifetime key that verifies offline with an Ed25519 signature and never expires. The full catalogue is on the home page, each product page states its free tier from the same data the code uses, and free MCP servers for freelancers is the honest guide to what costs nothing at all.
Start with the server for the problem you have today, on its free tier, then add the neighbours as the workflow needs them. The guides index is organised by task, not by product, so it maps a sentence you might say to the server that answers it.
For a small freelance practice the practical answer is the bundle: $39 once for 41 MCP servers covering invoices, quotes, expenses, mileage, bank-statement reconciliation, cash book, statement of account and petty cash, all offline with free tiers that do not expire. Pick the server for the task you have today and add neighbours as the workflow needs them.
Yes. Three invoices a month, five open quotes, two bank accounts with 12 months of transactions, one petty cash float, and so on. The free tiers are the real workflow at a small scale and do not expire.
Most of the servers answer at a URL. /mcp/connect mints a free anonymous token and prints a ready URL per server, which you paste into Claude Desktop, Claude.ai or Cursor as a remote server.
A $19 key unlocks one server. If you need more than two or three of them, the $39 bundle for all 41 is the cheaper path, and one key covers every server.
