bill-of-sale

mcp-bill-of-sale

In the official MCP Registry (io.github.theluckystrike/bill-of-sale). Record a sale and get a signed-paper-ready bill of sale. Tell your assistant who sold, who bought, what the item is, with the VIN, serial number or IMEI where it has one, the price and the date, and the server writes the document: parties, item, price, an as-is clause for second-hand sales, any warranty in your own words, and signature lines for both sides. Work on it as a draft, finalize it into the frozen signing copy, and print it as Markdown or as a single self-contained HTML file that prints to PDF from any browser with no assets beside it. Everything stays on your machine; there is no account and no network call in this server at all.

npm publish for @theluckystrike/mcp-bill-of-sale is pending, so npx -y @theluckystrike/mcp-bill-of-sale returns 404 today. Until then, a clone+build is the working path.

Tools

tool	what it does
sale_create	Record a sale and generate the bill of sale: seller, buyer, item with VIN/serial/IMEI where it has one, price in minor units, date. Returns BOS-YYYY-NNNN. An identical repeat sale is refused unless you confirm it
sale_update	Change anything on a draft before signing: price, parties, item details, identifiers, the as-is clause, warranty, notes. Empty string clears an optional field
sale_finalize	Freeze the draft into the signing copy. From here sale_update refuses it and every render prints without the DRAFT watermark
sale_list	Every bill of sale, newest first: id, status, date, item, buyer, seller, price. Filter to drafts or finalized
sale_get	One bill of sale in full by its BOS number
sale_delete	Delete a draft outright; a finalized document needs confirm_finalized: true. The number is never reissued, so a gap in the series is the record of the deletion
sale_render	Print the document: Markdown, a self-contained HTML file for print-to-PDF, or both, with signature lines. Drafts carry a DRAFT watermark so a review copy cannot be signed by mistake
sale_summary	The book at a glance: draft and finalized counts, total value per currency. Currencies are never added together
license_status / license_activate	Free or Pro, and the key

Free vs Pro

	Free	Pro
Open drafts	10	Unlimited
Finalized documents	5	Unlimited
Render to Markdown and HTML (sale_render)	Unlimited	Unlimited
Read, list and summarize (sale_get, sale_list, sale_summary)	Unlimited	Unlimited
Delete (sale_delete)	Yes	Yes

The document itself is never metered. Whether you hold a signed record of the sale is the question this server exists to answer, and a free tier that withholds the document is a demo. What is metered is the volume of records held: ten open drafts and five finalized documents is a real year of side-business sales, not a trial. sale_delete is free for the same reason the cap is on records held: a draft typed in twice would otherwise cost a slot with no way back but a key.

Get Pro: https://mcp.zovo.one/buy/bill-of-sale, $19 one-time for this server, or $39 for the bundle.

How a sale flows

1. sale_create with the facts. The seller defaults to the shared business profile's name when the profile has one, so the seller block is typed once for the whole suite.
2. sale_render prints the review copy, watermarked DRAFT.
3. sale_update fixes anything the buyer or seller spots.
4. sale_finalize freezes it. sale_render now prints the signing copy: sign the printed page or print the HTML to PDF, and both parties keep a copy.

Every amount is an integer number of minor units, a price is never a float, and dates are checked as real calendar dates. A VIN that is not 17 characters or an IMEI that is not 15 digits is stored as given but flagged in the response, because those are the two identifiers a buyer most often misreads.

Privacy

All data stays local, in ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/bill-of-sale/. Two files: sales.json, counter.json, plus rendered documents under documents/. Nothing is sent anywhere, there is no account, no API key and no network call in this server at all. License keys are verified offline.

The rendered document is a generic template, not legal advice. Bills of sale for vehicles, boats and regulated goods may have statutory form or filing requirements where the sale happens.
