Which MCP Server Should You Choose?
B
Choose Bill of sale when:
You need dedicated capabilities in the Legal domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
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
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Bill of sale is categorized under Legal and uses a local stdio subprocess. In contrast, License Verify MCP belongs to Legal using local stdio subprocess. Select Bill of sale when you need capabilities focused on legal and License Verify MCP when you require tools for legal.
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
