Onboarding Goods Receipt Inspection Runs

mcp-goods-receipt

[theluckystrike/mcp-goods-receipt MCP server]

In the official MCP Registry (io.github.theluckystrike/goods-receipt).

Purchase orders and the goods-receipt notes that receive them. A PO carries a reference, a supplier, and dated lines - sku, description, whole units ordered - plus whole-percent over/under tolerances that decide when a receipt is flagged. A GRN is raised against an open PO, one cell per line: units received, units damaged, and any shortage you already know about. Shortage is derived, not typed - ordered minus received, floored at zero - and shows up as a discrepancy the moment the numbers disagree.

The one rule that decides everything else

Over-tolerance is checked against the cumulative total across every GRN raised on the line, not against each delivery in isolation.

Three deliveries of 40 against an order of 100 at 10% are allowed in ones and tens but the third delivery is refused, because 120 received of 100 ordered breaks the over tolerance even though no single delivery did. Partial deliveries are fine - several GRNs against the same PO is the normal case - and the cumulative rule is what stops them quietly over-receiving.

Two smaller rules follow from it:

• Nothing derived is stored. Shortage and discrepancy are worked out on every call from the PO lines and the GRNs already recorded. Damage is the only thing typed in, because it is the only thing the warehouse actually sees.
• Receiving past tolerance is refused, never clamped. Unless the extra units are declared damaged, a receipt that breaks the over tolerance writes nothing and says why. Damaged units still count for the tolerance check - "it arrived broken" is not a licence to order 100 and receive 130.

The tools

Quick start

po_add  { "reference": "ACME-1001", "supplier": "Acme Trading",          "lines": [ { "sku": "BRK-8", "description": "Bracket, steel", "ordered": 100 } ] }grn_add { "po": "PO-0001",          "lines": [ { "line": "L01", "received": 60 } ] }grn_add { "po": "PO-0001",          "lines": [ { "line": "L01", "received": 35, "damaged": 2 },                     { "line": "L01", "received": 10 } ] }   // refused: 105 > 100 + 10%grn_discrepancy {}                                        // L01 is 5 short of 100

Ids look like PO-0001 and GRN-0001; lines inside a PO are L01, L02, ….

Quick start

{ "tool": "po_add", "args": { "reference": "ACME-1005", "supplier": "Acme Trading",            "lines": [{ "sku": "BRK-01", "description": "Bracket, steel", "ordered": 10 }] } }{ "tool": "grn_add", "args": { "po": "PO-0001", "lines": [{ "line": "L01", "received": 9, "damaged": 1 }] } }{ "tool": "grn_discrepancy", "args": { "po": "PO-0001" } }

A GRN that arrives past the over tolerance is refused; shortage is computed as ordered minus received and shown as a discrepancy. grn_export_csv (Pro) writes the whole ledger out as CSV.

Free vs Pro

The domain is capped estate-wide (2,000 POs, 5,000 GRNs, 200 lines) on every tier - these are hard rules so a store cannot grow past what the file format can hold, not a paywall. Pro unlocks CSV export for pushing receipts into a spreadsheet or an ERP.

Privacy

All data stays local, in ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/goods-receipt/, in store.json (POs and GRNs) and counter.json (the PO- and GRN- series). There is no network call anywhere in this server, no API key, and no account. The only file it reads that it does not own is the shared business profile, and it never writes to it.
