Review supplied invoice history for repeated references, formatting variations and equal amount/date candidates. Pass 1–1000 structured records, each with exact entity and supplier IDs, document type, reference, date, currency and positive integer minor-unit total. Three independent equality rules retain original records and overlapping reasons. A candidate is a review prompt, not a confirmed duplicate or payment decision. No ERP, PDF extraction or implicit stored history.
Keep exact entity and supplier IDs from the source. Similar display names do not merge comparison scopes, and leading zeros stay meaningful in invoice numbers.
| You say | Tool |
|---|---|
| Review INV-001 and inv /001 from the same supplier and entity; retain INV-1 as a distinct leading-zero reference. | duplicate_invoice_check |
| Show the same reference even when its amount and invoice date differ, keeping both original values. | duplicate_invoice_check |
| Save the review and export the complete source records and candidate reasons as CSV. | report_export_csv |
Frozen operator round 46 checks five buyer tasks through actual local MCP stdio calls. These are synthetic operator tests, not customer research.
The file is .cursor/mcp.json, and the key inside it is mcpServers.
| Scope | Path |
|---|---|
| This project only | <project>/.cursor/mcp.json |
| Every project | ~/.cursor/mcp.json |
If you also run Claude Desktop, the shortest path there is one click: duplicate-invoice-check.mcpb
from the bundle catalog opens as an extension, with no JSON and no terminal.
Cursor reads its own config, so here it is:
The config block:
{
"mcpServers": {
"duplicate-invoice-check": {
"type": "stdio",
"command": "node",
"args": ["/absolute/path/to/mcp-servers/servers/duplicate-invoice-check/dist/index.js"]
}
}
}The node command above wants a built file. From a clone, once:
git clone https://github.com/theluckystrike/mcp-servers.git
cd mcp-servers && npm install
npm run build -w packages/mcp-license -w servers/duplicate-invoice-checkThat writes servers/duplicate-invoice-check/dist/index.js, and its absolute path is the one argument
the config needs.
The npm packages are not published yet, so the form below returns a 404 today. It is here because it is what the entry becomes the day the publish lands, with nothing else changed:
{
"mcpServers": {
"duplicate-invoice-check": {
"command": "npx",
"args": ["-y", "@theluckystrike/mcp-duplicate-invoice-check"]
}
}
}The Customize page shows the server and its tools once it has started.
Nothing is published to npm yet, so the working install paths are the ones above: the .mcpb bundle from the bundle catalog, a clone and build.
There is no hosted endpoint for this one yet. MCP Duplicate Supplier Invoice Check runs locally over stdio with the config above, which is also the only form in which it reads and writes files on your own disk. Thirty of the servers in this collection are served at https://mcp.zovo.one/mcp/<name> over MCP streamable HTTP; https://mcp.zovo.one/mcp/connect lists them and prints a ready URL for each.
The current field table marks `type` as required, with `stdio` for a locally launched server, so write it out rather than relying on command and args alone. The other documented restriction is that `envFile` is stdio-only: a remote HTTP or SSE server does not read it, and its headers belong in the config.
Free: Every diagnostic up to 1000 records, complete free evidence pages, CSV and three concurrent saved reports. Pro is $19 once, verified offline.
<project>/.cursor/mcp.json applies to that project and can be committed, which suits a server tied to one client. ~/.cursor/mcp.json applies everywhere. Both are managed from the Customize page.
The current field table marks type as required, with stdio for a locally launched server, so include it. Pointing at a remote endpoint, envFile is documented as stdio-only and is not read.
Servers in Cursor's marketplace get an Add to Cursor button. The deeplink reference currently documents prompt, command and rule links only, so for MCP Duplicate Supplier Invoice Check pasting the config block above is the supported route.
