MCP Three-Way Invoice Match in Cline

Compare supplier invoice lines with purchase orders and accepted receipt quantities by exact SKU. Pass a structured PO, dated receipt notes, one invoice and an explicit prior_invoiced array. Every exception shows the ordered, accepted, previously billed and currently billed quantities alongside the PO and invoice unit prices. Money uses integer minor units and quantities use whole units. The server does not read PDFs, query an ERP, infer past bills or approve payment.

Preview calls write nothing when save is false. Saving creates a local report; report_delete removes the named saved report, while report_export_csv returns its exception evidence.

What you get in Cline

You say	Tool
Check PO A10/B10 at 100 minor units each against accepted receipts A5/B15 and invoice A10/B10. Prior invoiced is empty: find the hidden SKU mismatch.	`three_way_match`
Now invoice only A5/B10 against the same order and receipts; explain any over-receipt still reported on B.	`three_way_match`
Save this exception report and export its CSV for review.	`report_export_csv`

The offsetting-SKU example and partial-delivery acceptance case are documented in the server README and tests.

Install it in Cline

The file is mcp.json, and the key inside it is mcpServers.

Scope	Path
Cline CLI	`~/.cline/mcp.json`
The editor extension	`opened from the Cline panel, not by path; the documentation deliberately calls it the MCP settings JSON used by the extension`

If you also run Claude Desktop, the shortest path there is one click: three-way-match.mcpb from the bundle catalog opens as an extension, with no JSON and no terminal. Cline reads its own config, so here it is:

The config block:

{
  "mcpServers": {
    "three-way-match": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-servers/servers/three-way-match/dist/index.js"],
      "disabled": false,
      "autoApprove": []
    }
  }
}

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/three-way-match

That writes servers/three-way-match/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": {
    "three-way-match": {
      "command": "npx",
      "args": ["-y", "@theluckystrike/mcp-three-way-match"]
    }
  }
}

No full-app restart. The MCP settings actions include restarting an unresponsive server if its tools do not appear.

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, or the hosted URL.

No install: the hosted endpoint

There is no hosted endpoint for this one yet. MCP Three-Way Invoice Match 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.

Cline notes worth knowing first

Cline is the one client here with an unsafe transport default. `type` selects it, and omitting `type` falls back to the legacy sse transport, so a streamable HTTP endpoint needs it written in or you will debug a server that is fine. Local entries carry "disabled" and an "autoApprove" array.

Free: Every full preview up to 500 PO/invoice lines, free pages of large reports, three simultaneous saved reports, retrieval, deletion and CSV export. Pro is $19 once, verified offline.

Questions

Where does the config live?

The CLI reads ~/.cline/mcp.json. For the extension, do not hunt for a path: MCP Servers icon, Configure tab, Configure MCP Servers. cline mcp opens a wizard, and cline config mcp --json is the non-interactive form.

The hosted endpoint will not connect.

Set the transport explicitly. Omitting type falls back to the legacy sse transport, so streamable HTTP needs "type": "streamableHttp" written in. It is the one default here that sends you debugging a server that works.

Should I auto-approve MCP Three-Way Invoice Match's tools?

Approve the read-only ones and leave the writing ones behind a click: each entry carries an autoApprove array and a disabled flag.
