Credit notes against an invoice or standalone: drafts, finalization, rendering and totals, all in integer minor units. You issue a credit note against an invoice or standalone: the recipient, the reason (returned goods, overcharge, discount correction, service issue, other), line items with quantity, unit price and tax rate, and the currency. Every credit note starts as a draft with a CN-DRAFT id no client sees; credit_note_finalize burns the final CN-YYYY-NNNN number in the issue date's year and freezes it, because a finalized credit note is a document the client may have seen, and it can neither be edited nor deleted from there. The counter is written before the record, so a crash burns a number rather than reusing one, and the final series never has a gap. credit_note_render returns Markdown to paste into an email or a self-contained printable HTML page, drafts marked with a DRAFT banner, and credit_note_summary totals what was credited per currency, reason and month.
credit_note_list, credit_note_get, credit_note_render and credit_note_summary are reads and safe to auto-approve. Keep credit_note_finalize behind a click on every tier, because it is the act the client sees, and credit_note_delete is safe: it only ever removes a draft. Nothing here writes into another server's store.
| You say | Tool |
|---|---|
| Issue a credit note to Acme GmbH against INV-2026-0042: two USB-C cables returned unopened, 3 at 24.99 plus one adapter at 9.99, 23% VAT, and refund the 12.00 express shipping. | credit_note_create |
| Render it as Markdown so I can paste it into the email. | credit_note_render |
| What did I credit in March, by reason? | credit_note_summary |
The line math is documented so the printed document reproduces on a calculator: gross is quantity times unit price rounded half-up once, tax is per line rounded half-up on its own base, and the note totals are plain integer sums of the already-rounded line values. On the worked note, 3 x 2,499 at 23% and 1 x 999 at 23% and 1 x 1,200 untaxed give subtotal 9,696, tax 1,954 and total 11,650, and 2.5 x 3,333 rounds half-up to 8,333, never banker's 8,332. The unit suite asserts both.
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: credit-note.mcpb
from the latest release opens as an extension, with no JSON and no terminal.
Cline reads its own config, so here it is:
The config block:
{
"mcpServers": {
"credit-note": {
"command": "node",
"args": ["/absolute/path/to/mcp-servers/servers/credit-note/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/credit-noteThat writes servers/credit-note/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": {
"credit-note": {
"command": "npx",
"args": ["-y", "@theluckystrike/mcp-credit-note"]
}
}
}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 latest release, a clone and build, or the hosted URL.
There is no hosted endpoint for this one yet. MCP Credit Note 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 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: Ten finalized credit notes, lifetime. Drafts, edits, deletion of drafts, listing, reading, rendering and the totals summary are free and unlimited on every tier, because finalizing is the metered act: that is what turns a draft into the document the client sees. Free renders carry a one-line footer. Pro is $19 once, verified offline.
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.
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.
Approve the read-only ones and leave the writing ones behind a click: each entry carries an autoApprove array and a disabled flag.
