Zovo Recurring Tasks MCP Server

All servers · Buy Pro $19 · All 46 for $39 · Source

Two ways to run it, both free to start. Open mcp.zovo.one/mcp/connect, copy the recurring URL and paste it into any client that takes a URL. It already carries a free token, so there is nothing to install, no account and no header to set. The URL is https://mcp.zovo.one/mcp/recurring/t/<token>. The token is not optional: the bare https://mcp.zovo.one/mcp/recurring connects and lists its tools and then answers every tool call with HTTP 401, so use the link from /mcp/connect or send Authorization: Bearer <token>. Or download recurring.mcpb and double-click it in Claude Desktop.

mcp-recurring

Say "bill Acme 12 hours at 90 EUR on the 1st of every month" once, and stop remembering it. This MCP server stores recurring invoice schedules, client, line items, cadence, start and end dates, and then, when you ask, creates the invoices that have actually fallen due as real records in the invoice server, with its number series, its clients and its A4 PDF. Generation is idempotent: one invoice per schedule per period, keyed by the occurrence date, so running the billing run twice on the same day creates nothing the second time. It also answers "what falls due in the next 30 days" and "what will I invoice per month for the next year". Everything is stored in plain JSON files on your own machine; nothing is uploaded anywhere.

In the official MCP Registry (io.github.theluckystrike/recurring-invoice-scheduler-subscription-billing-due-reminders).

Define a repeating invoice once, generate the due PDFs from chat, no billing SaaS required.

60-second install

npm publish for @theluckystrike/mcp-recurring is pending. Until then, the .mcpb one-click bundle or a clone+build is the working path, both are verified below.

One-click (.mcpb): download recurring.mcpb from the latest release and double-click it in Claude Desktop: https://github.com/theluckystrike/mcp-servers/releases/latest

(claude_desktop_config.json):

{
  "mcpServers": {
    "recurring": {
      "command": "npx",
      "args": ["-y", "@theluckystrike/mcp-recurring"]
    }
  }
}

Claude Code:

claude mcp add recurring -- npx -y @theluckystrike/mcp-recurring

(.cursor/mcp.json):

{
  "mcpServers": {
    "recurring": {
      "command": "npx",
      "args": ["-y", "@theluckystrike/mcp-recurring"]
    }
  }
}

The npx form above starts working the moment the package is published. Until then, use the.mcpb bundle above, or build from source with exactly these three commands:

git clone https://github.com/theluckystrike/mcp-servers.git && cd mcp-servers
npm install
npm run build -w packages/mcp-license -w servers/invoice -w servers/recurring

Then point your client's command at node with one arg: the absolute path to servers/recurring/dist/index.js.

To run in Pro mode set MCP_LICENSE_KEY in the same config block, or call license_activate once with your key.

Pairs with

• mcp-invoice, required in practice, not by code. This server writes into the invoice server's data directory and shares its number counter, its client list and its business profile, so every generated invoice appears in invoice_list, counts in overdue_report and can be re-rendered with invoice_pdf. Set your issuer details once with business_set there; this server has no business_set of its own on purpose, so there is only one profile to keep right.
• mcp-time-tracker, for the hours that are not on a retainer. Track them, invoice them ad hoc, and leave the fixed monthly part to a schedule here.
• mcp-expense-tracker, rebillable costs that change every month belong on an ad hoc invoice; a schedule is for the amount that does not change.

Tools

Tool	What it does
schedule_create	Define a repeating invoice: client, items, cadence, start date, optional end date, due days, notes
schedule_list	Every schedule with cadence, amount per period, next due date and status
schedule_get	Full record for one schedule, plus how many invoices it has generated
schedule_update	Change client, items, currency, cadence, dates, due days or notes. Periods already invoiced are never re-issued
schedule_pause	Stop generating without deleting; history is kept
schedule_resume	Make it active again. Periods that fell due while paused are still due
schedule_delete	Remove the schedule. Invoices it made stay in the invoice server and its history is kept as an audit trail. A re-created schedule gets a new id, so invoice_generate_due warns when it re-covers a period the old one already billed
schedule_skip	Skip ONE occurrence for good, without pausing the schedule -- the answer to "do not bill this client for October". undo: true puts the period back
schedule_upcoming	What falls due in the next N days, with amounts and totals per currency, plus any period that already fell due and was never invoiced. Free covers 30 days
invoice_generate_due	Create the invoices that are due as of a date and render their PDFs. Idempotent, keyed by period; reports created and skipped. At most 60 invoices per call, oldest period first, and it says how many are still due. dry_run shows the run first. Free and unlimited
schedule_history	Pro: the audit log for one schedule -- every period, invoice number, dates, amount, paid status and PDF path
forecast	Expected revenue per calendar month per currency, with paused schedules listed separately rather than dropped. Free covers 3 months
license_status	Show free or Pro mode
license_activate	Activate a Pro key (verified offline)

Resource: recurring://upcoming returns the next 30 days of occurrences as JSON. Prompt: monthly_billing_run, dry run, generate, list what is coming, then report who needs a payment reminder.

Worked example

You: Bill Acme 12 hours at 90 EUR a month, starting 1 June, 14 day terms.

  schedule_create {
    client: "Acme Retainer", currency: "EUR", every: "monthly",
    start_date: "2026-06-01", due_days: 14,
    items: [{ description: "Retainer hours", quantity: 12, unit_price: 90 }]
  }
  -> schedule 9f2c1a04, next dates 2026-06-01, 2026-07-01, 2026-08-01, 2026-09-01

You (on 3 September): Run the billing.

  invoice_generate_due {}
  -> as_of 2026-09-03: created 4 invoices, skipped 0 already invoiced.
     INV-2026-0001  Acme Retainer  period 2026-06-01  EUR 1080.00  due 2026-06-15  .../pdf/INV-2026-0001.pdf
     INV-2026-0002  Acme Retainer  period 2026-07-01  EUR 1080.00  due 2026-07-15  .../pdf/INV-2026-0002.pdf
     INV-2026-0003  Acme Retainer  period 2026-08-01  EUR 1080.00  due 2026-08-15  .../pdf/INV-2026-0003.pdf
     INV-2026-0004  Acme Retainer  period 2026-09-01  EUR 1080.00  due 2026-09-15  .../pdf/INV-2026-0004.pdf
     Total: EUR 4320.00

You (five minutes later, having forgotten): Run the billing.

  invoice_generate_due {}
  -> as_of 2026-09-03: created 0 invoices, skipped 4 already invoiced.

The second run is the point: the period, not the calendar day, is the key, so a repeated billing run is a no-op rather than a duplicate invoice sitting in a client's inbox.

Dates: what happens at a month end

Every date is a local ISO calendar date, YYYY-MM-DD. An occurrence is the k-th step from start_date, and occurrence 0 is start_date itself, so a schedule starting today is due today.

• weekly = +7 days per step. {days: n} = +n days per step.
• monthly = +1 month, quarterly = +3 months, yearly = +12 months.
• Month ends. The month step keeps the day of month of start_date and clamps it to the length of the target month; it never carries the clamp forward. From 2026-01-31 the series is 01-31, 02-28, 03-31, 04-30, 05-31, February does not silently turn a month-end retainer into a 28th-of-the-month retainer.
• Feb 29. The same rule makes a yearly schedule starting 2028-02-29 fall on 02-28 in common years and back on 02-29 in the next leap year.
• anchor_day / end_of_month (Pro). anchor_day replaces the day of month before clamping, so anchor_day: 31 means the last day of every month; end_of_month: true does the same explicitly. Both are ignored for weekly and {days: n}, which have no month to anchor to. An anchored first occurrence that would land before start_date is dropped, never billed early.
• end_date is inclusive. An occurrence landing exactly on end_date is generated; the next one is not.
• Long-lived schedules. Looking up what is due does not replay the schedule from start_date: it jumps to an estimate near the date you asked about and scans forward from there, so a daily schedule created in 2010 still reports what is due in 2026 instead of exhausting its per-run occurrence cap walking there one day at a time.

Money

Amounts are held as integer minor units by the invoice engine, the same ISO 4217 table, the same round-per-line-then-sum contract, so a schedule's amount and the invoice it produces can never disagree. Each line's gross is rounded first, tax is computed and rounded per line and grouped into one line per rate, and the totals are integer sums of those already-rounded values. A schedule bills in its own currency, or your business default currency if it has none; nothing here converts between currencies.

How it stores data

Schedules and the generation log live in ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/recurring/ as schedules.json and history.json. The go into the invoice server's directory, ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/invoice/, with their PDFs under its pdf/ subfolder, the same files invoice_list, overdue_report and invoice_pdf read there.

Every mutation runs under an advisory lock file. Anything that writes an invoice takes two locks, always in the same order, recurring/.lock first, then invoice/.lock, so two billing runs (or a billing run and a hand-written invoice in the other server) cannot interleave, cannot allocate the same invoice number and cannot deadlock. Invoice numbers are allocated inside the lock; the PDFs are rendered after it is released, so a slow render never holds up the counter. Saves go to a temporary file and are renamed into place.

If schedules.json or history.json is unreadable or not valid JSON it is never treated as "empty": the file is moved aside byte-for-byte as <name>.json.corrupt-<timestamp>, a <name>.json.corrupt marker is written, and every tool fails loudly until you restore a good copy and delete the marker. This matters more here than anywhere else in the collection: a history.json silently read as empty would re-bill every period the schedule has ever covered.

Limits and honest caveats

• Nothing runs in the background. This is a stdio MCP server: it exists while your client runs it. No daemon, no cron, no email. Invoices are created when you (or the monthly_billing_run prompt) call invoice_generate_due. auto_generate is a marker for that prompt, not a scheduler.
• Nothing is sent to the client. The server produces the invoice record and the PDF; delivering it and chasing payment is still yours to do. overdue_report in the invoice server tells you who to chase.
• Free tier allows 3 active schedules. Pausing one frees a slot; the paused schedule's history is kept.
• Deleting a schedule keeps its history rows, deliberately: a re-created schedule with the same id cannot double-bill a period. Invoices already generated are never touched by anything here.
• schedule_update changes future periods only. A period already invoiced keeps the amount that was billed; correct it in the invoice server instead.
• No proration and no mid-period cancellation credit: a period is billed in full or not at all.
• No currency conversion; a schedule bills in one currency.

Troubleshooting

• npx hangs or fails to find the package: npm publish for this package is pending. Use the .mcpb bundle or the clone-and-build path above until it lands.
• Using the clone path: build servers/invoice before servers/recurring, the engine is imported from it. npm run build -w packages/mcp-license -w servers/invoice -w servers/recurring does that in order.
• "No business profile yet": run business_set in the invoice server (mcp-invoice), not here. Generation is never blocked by it; the PDF just carries the placeholder issuer "Your business".
• The invoices are not in my invoice server: both servers must see the same XDG_DATA_HOME. They write to .../mcp-servers/invoice/ under it; if one client sets that variable and the other does not, you have two stores.
• A period was skipped: invoice_generate_due only skips a period already present in history.json. schedule_history (Pro) or the file itself shows exactly which invoice covered it.
• Node version: requires Node >= 18. Check with node -v.

Privacy

All data stays local: schedules, the generation log, invoices and PDFs are plain files under your own home directory. The server makes no network calls at all, and license keys are verified offline.

Built by theluckystrike. MIT. Support: support@zovo.one

One business profile for the whole suite

Your identity is stored once, at ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/profile/business.json, and every server in the suite reads it: the invoice issuer, the docx letterhead, the recurring issuer, expense-tracker's default VAT rate, time-tracker's and timezone's home zone, and the resume and contract letterheads. Set it once with business_set (invoice or docx) - you never repeat it anywhere else. An email address is only ever taken from that profile or from an explicit argument; when none is stored, documents show [add: email] and the tool says so rather than letting anyone improvise an address.

First five minutes

Two prompts that scored 3 of 3, measured in round 15, 2026-09-04. Paste one in as it is written.

Do a dry run so I can see what would be invoiced right now before anything is created.

Paste this into Claude with the server connected.

What it did, measured in round 15, 2026-09-04: One occurrence, period 2026-09-01, still_due_after_this_run 0, and the sentence that makes a dry run safe to trust: nothing was created, and the real run is idempotent, keyed by the occurrence date.

Looks right. Run it for real and give me the invoice.

Paste this into Claude with the server connected.

What it did, measured in round 15, 2026-09-04: INV-2026-0001 Beta Corp period 2026-09-01 EUR 1845.00 due 2026-09-15 plus a link, and it said the invoices land in the store /mcp/invoice reads.
