Four servers, one pricing rule: $19 once for a server, $39 once for all of them, lifetime, no subscription and no seat count. The free tier is meant to be the whole product for light use rather than a demo that stops at the interesting part. This page lists the exact limits so you can decide before paying rather than after.
| Server | Free | Pro ($19 once) |
|---|---|---|
| Time Tracker | Unlimited timers and entries. Reports, listings and CSV export cover the last 7 days. 2 projects with an hourly rate. Currency per entry (EUR, USD, GBP, PLN). | Full history, invoice_summary, grouping by tag, unlimited rated projects. |
| Price Tracker | Unlimited price checks with a confidence level. 3 watches, 30 observations each. alerts_pending is free. |
Unlimited watches, full history, refresh every watch at once. |
| Spreadsheet | Every tool. Reads files up to 5 MB and 5,000 rows. Writes up to 500 rows per file; over that nothing is written and the tool says so. | No row or size limits, up to a 50 MB file ceiling. |
| Invoice | 3 invoices per calendar month, small footer line on the PDF. Overdue report free. | Unlimited invoices, no footer, logo, custom invoice number prefix. |
| Bundle | - | $39 once for all four, lifetime. Saves $37 against buying them separately. |
No limit corrupts data or fails silently. Over a spreadsheet read cap, the tool returns the rows it is allowed to return and appends a note saying how many were left out. Over a write cap, nothing at all is written: an earlier version wrote 200 of 400 rows and reported success, which produced a file that looked complete, and that behaviour was removed. Over the time tracker's 7 day window, nothing is deleted; older entries stay on disk and appear the moment a key is activated. Gated tools return one plain message naming the feature, the price and the checkout URL.
After payment you get a key that looks like MCPL1.xxx.yyy. It is an Ed25519 signature over
a small payload: the product, an id, and the issue time. Verification happens locally against a public
key compiled into the server. Two consequences worth stating plainly. The servers never phone home,
because there is nothing to phone home about: no activation server, no license check on startup, no
telemetry, no usage counting. And activation works with the network off, on a plane or on an air-gapped
machine.
Activate it either way:
# In the chat, run the license_activate tool with your key, or:
export MCP_LICENSE_KEY=MCPL1.xxxxxxxx.yyyyyyyy
# Or write it once for every server on this machine:
mkdir -p ~/.config/mcp-servers
printf '{"key":"MCPL1.xxxxxxxx.yyyyyyyy"}' > ~/.config/mcp-servers/license.json
Lookup order is the environment variable, then that config file, then the free tier. The bundle key carries a wildcard product, so one key covers all four servers with the same steps. Every tool ships in the free build; a Pro key removes limits rather than downloading anything.
Checkout is Stripe. The key appears on the success page immediately after payment and no email is sent with it, so save it there. If you lose it, the same page can be reloaded, and support@zovo.one can recover it from the session id printed on your Stripe receipt. Refunds within 14 days, no argument and no form: mail support@zovo.one. Prices are one-time; there is no renewal to cancel and no card on file to remove.
If one server is a daily tool for you, buy that server. If two or more are, the bundle is cheaper than two. The honest guidance: try the free tier for a week first, and buy when a limit gets in your way, because for a light user the free tier is the whole product. See the guides for time tracking, invoices, spreadsheets and price watching.
No. $19 once for one server, $39 once for all four, lifetime. There is no renewal, no seat count and no card kept on file.
No. The key is an Ed25519 signature verified locally against a public key compiled into the server. There is no activation server and no telemetry, so activation and use both work offline.
Nothing is deleted or degraded. Free limits restrict what a tool returns or writes, not what is stored, so activating a key later reveals the whole history that was already on disk.
Yes. The key is a signed file, not a per-device activation. Put it in MCP_LICENSE_KEY or ~/.config/mcp-servers/license.json on each machine you work from.
Mail support@zovo.one within 14 days and the payment is refunded. Because the key cannot be revoked remotely, this runs on trust in both directions.
