Free tier is a word people use to mean anything from a full product to a countdown. Here is the
actual limit for each server, taken from data/facts.json in the repository. No account,
no login, no key: leave MCP_LICENSE_KEY unset and this is what runs.
claude mcp add --scope user time-tracker -- node /absolute/path/to/mcp-servers/servers/time-tracker/dist/index.jsNo key on that line, so the free tier is what starts. license_status on any server
reports which mode it is in if you want it confirmed rather than assumed.
Five tools are never metered, and the reasoning is written into each server's own material.
statement_aging | Who owes me money is the question that server exists for. |
trial_balance | Whether the books add up is the question that server exists for. |
loan_schedule | The payment and the interest are the answer, not the teaser. |
perdiem_calc | The tables are public regulation. Metering the reading of a regulation is charging for the tax authority's work. |
reconcile (petty cash) | Whether the cash matches the paperwork is the whole point of a float. |
The same principle puts contract_value, asset_schedule,
lines_resolve, overdue_report and every zip safety check on the free tier
too.

Look at what is metered. It is nearly always creating a document that goes to somebody else, or holding more records than a one-person business holds. It is almost never reading back what you already put in, and it is never a safety check. Where a cap counts open items rather than items ever created, finishing one frees the slot, which is true on quotes, work orders and change orders.
A byte-identical duplicate is refused before the cap is consulted on several servers, so filing the same thing twice by accident costs you nothing and the refusal names the id already holding it rather than offering an upgrade.
19 dollars once for one server, 39 dollars once for all of them. One-time, not a subscription, and
the key is an Ed25519 signature the server verifies locally with no activation server to phone. Prices
from data/facts.json.
No. There is no clock anywhere in these servers. The free tier is the free tier in month one and in month twelve, and an install with no key never stops working.
The call is refused by name with the reason and the number. Nothing already created becomes unreachable: reads, lists, exports of existing records and every free tool keep working. The cap is on adding, not on reaching what you have.
No. There is no network call in 28 of the 30 servers at all, and the two that make one fetch European Central Bank rates or a product page you named. Counters are local files. Deleting the data folder resets a monthly counter, which is a consequence of not having a server and is stated rather than hidden.
There is no trial key. What there is instead is a free tier designed so the thing each server exists to answer is free: aging, trial balance, loan schedules, per diem calculation and the petty cash reconciliation are all unmetered on purpose. You can judge the answers before you pay for the documents.
