tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
perdiem_ratesList a scheme's bundled daily allowance rates with the authority, instrument, source URL and effective date they came from. Filter by country or city. Free and unlimited.
schemestringcountrystringcitystringperdiem_calcCalculate the daily travel allowance for one trip: the amount per day and the total in the scheme's currency, with the partial-day fraction and the meal deductions the scheme's own rule applies. Free and unlimited.

An identical record is refused and named, spending no slot. Free: 5 trips a calendar month.

Filter by scheme, destination, traveller, project and start date range. Free and unlimited.
schemestringdestinationstringtravellerstringprojectstringfromstringtostringtrip_deleteDelete one saved trip and free the free-tier slot it held that month. A trip that has been exported or has an expense booked against it is refused with the blocker named, and nothing is written. Free and unlimited.
tripstringrequiredtrip_exportReturn the exact expense_add arguments for a saved trip: one payload for subsistence and, with split_lodging, one for lodging. It writes nothing in the expense-tracker server; only mark_exported changes this trip. Pro.
tripstringrequiredcategorystringbillablebooleansplit_lodgingbooleanmark_exportedbooleanperdiem_reportTotal saved trips per scheme and calendar month, bucketed by start date: trips, days, subsistence and lodging, each in the scheme's own currency, with the trip ids behind every figure. Pro.
fromstringtostringschemestringtravellerstringlicense_statusReport this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
license_activateTurn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
keystringrequiredEach block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.
