Stable logical MCP tool names are taxcompare and berechne, also shown as Obolus.taxcompare and Obolus.berechne in titles and metadata. Do not treat transient link_... resource paths as stable tool identities; if a transient link path is unavailable after an app refresh, rediscover tools and call the same stable logical tool name. Tool routing: if the user asks for one salary across multiple countries, always use taxcompare first. Select taxcompare when the user provides one salary or income amount, two or more countries, and wants tax, net salary, deductions, take-home pay, ranking, or 'where do I keep more money' results. Do not use berechne repeatedly for simple multi-country comparisons unless taxcompare cannot accept the required inputs. Use berechne only when countries.length === 1 or the user provides detailed country-specific payroll assumptions such as tax class, province/state, health insurance, church tax, pension exemption, deductions, benefits, or other payroll details that taxcompare does not support. For berechne, use the declared Obolus field names exactly. LZZ maps to 1=year, 2=month, 3=week, 4=day; Gehalt_ct and other monetary inputs are minor units for that selected payroll period. berechne is country-polymorphic: first choose the meaning from Land, then interpret inputs and outputs. The same fields span DE, AT, CH, US, UK, IE, CA, and AU, but meanings are country-specific: Steuerklasse can mean German tax class, Swiss tariff, US filing status, UK tax code, Irish marital status, or Australian residency class; Bundesland can mean state, canton, province, or UK region; PreTax_Deduction_ct can mean 401k/IRA, RRSP, salary sacrifice, super sacrifice, pension contribution, or similar country deduction. berechne outputs are also country-polymorphic: stable codes such as ST, LSTLZZ, RSV, KSV, PSV, ASV, and VTL must be interpreted with the original request Land rather than as one global tax vocabulary. For "Germany, normal employee, tax class I", use de_payroll_preset=DE_STANDARD_EMPLOYEE_STATUTORY, de_statutory_pension_and_unemployment=true, de_statutory_health_and_care=true, de_health_extra_contribution_percent=2.5, Kirche=0, KinderPVA=0, and Bundesland as full names such as Berlin rather than ISO abbreviations. Never fill raw German Obolus flags such as gesetzliche_RV, gesetzlicheKvPvStatus, KV_Art, or KVZ in normal ChatGPT calls; they are internal compatibility flags and can be valid in product/API payloads for pensioners, civil servants, pension-exempt workers, private health insurance, and other non-standard cases. Advisory warnings are hints, not hard failures, for berechne raw payroll combinations. For taxcompare, prefer salary_ct in minor units plus currency in normal ISO form such as EUR; example: compare EUR 50,000 in US, IE, DE, CA => salary_ct=5000000, currency=EUR, period=annual, tax_year=2026, countries=[US,IE,DE,CA], gross_mode=shared_gross. Use local_median_gross for country-specific median salary benchmarks. taxcompare outputs annual major-currency gross/net/tax/social contribution/total deduction estimates plus ranking_by_net. Tools return structured calculation results for the Obolus result panel and may record private operational access logs.
