GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Free MCP tools for historical exchange rates, country economic indicators and international public-holiday calendars. No account, API key or wallet required for factual tools during the pilot. Holiday coverage combines direct government calendars for France, the United Kingdom and Hong Kong with the international OpenHolidays curated collection. Available countries and years vary: consult list_holiday_regions for current coverage. Preserve national/regional scope, multilingual names, source dates, substitute-day notes and half-day flags. Coverage is not exhaustive worldwide; future dates may change and per-event government confirmation is unavailable for OpenHolidays. Try: the ECB USD-per-EUR reference rate on 2008-09-15; US GDP per capita in current USD for 2000 and 2020; or nationwide German public holidays for 2027 (region oh-de, year 2027, nationwide_only true). Calendar export is available in iCalendar/ICS through the HTTP API. Responses include source citations, observation dates, units, freshness, evidence links and explicit gaps. ECB rates are not live tradable quotes; economic series have publication delays and missing values. Source/schema checks are not independent factual verification. Public pilot without an SLA.
