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. Setup and examples: https://datoqa.bhazarstudio.workers.dev/docs/start/ Holiday coverage and calendar export: https://datoqa.bhazarstudio.workers.dev/docs/holidays/ 24 tools in the general edition.

Tideline, a publication of JBPS Capital LLC, publishes the end-of-day state of a rules-based US equity index model (SPY/QQQ) after the US close on trading days. This read-only MCP server lets an AI agent read what Tideline has published. Without a key it provides the public record, shown with a 30-day delay, the fixed vocabulary, and independently timestamped ledger fingerprints (RFC 3161 and OpenTimestamps). With a Tideline Core key, it provides the current published state the evening it is published, including the no-margin line. The server cannot place, route or manage orders and holds no account data. Tideline is an impersonal publication, identical for every subscriber; it is not individualized investment advice.
Check that a package, module or DOI exists before an agent installs, imports or cites it.
Web scraping for agents. Point it at a URL and it returns the page as clean markdown, JavaScript-rendered pages included. Point it at a site and it maps the URLs or crawls the section you need in the background, a few pages at a time so results fit in the conversation. Search the web and read full pages, extract fields with a JSON schema you define (validated, never invented), read a store's catalogue or a blog's posts from the platform's own feed, and check whether a page has changed. Failed requests cost nothing. The free plan includes 1,500 credits a month.
