Sovereignty Monitor public endpoint

Read-only JSON over the European Sovereignty Monitor data: the daily record of news and voices across four areas, the European Sovereignty Index (where Europe stands against twenty measurements, and which way the news moved), the stack map, the sovereign-euro ledger, Horizon Europe grants from CORDIS, and the regulation timeline. No login. The data is published under CC BY 4.0; grants data comes from CORDIS, European Union.

Every item on the Sovereignty Monitor is graded Verified or Reported, states what it does not test, and is corrected in the open with the original quoted.
Horizon Europe money is contracted, not disbursed; a grant is not a product; consortium co-membership is not partnership.
The ledger records where the sovereign euro lands, under named tests; a case passing one test can fail another.
An item naming an actor is not evidence that the actor acted, and two actors on one item are not partners.

Collections: news, cards, layers, partners, goals, variants, tests, cases, contradictions, consortia, orgs, events, actors. Any query parameter other than limit filters a collection by that field (case-insensitive; list fields match by inclusion). Unknown ids come back as 404 with suggestions.

MCP for Claude and other assistants

Add https://api.sovereigntymonitor.eu/mcp as a custom connector (no authentication). It speaks Streamable HTTP with JSON responses and exposes thirteen tools: sovmon_status, sovmon_news, sovmon_news_stats, sovmon_item, sovmon_voices, sovmon_actor, sovmon_calendar, sovmon_insights, sovmon_index, sovmon_get, sovmon_list, sovmon_search, sovmon_card_context.

Source data

The endpoint reads the nine published files, news.json, index.json, voices.json, stack.json, flows.json, cordis.json, timeline.json, actors.json and calendar.json, written by the publisher at every publish (the site ships the same files), and caches them for ten minutes. Each is one flat JSON file, small enough to load whole into a notebook or a dashboard; fields are added over time, never renamed. Sourcing rules and the grading are on the method page. Machine-readable: llms.txt, openapi.json. Corrections welcome, with a primary source.
