|---|---|---|
list_sourcesList data sources | List the official statistical sources served by this data layer (e.g. Statistics Canada, FRED), with dataset/series counts, cadence notes, and terms links. Start here to see what exists. | read-only |
search_catalogSearch the series catalog | Find series across ALL sources in one call: case-insensitive search over series ids, indicator names, geographies, and dataset titles (e.g. "unemployment canada", "10-year treasury", "CPI"). Returns candidate series… | read-only |
list_datasetsList datasets in a source | List the datasets (official releases/tables) available in one source, with coverage dates and links to the official table pages. | read-only |
get_seriesGet series metadata + verification | Full metadata for one series: indicator, unit, frequency, geography, coverage, its VERIFICATION STATUS (passing/stale/failing/unverified from golden-value + freshness checks against the live source), recent check… | read-only |
get_observationsGet observations (with provenance) | Observation values for one series. Every value carries provenance (the exact source URL it came from, retrieval time, connector version) and the envelope carries the series verification status + citation. Defaults to… | read-only |
get_series_statsSummary statistics for a series | Latest value, previous, all-time min/max, mean, and change vs the previous period and vs a year ago — computed over the verified store, with the citation attached. The cheap way to answer "what is it now and how has it… | read-only |
create_monitorWatch a series (webhook on movement) | Create a monitor: when the store's refresh lands a new period or a revised value for the series, a series.updated webhook fires to your URL with the new value, verification status, and citation. Requires an API key… | writes |
list_monitorsList your monitors | Monitors on your API key, with delivery health (last fired, failures, active). | read-only |
delete_monitorDelete one of your monitors | writes | |
answerAnswer a question from verified data | The flagship: ask a natural-language question about the served official statistics. Returns a COMPUTED answer (real Python runs in a sandbox over the verified store, nothing is estimated by a model), the Plotly chart,… | writes |
deep_analysisDeep multi-angle analysis from verified data | The moat: a PLANNED multi-section report on a question. The engine designs 3-4 orthogonal analyses (trend, statistics, outliers, cross-series relationships), runs real Python for each in the sandbox over the verified… | writes |
What https://starwell.dev/api/starwell/mcp answered to tools/list, asked without credentials over MCP 2025-11-25. The token figure is the size of the list as sent, divided by four; a model sees about that much before it calls anything. Full definitions, input schemas included, are in the listing's JSON under mcpTools.
