Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Starwell: World Data & Statistics MCP server?
Starwell: World Data & Statistics is a hosted endpoint at https://starwell.dev/api/starwell/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
answer Answer a question from verified data ~287
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, the Python code, citations to the official tables, and a verification badge per series. CROSS-SOURCE: one question may join series from DIFFERENT agencies, e.g. unemployment from the US BLS, Statistics Canada and the UK ONS in a single call, for correlations, ratios, and like-for-like comparison. How many series one question may join is set by the caller's plan; asking for more returns a series_limit error naming that cap. Returns a refusal when no served series can answer. Takes 10-40 seconds. Requires a free API key (create at /account on the Starwell host; pass Authorization: Bearer dlk_... or set STARWELL_API_KEY on the starwell-mcp bridge). Keyless calls return key_required.
| Name | Type | Req | Description |
|---|---|---|---|
| end | string | – | YYYY-MM-DD |
| question | string | yes | – |
| series | array | – | Optional: pin exact series, across sources, and skip AI resolution |
| share | boolean | – | When true, the answer becomes a permanent public page and meta.permalink carries its URL — hand it to the user as a citable link |
| start | string | – | YYYY-MM-DD |
No output schema declared.
No examples provided.
create_monitor Watch a series (webhook on movement) ~123
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 (free with an account at /account); webhook must be https. Manage with list_monitors / delete_monitor.
| Name | Type | Req | Description |
|---|---|---|---|
| seriesId | string | yes | Series id, e.g. 'DGS10' |
| source | string | yes | Source slug, e.g. 'fred' |
| webhookUrl | string | yes | https URL to receive series.updated events |
No output schema declared.
No examples provided.
deep_analysis Deep multi-angle analysis from verified data ~247
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 store, and synthesizes one decision-ready report. Every number computed, every series cited and verification-badged. Sections can join series from DIFFERENT agencies in one report, up to the caller's plan width; over it, the call returns a series_limit error naming that cap. Slower than answer (60-180 seconds), so use it for "analyze", "break down", "give me a full picture" asks; use the answer tool for a single direct question. Requires a free API key (create at /account on the Starwell host; pass Authorization: Bearer dlk_... or set STARWELL_API_KEY on the starwell-mcp bridge). Keyless calls return key_required.
| Name | Type | Req | Description |
|---|---|---|---|
| end | string | – | YYYY-MM-DD |
| question | string | yes | – |
| series | array | – | Optional: pin exact series, across sources, and skip AI resolution |
| start | string | – | YYYY-MM-DD |
No output schema declared.
No examples provided.
delete_monitor Delete one of your monitors ~18
No description provided.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Monitor id from list_monitors |
No output schema declared.
No examples provided.
get_observations Get observations (with provenance) ~212
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 the latest 60 points; use start/end (YYYY-MM-DD) or latest to control the window. Pass asOf for a point-in-time read: the values as Starwell's store held them on that date, before any later revision (available from the series' first ingest forward).
| Name | Type | Req | Description |
|---|---|---|---|
| asOf | string | – | Point-in-time cutoff, YYYY-MM-DD (end of that UTC day) or an ISO 8601 instant: return what Starwell's store held then, ignoring later revisions |
| end | string | – | YYYY-MM-DD inclusive upper bound |
| latest | integer | – | Return only the latest N points (default 60 when no start/end given) |
| seriesId | string | yes | – |
| source | string | yes | – |
| start | string | – | YYYY-MM-DD inclusive lower bound |
No output schema declared.
No examples provided.
get_series Get series metadata + verification ~100
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 records, and the citation to the official table.
| Name | Type | Req | Description |
|---|---|---|---|
| seriesId | string | yes | Source-native series id, e.g. 'UNRATE' or 'v41690973' |
| source | string | yes | Source slug, e.g. 'fred' |
No output schema declared.
No examples provided.
get_series_stats Summary statistics for a series ~99
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 moved" without a full analysis run.
| Name | Type | Req | Description |
|---|---|---|---|
| seriesId | string | yes | Series id, e.g. 'DGS10' |
| source | string | yes | Source slug, e.g. 'fred' |
No output schema declared.
No examples provided.
list_datasets List datasets in a source ~54
List the datasets (official releases/tables) available in one source, with coverage dates and links to the official table pages.
| Name | Type | Req | Description |
|---|---|---|---|
| source | string | yes | Source slug, e.g. 'fred' or 'statcan' |
No output schema declared.
No examples provided.
list_monitors List your monitors ~27
Monitors on your API key, with delivery health (last fired, failures, active).
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_sources List data sources ~48
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_catalog Search the series catalog ~198
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 with units, coverage, verification status, and license, plus datasetMatches from the wider dataset index — datasets whose series can be requested by source-native id and are fetched from the official source on first call. The fastest path from a question to the exact series id to fetch or pin in the answer tool.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max results (default 20) |
| offset | integer | – | Skip the first N ranked hits (default 0). When hasMore is true, call again with offset = offset + limit. |
| query | string | yes | Search terms, e.g. "unemployment rate canada" |
| source | string | – | Optional source slug to restrict to, e.g. 'fred' |
No output schema declared.
