bug(worldbank_get_data): out-of-range date_range is dropped and the full series returned
Server version

Runtime
Bun
Runtime version
Bun 1.3.14
Transport
HTTP (Streamable HTTP)
Description
When a date_range span does not overlap the indicator's coverage, the World Bank API ignores the date parameter and returns the entire series. worldbank_get_data passes that response through as a successful match, so a request for 1850–1900 comes back with 2021–2025 observations and no indication the filter was discarded.…

bug(worldbank_search_indicators): keyword query returns the unfiltered catalog

Bun
Runtime version
Bun 1.3.14
Transport
HTTP (Streamable HTTP)
Description
worldbank_search_indicators sends searchterm to the World Bank /indicator endpoint for keyword-only searches, but the upstream endpoint returns the full catalog instead of filtering. The tool passes that response through as if it matched the query, so both ordinary and impossible searches return unrelated indicators.

bug(indicators): upstream HTTP 404 on escaped IDs surfaces as a raw fetch failure
Server version

^0.12.8
Runtime
Bun
Runtime version
1.4.0
Transport
HTTP (Streamable HTTP)
Description
An indicator or topic ID containing a character that encodeURIComponent escapes (/, %) makes the World Bank API answer a real HTTP 404 instead of its usual HTTP-200 invalid-value envelope. The service only recognizes the envelope, so the 404 escapes as the framework's raw FetchHttpError: a -32001 error whose message is…

feat(worldbank_get_poverty): expose PPP vintage and survey comparability
Use case
worldbank_get_poverty cannot select or report the PPP vintage/data release used for a poverty estimate, and it drops the provider's survey-comparability fields. A poverty-trend or cross-country comparison needs both: the PPP vintage to know which dollars a headcount or poverty line is expressed in, and the comparability fields to know whether two survey years can be compared at all.
Proposed behavior
Extend the existing tool with an optional PPP-vintage selector and return…

Description
Indicator descriptions pass provider HTML through as prose on both MCP surfaces. Break markup is left embedded in run-on text instead of preserving the intended structure.

bug(worldbank_search_indicators): punctuation-only queries return unfiltered results

worldbank_search_indicators treats a punctuation-only keyword as a match for every indicator, while echoing the keyword as an applied search. This is a remaining unfiltered-success path after keyword matching moved into the service.

Description
worldbank_search_projects validates the shape of approved_from/approved_to (CALENDAR_DATE = /^\d{4}-\d{2}-\d{2}$/ in worldbank-search-projects.tool.ts) but not whether they are real calendar dates or an ordered interval.

Description
The allowed page sizes for worldbank_search_projects and worldbank_get_poverty produce responses large enough to exceed common client context limits. Neither tool's per_page ceiling (1000, in both schemas) is bounded by the serialized payload size, and neither has an output budget or truncation-disclosure mechanism —…

Description
worldbank_get_data misreports totalCount/totalPages on an exhausted page whenever the requested date_range was dropped by upstream — WorldBankApiService.getData() returns early on an empty upstream page (src/services/worldbank/worldbank-service.ts:821-833) before the local date-window filter ever runs, so the response…

The single-country and single-indicator lookups accept World Bank collection selectors and silently choose one returned record. Their matching resources have the same behavior. Invalid input therefore produces plausible metadata for an arbitrary item rather than an error.

feat(worldbank_get_data): serve message-id-175 indicators via the source-scoped data API
Use case
worldbank_search_indicators returns indicators catalogued only under source 57 ("WDI Database Archives"), such as SM.POP.REFG.OR (Refugee population by country or territory of origin), but worldbank_get_data cannot fetch any of them. The standard data endpoint rejects them with message id 175 ("The indicator was not found. It may have been deleted or archived."), with or without source=57. As #24 established, message id 175 is not specific to source 57 — it covers every…

Use case
worldbank_get_data's countries string accepts a single code or "all", but a comma-separated list — "US,JP,KR" — passes schema validation, reaches the World Bank Indicators API verbatim, and the API rejects it with a generic The provided parameter value is not valid error, surfaced to the caller as country_not_found even though every code is valid. worldbank_get_poverty and worldbank_search_projects already accept comma-separated strings; an agent that picks up the…
