v0.6.0: OBS_FLAG/CONF_STATUS split, confidential-slice no_results fix

OBS_FLAG/CONF_STATUS split, confidential-slice no_results fix

• Breaking: eurostat_query_dataset's observations[].status carries only OBS_FLAG now; confidentiality moves to a new confStatus field, and the staged dataframe table gains matching conf_status/conf_status_label columns (#35)
• Fixed: a dataset slice where every cell is confidential no longer wrongly raises no_results (#36)
• OBS_FLAG/CONF_STATUS dictionaries and measure column names consolidated into a shared eurostat-codelists module; both dataframe tool descriptions updated to match

CHANGELOG v0.6.0

v0.5.0: SDMX TSV bulk downloads

SDMX TSV bulk downloads

• eurostat_download_dataset streams the SDMX 2.1 TSV bulk endpoint and stages a whole dataset on the dataframe canvas — roughly half the bytes of eurostat_query_dataset's JSON-stat body for the same data (#8)
• New EurostatBulkService: streaming gzip sniffing (no Content-Encoding header on compressed bodies), a byte budget enforced mid-transfer, SOAP-fault and async-queue-envelope classification, wide-to-long TSV expansion
• eurostat_query_dataset, both dataframe tools, and three other tool descriptions rewritten to route between a dataset slice and a whole download, and to flag that the two dataframe stagers disagree on obs_flag
• docs: README, design doc, and plugin manifest updated for the new tool

CHANGELOG v0.5.0

v0.4.0: DataCanvas support for the dataframe tools

DataCanvas support for the dataframe tools

• eurostat_query_dataset stages a match past the 5,000-row inline cap onto an optional DuckDB canvas as a flat SQL table, reusing the response body already in memory — no extra request to Eurostat (#8)
• eurostat_dataframe_describe and eurostat_dataframe_query read the staged tables; both are gated off tools/list when CANVAS_PROVIDER_TYPE is not duckdb (#8)
• Dockerfile grants the non-root user writable canvas scratch/export directories; a scratch-directory permission failure now names CANVAS_TEMP_PATH instead of surfacing a bare EACCES
• deps: @duckdb/node-api ^1.5.5-r.3 added as a runtime dependency

CHANGELOG v0.4.0

v0.3.0: dimensions[].valuesCount/sampleValues become optional on dataset_info and the dataset resource

dimensions[].valuesCount/sampleValues become optional on dataset_info and the dataset resource

• Breaking: eurostat_get_dataset_info output and the eurostat://dataset/{dataset_code} resource narrow dimensions[].valuesCount/sampleValues to optional — a failed time-enumeration request now returns partial metadata instead of failing (#34)
• eurostat_query_dataset's 5,000-row cap now applies during decoding instead of after the full match is decoded, with totals from a separate cell scan (#27)
• eurostat_browse_themes resolves a folder code filed under more than one TOC branch to its first placement, with the other branches now disclosed via otherPlacements (#32)

CHANGELOG v0.3.0

v0.2.0: Ten output fields become optional, and Eurostat's silence stops being fabricated as zero

Ten output fields become optional, and Eurostat's silence stops being fabricated as zero

• Breaking: 10 fields move required → optional across 3 schemas — eurostat_get_dataset_info's timeRange.start/end, obsCount, lastUpdated; the eurostat://dataset/{dataset_code} resource's same 4 fields; eurostat_query_dataset's timeRange.start/end (#30, #33)
• get_dataset_info's time-dimension valuesCount now reflects the dataset's real period count instead of a single-period artifact, at the cost of one bounded extra request (#21)
• get_dataset_info's async_response error is no longer retryable — its recovery hint now points at eurostat_search_datasets/eurostat_browse_themes/eurostat_get_dimension_values (#31)
• get_dimension_values rejects geo_level paired with a non-geo dimension instead of silently ignoring it (#25)
• query_dataset drops zero-length filter arrays before building the request and echoes the filters actually applied via a new appliedFilters field (#22)
• docs: design.md and README.md corrected for stale error-code labels, single-request description, and mutual-exclusion wording

CHANGELOG v0.2.0

v0.1.16: TOC cache TTL, cursor binding, and search fixes

TOC cache TTL, cursor binding, and search fixes

Catalogue caching and eurostat_search_datasets pagination/validation, plus mcp-ts-core ^0.11.1 adoption.

• Catalogue TOC now refreshes on a 12h TTL instead of caching for the process lifetime, with stale-on-error fallback (#23)
• eurostat_search_datasets deduplicates matches by dataset code before pagination (#26)
• Search cursors are bound to their query and catalogue snapshot; cross-query, malformed, or superseded cursors reject as invalid_cursor (#28)
• Whitespace-only search queries are now rejected instead of matching everything (#24)
• eurostat_search_datasets / eurostat_browse_themes advertise openWorldHint: true (#29)
• skill/script resync, Dockerfile install hardening, .mcpb bundle now strips native DuckDB bindings too
• deps: @cyanheads/mcp-ts-core ^0.10.14 -> ^0.11.1 (+ typescript, biome, dev-dep bumps)

CHANGELOG v0.1.16

v0.1.15: Content parity, full-range dimension values, live error classification

Content parity, full-range dimension values, live error classification

Three bug fixes: content[]/structuredContent parity for two tools, complete time-range enumeration for get_dimension_values, and invalid-dimension error mapping on the live HTTP path.

Fixed:

• eurostat_query_dataset / eurostat_browse_themes content[] parity — removed the 200-row cap and its truncation note; hasChildren now renders both boolean states (#15)
• eurostat_get_dimension_values full time range — pins every other dimension to enumerate time's complete range instead of the latest period only; geo defaults to geoLevel=country; adds a non-retryable async_response error variant (#17)
• eurostat_query_dataset invalid-dimension error classification — HTTP 400 (Eurostat error id 150) now maps to the declared invalid_dimension contract (ValidationError, -32007) instead of the raw HTTP error (#18)

156 tests pass; bun run devcheck clean.
