v0.1.0 — Swiss federal finances (EFV)

[0.1.0] - 2026-07-24
Added
Initial release: MCP server for Swiss federal finances (EFV), Architecture C (Dump-first).
Tools: fiscal_headline, fiscal_budget_breakdown, fiscal_by_institution, fiscal_list_dimensions, dump_status.
Dual transport (stdio / SSE), retry with exponential backoff, 24 h TTL cache, Pydantic v2 envelopes with source + provenance.
respx mock tests (Happy / Retry-on-503 / Timeout / Graceful degradation) plus @pytest.mark.live tests against the real endpoints.
Known findings (from live probe 2026-07-24)
403 without UA: data.finance.admin.ch and efv.admin.ch reject the default httpx/curl User-Agent; a browser UA is injected in client.py.
Landing-page trap: opendata.swiss lists two datasets as "CSV" but the URL serves HTML; real files resolved to DAM paths (/dam/de/sd-web/{id}/{name}_de.csv) whose opaque id may rotate on re-upload.
NA-as-string: hh / model / source use the literal "NA" for missing; centralised clean() maps null-ish tokens to None.
Projection is not one label: the Bund labels future years "Budget/financial plans"; the aggregate state (staat) uses "Forecasts". is_projection abstracts over both so agents need not know the taxonomy.
Accounting-model seam 2022/2023: budget topics split into "bis 2022" and "ab 2023"; a note flags affected breakdowns.
Detail cubes deferred: standardauswertung.csv (157 MB) and fir_art_funk.csv (1.23 GB) are out of scope for v0.1.0 (Phase 2: pre-process to SQLite/Parquet).
