Measured tools (12)

• search_econ_series read-only

  Search the Econ Data Library catalog (billions of series from hundreds of sources: national accounts, prices, trade, labor, energy, markets…). Free, no key needed. Returns series ids usable with get_econ_series. Page with offset; lang returns source-official translated titles where the publisher provides them.

  Parameters:

  • query (required) — string — Free-text search, e.g. 'germany inflation' or 'GDP per capita'
  • lang — string — Title language. Only official translations are shown; a title without one stays in English.
  • limit — integer
  • offset — integer — Skip this many results (paging). The API caps how deep it pages and says so if exceeded.
  • source — string — Restrict to one source id, e.g. 'worldbank', 'ecb', 'imf_weo'

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_econ_series read-only

  Download an economic time series as rows (long format: date, value) with its citation and license. REQUIRES the free ElkassabgiData API key. Use date_from/date_to to window long series.

  Parameters:

  • series_id (required) — string — Exact catalog id from search_econ_series, e.g. 'worldbank:NY.GDP.MKTP.CD:DEU'
  • date_to — string
  • max_rows — integer
  • date_from — string

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_econ_series_metadata read-only

  Full metadata for one econ series: title, frequency, geography, unit, license (incl. commercial-use flag), attribution/citation, coverage dates. Free, no key needed.

  Parameters:

  • series_id (required) — string

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• list_econ_sources read-only

  List the Econ Data Library's sources (statistical offices, monetary authorities, IGOs, research datasets) with their licenses, counted live. Free.

  Parameters:

  • contains — string — Case-insensitive filter on source id/name, e.g. 'bank' or 'imf'

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_data_freshness read-only

  Live per-source update status straight from the automated updater's ledger: last successful update, data frontier, and honest stale/failure flags (dates are NEVER fabricated — a silent upstream outage shows here as stale, not papered over). Free.

  Parameters:

  • source — string — One source id; omit for the full board

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_econ_bundle_manifest read-only

  A citable bundle manifest (Frictionless data package) for several econ series - up to 50 explicit ids, or every series of one small source (up to 1,000 series): the per-series download URLs grouped by source, each source's attribution and licence, and any id that could not be resolved (reported, never dropped). The URLs serve the CURRENT data - this is not a frozen vintage. Free, no key needed for the manifest; downloading the URLs needs the key.

  Parameters:

  • ids — array — Up to 50 exact catalog ids from search_econ_series
  • source — string — One source id - every series of that source, if it has at most 1,000

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_hf_download_link read-only

  Authenticated download instructions for HF Data Library's 1-minute OHLCV bars (per-ticker US stocks/ETFs from IEX Exchange HIST, 2022-03-07 to the present; parquet or csv) or the 25 pre-computed academic variables. Each file holds all of a ticker's bars, so it is fetched by YOUR code, not returned inline. The data is provided for academic research; relay that notice with the link. Works with the same ElkassabgiData key.

  Parameters:

  • ticker (required) — string — e.g. AAPL, SPY
  • format — string — csv only applies to bars
  • dataset — string
  • version — string

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_hf_variables_dictionary read-only

  The exact definitions/formulas of HF Data Library's 25 pre-computed academic variables (realized volatility family, spreads, jumps, liquidity, data-quality). Verbatim from the published dictionary. Free.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• list_ip_bundles read-only

  List the IP Data Library's snapshot-pinned patent/innovation bundles (patent-level measures on US patents; assignee-year panels) with sizes, vintages and download paths. Free, no key needed.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_ip_download_link read-only

  Authenticated download instructions for an IP Data Library bundle — patent-level innovation measures (citations, originality/generality, grant lag, team size) or the assignee-year panel. Parquet, full-history files fetched by YOUR code, not returned inline. Works with the same ElkassabgiData key as every family library.

  Parameters:

  • file (required) — string
  • vintage — string — Snapshot vintage from list_ip_bundles; omit for the newest

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_family_status read-only

  Live status of the whole ElkassabgiData family - HF, Econ and IP: each library's headline stats and data currency, read live. Free.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_auth_status read-only

  Whether this MCP connection has an ElkassabgiData API key configured (masked — the key itself is never echoed), and how to add one.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared
