## Quality 80/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers

### Tool changes

- 2026-10-11 `get_hf_download_link` changed (description)
  - before: Authenticated download instructions for HF Data Library's 1-minute OHLCV bars (per-ticker US stocks/ETFs from IEX Exchange HIST, 2022-03-07 onward; parquet or csv) or the 25 pre-computed academic variables. Each file holds a ticker's whole history, so it is fetched by YOUR code, not returned inline. HF downloads are paused while the dataset is restructured (the URL answers 503 data_paused). Works with the same ElkassabgiData key.
  - after: 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.

- 2026-10-02 `get_econ_bundle_manifest` added
  - 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.

- 2026-10-02 `search_econ_series` changed (description, inputSchema)
  - before: Search the Econ Data Library catalog (billions of series from 300+ sources: national accounts, prices, trade, labor, energy, markets…). Free, no key needed. Returns series ids usable with get_econ_series.
  - after: 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.

## Packages

_none_

## Tools (12)

- `get_auth_status`: Whether this MCP connection has an ElkassabgiData API key configured (masked — the key itself is never echoed), and how to add one.
- `get_data_freshness`: 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.
- `get_econ_bundle_manifest`: 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.
- `get_econ_series`: 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.
- `get_econ_series_metadata`: Full metadata for one econ series: title, frequency, geography, unit, license (incl. commercial-use flag), attribution/citation, coverage dates. Free, no key needed.
- `get_family_status`: Live status of the whole ElkassabgiData family - HF, Econ and IP: each library's headline stats and data currency, read live. Free.
- `get_hf_download_link`: 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.
- `get_hf_variables_dictionary`: 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.
- `get_ip_download_link`: 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.
- `list_econ_sources`: List the Econ Data Library's sources (statistical offices, monetary authorities, IGOs, research datasets) with their licenses, counted live. Free.
- `list_ip_bundles`: 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.
