Oneinfo Storage

@pipeworx/oneinfo-storage

Italian regulated company disclosures direct from 1INFO — a document index (title, issuer, category, timestamp, document link), updated same-day, covering the ~314 issuers that use 1INFO instead of eMarket Storage as their Officially Appointed Mechanism (OAM) for EU Transparency Directive filings.

Part of Pipeworx — an MCP gateway connecting AI agents to 1807+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• oneinfo_search_disclosures(company?, ndg?, category?, date_from?, date_to?, limit?, offset?) — search disclosures by issuer (name, resolved against 1INFO's own 314-issuer list, or a known ndg), category, and/or a publication date window. Returns newest first.
• oneinfo_get_disclosure(id, date) — fetch one disclosure by its protocolCode and publication date (both come from a prior search — this source has no by-id-only lookup).

Why this pack exists — and why it's separate from emarket-storage

Italy has TWO Officially Appointed Mechanisms for Transparency Directive disclosures: eMarket Storage (Teleborsa) and 1INFO. An issuer discloses through exactly one of the two — there is no overlap, so neither pack can be dropped in favor of the other. Confirmed live 2026-09-24: 1INFO's own 314-issuer list includes IREN and SOMEC, both absent from eMarket Storage's picklist; roughly half of STAR-segment issuers use 1INFO. If a company isn't found here, try emarket-storage's emarket_search_disclosures instead (and vice versa — emarket-storage's not-found note points back here).

⚠️ Five things a caller must know

1. 1INFO-covered issuers only — not the full Italian market. A company search that matches nothing returns an explanatory note, not a bare error, pointing at emarket-storage instead. This pack does not merge eMarket Storage data.
2. This is a document index, not an XBRL-facts API. Every row is a disclosure EVENT: a title, an issuer, a category, a publication timestamp, and a link to the underlying document. There is no per-fact extraction. For XBRL facts (net income, revenue…) from Italian ANNUAL reports, use esef-filings (proxies filings.xbrl.org) — measured 2026-09-24: annual filings from 1INFO issuers (SOMEC, IREN, Softlab) reached filings.xbrl.org about 6 days after they were stored here. There is no XBRL-facts source anywhere for HALF-YEAR reports (ESEF is annual-only by construction), so this pack is the only structured way to see those land.
3. No ISIN. LEI appears only embedded in the filename of XBRL-tagged annual-report ZIPs (has_xbrl: true rows — e.g. 81560001692D0424C949-2025-12-31-1-it.html inside SOMEC's FY2025 ZIP). Identify issuers by name (resolved against 1INFO's own list) or by ndg (1INFO's internal numeric id) directly once you have it from a prior search.
4. date_to is INCLUSIVE (the last local-calendar day you want, Europe/Rome). Unlike emarket-storage, this pack filters dates itself client-side rather than passing a range upstream, so there's no exclusive-upstream-bound trap to work around — verified live 2026-09-24: date_from=2026-09-22&date_to=2026-09-22 returns the one disclosure actually published that day (UNIDATA), proving the last day is included.
5. No server-side filter by issuer exists on this source. Verified live 2026-09-24: 1INFO's /API/Documenti endpoint honors SearchFilter[categoria] (it genuinely narrows the result set) but silently IGNORES both SearchFilter[ndg] and the DataTables global search[value] — recordsFiltered is identical with or without them. This pack resolves a company to ndg and filters CLIENT-SIDE while paging the (always storage-date-descending) result set. A date_from/date_to window is scanned to completion (bounded to 6 upstream requests / ~6,000 rows as a safety cap); an open-ended company-only search stops as soon as it has limit matches, which is cheap but may miss an issuer's older filings. Every response says honestly how far it scanned (scanned.oldest_date_local, scanned.stopped_reason) and whether matched_in_scanned_range is an exact count for the range (range_fully_scanned: true) or only a lower bound — never a fabricated total.

Auth

Keyless. No account, no API key.

Data sources

• https://www.1info.it/PORTALE1INFO/ — 1INFO's public disclosure storage portal (an EU Transparency Directive OAM for Italy). Pipeworx queries its JSON API live on every call; there is no bulk download.

Gotchas

• No formal REST API — this is a DataTables server-side endpoint. POST /PORTALE1INFO/API/Documenti requires the standard DataTables form fields (draw, columns[0][...], order[0][...], start, length); a bare POST missing them fails with a server-side NullReferenceException. GET /PORTALE1INFO/API/companies/documenti (314 issuers) and GET /PORTALE1INFO/API/documenti/Categories are plain GETs.
• The download URL needs a .pdf suffix 1INFO's own JSON does not show — a silent-404-shaped trap. PdfShow.aspx takes a file (the document code) and a year (the fiscal year) query parameter. When a row has an XBRL package (protocolCodeXbrl non-null, e.g. "165960_oneinfo.zip"), that value downloads as-is. But when protocolCodeXbrl is null — every half-year report, every ancillary filing, i.e. most rows — using the bare protocolCode (e.g. "171904_oneinfo") 302-redirects to Error.aspx …documento non trovato with no indication of what went wrong. Appending .pdf ("171904_oneinfo.pdf") is what actually resolves — confirmed live 2026-09-24 on three different issuers/categories (UNIDATA REGEM, Banca Sistema 3.1, SOMEC 1.2), each 302 without the suffix and HTTP 200 with it.
• year is the FISCAL year from dataEsercizio, not the storage year — and it can differ between two filings stored on the very same day for the very same report: SOMEC's FY2025 annual report was stored as two sibling rows (the ESEF-format ZIP and a plain-PDF twin) 2 minutes apart, with year=2025 for one and year=2026 for the other — both confirmed live to need exactly their own computed year, not the other's.

• Company-name resolution uses rankMatches (exact > prefix > whole-word

  substring) against 1INFO's own issuer picklist, embedded at

  /API/companies/documenti. An ambiguous match (multiple issuers tied at the same score) returns candidates instead of guessing.

• The categoria filter accepts multi-value rows — a single disclosure can carry more than one code (e.g. "1.2,2.2"); category_labels reflects every code on the row, while filtering by category matches on membership, not exact equality.
• Dates are computed in Europe/Rome via Intl.DateTimeFormat (DST-correct) rather than manual UTC offsets — dataStoccaggio/dataEsercizio are raw Unix-seconds timestamps with no timezone marker in the source JSON.
• oneinfo_get_disclosure has no direct by-id endpoint on the source — it re-scans that day's listing (up to 3 requests / 3,000 rows, far more than any single day's market-wide volume — 33,444 rows measured over roughly 5 years) and matches on protocolCode.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "oneinfo-storage": {
      "url": "https://gateway.pipeworx.io/oneinfo-storage/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/oneinfo-storage/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1807+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/oneinfo_search_disclosures \
  -H 'Content-Type: application/json' \
  -d '{"date_from":"2026-09-17","date_to":"2026-09-24"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/oneinfo_search_disclosures. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "oneinfo-storage": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-oneinfo-storage"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-oneinfo-storage

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Oneinfo Storage data" })

The gateway picks the right tool and fills the arguments automatically.
