It Normattiva MCP Server

@pipeworx/it-normattiva

Italian national legislation — search, resolve an exact URN:NIR citation, and read one article's original-language text as of any date (multivigenza), with publication (Gazzetta Ufficiale) dates kept separate from emanation and in-force dates.

Part of Pipeworx — an MCP gateway connecting AI agents to 1815+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• it_normattiva_search(query?, title?, act_type?, in_force_on?, emanation_date_from?, emanation_date_to?, publication_date_from?, publication_date_to?, limit?, offset?) — search Italian national acts by full-text words, title words, official act type (e.g. "LEGGE", "DECRETO LEGISLATIVO", "DECRETO-LEGGE", "COSTITUZIONE", "REGOLAMENTO") and/or date range. Every result carries a constructed urn field (act type, date and number -- e.g. urn:nir:stato:decreto.legislativo:2003-06-30;196) that chains straight into the two tools below. Free-text query matching is OR-across-words over the whole corpus, not an exact phrase — narrow with title/act_type/dates for tight results.
• it_normattiva_get_act(urn, as_of?, original?) — resolve an exact citation (URN:NIR, e.g. "urn:nir:stato:decreto.legislativo:2003-06-30;196", the Privacy Code) to its title, act type, emanation date, Gazzetta Ufficiale publication date and the opening text (preamble through the start of Article 1). as_of (YYYY-MM-DD) resolves the version in force on that date (multivigenza); original: true returns the text as originally enacted.
• it_normattiva_get_article(urn, article, annex?, as_of?, original?) — the original-language text of one article (e.g. article: "1", "12-bis") of an act, as of a given date. urn is the bare act citation (no article suffix); annex selects an article inside an allegato instead of the main body. Publication, emanation and in-force-from/until dates all come back as separate fields, never folded together.

Both get_act and get_article return found: false with a message (and, if the citation is genuinely ambiguous — most commonly the same act republished across more than one Gazzetta Ufficiale supplement — a candidates list) rather than an error, when nothing or more than one thing resolves.

Data sources

• Istituto Poligrafico e Zecca dello Stato (IPZS), Normattiva Open Data — Italy's official consolidated-law database (laws, decree-laws, legislative decrees, the Constitution, regulations and other national acts), published for the Presidenza del Consiglio dei Ministri. Every act is addressable article by article via its URN:NIR citation and carries its full multivigenza history — the text as amended, plus every historical version with its own in-force window.

Notes

• Multivigenza, concretely: the upstream resolves a version by appending a selector to the citation (!vig=<date> for "in force on this date", @originale for "as enacted") — this pack exposes those as as_of / original rather than asking a caller to hand-build the suffix.
• Article 1's text usually includes the full preamble. Italian decrees and laws place the enacting formula and every "VISTO .../VISTA ..." recital before "Art. 1" in the same structural block the upstream returns, so it_normattiva_get_article with article: "1" (and it_normattiva_get_act with no article) can return a long block of preamble text ahead of the article itself — that is the source's own structure, not truncation or duplication on this pack's part.
• act_type and the urn act-type segment are related but not spelled the same. The URN segment joins the official label's words with dots and turns a hyphen into a dot too ("DECRETO LEGISLATIVO" -> "decreto.legislativo", "DECRETO-LEGGE" -> "decreto.legge"). Build URNs from it_normattiva_search results rather than by hand where possible.
• Keyless, live proxy. One upstream request per tool call. Nothing from Normattiva is baked into the pack or mirrored (the gateway bundle is near its ceiling — see docs/international-legal-scope.md).

Quick Start

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

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/it-normattiva/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 1815+ 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/it_normattiva_search \
  -H 'Content-Type: application/json' \
  -d '{"query":"protezione dei dati personali","act_type":"DECRETO LEGISLATIVO","limit":3}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/it_normattiva_search. 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": {
    "it-normattiva": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-it-normattiva"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-it-normattiva

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 It Normattiva data" })

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