Ireland MCP

Ireland MCP

Ask ChatGPT, Claude or Copilot about Ireland, and get answers that cite official public sources.

Ireland MCP is a free connector for AI assistants. It lets your assistant look up Irish public data, such as census figures, train times, weather warnings, house prices and Dáil business, and tell you where every number came from. Website: irishopendata.ie.

• Free, with no account or API key. Paste one web address into your assistant.
• Read-only. It only looks things up. It cannot change or submit anything.
• Official sources. Answers come back with the publisher, licence and the time the data was fetched, so you can check them.
• Open source under the MIT licence. An unofficial community project, not a government service.

What can I ask?

• “What is the latest population profile for Galway city or County Cork?”
• “Are there Met Éireann weather warnings near Dublin today?”
• “What did houses sell for in Ennis last year?”
• “When is the next train from Heuston, and are there disruptions?”
• “Who are the current TDs for my constituency, and what bills are active?”
• “What protected habitats, monuments, planning applications or census areas are near this point?”

The assistant writes the answer; Ireland MCP supplies the data and its source. Check the date and source before you rely on a figure.

The server address is https://mcp.irishopendata.ie/mcp. It needs no sign-in.

• ChatGPT: Plugins → + → Add custom MCP server → paste the address → No authentication. Full steps.
• Claude: Settings → Connectors → Add custom connector → paste the address.
• GitHub Copilot CLI:

  copilot mcp add --transport http ireland https://mcp.irishopendata.ie/mcp

• VS Code: add .vscode/mcp.json:

  { "servers": { "ireland": { "type": "http", "url": "https://mcp.irishopendata.ie/mcp" } } }

Check it works. Ask: *"Using the ireland tools, give me the Census 2022 profile of Ennis, Co Clare, and the Met Éireann forecast for Galway. Cite the sources."* The answer should link https://data.cso.ie/table/F1015 and the Met Éireann forecast URL. †

† The forecast URL is http://: Met Éireann's https:// host currently redirects to an origin that fails TLS.

Beta features

Beta features are off on the hosted server. You can turn them on when you run your own copy.

Beta: Irish law & your rights (annual leave and working time)

Not legal advice. For your own situation, contact Citizens Information, the Workplace Relations Commission or a solicitor.

An optional pilot finds Irish employment-law evidence and quotes it with links. It covers only two topics today: annual leave and working time.

• What it reads: two Citizens Information guidance pages, the Organisation of Working Time Act 1997 and the Irish Statute Book page listing that Act's later changes.
• Act text is as passed in 1997. It may not include later amendments. Check the changes page and the cited source.
• Citizens Information blocks automated access today. Its firewall refused the pilot's requests on 26 October 2026, so a sync may fetch only the Irish Statute Book pages. We will not disguise the pilot as a browser. Wider coverage needs permission or an official export from the Citizens Information Board; we are asking.
• AI summaries can be wrong. Every answer quotes its sources. Read them.

Without the beta, the default legislation source quotes Irish law as enacted, live from the Irish Statute Book. In this revision that covers Acts, statutory instruments and the Constitution; check ireland_describe for what a given server offers. The beta adds Citizens Information guidance and stored, versioned evidence.

Try it on your own machine:

npm run legal:sync    # fetch the seed pages into .irish-legal-cache

npm run legal:serve # chat page and tools at http://127.0.0.1:4173

legal:sync exits with an error while any page fails. Today that is expected for the Citizens Information pages; the Irish Statute Book pages are still saved.

Or add it to the main server with LEGAL_ENABLED=true (off by default). Read the beta assessment and pilot guide first.

For developers: endpoint details

Hosted endpoint: https://mcp.irishopendata.ie/mcp Transport: Streamable HTTP. Auth: none. Writes: none. Registry: io.github.c-mongan/ireland-mcp on the official MCP Registry.

What's inside

Last full run of every operation then in the catalogue against the hosted endpoint: docs/live-all-ops.md (2026-10-26): 78 of 82 pass, 1 fail; 3 need an operator key (NTA, Logainm).

The default profile covers statistics (CSO, Eurostat, ECB, World Bank), the Oireachtas and Irish Statute Book, Met Éireann, transport (Irish Rail, Luas, NTA, TFI stops, bikes), property, planning, heritage, environment, energy, tourism, lobbying, pay-gap reports, council budgets and more. An optional Irish legal and Citizens Information pilot is off by default; see Beta features.

All 39 sources, publishers and licences

The default profile registers 39 source modules in src/registry.ts. The default nearby, ireland_resolve_place, search and fetch shortcuts sit above these sources. ireland_resolve_place maps any place to its county, council, LEA, constituency, NUTS3 and ED codes; see the place crosswalk. The optional pilot rows require LEGAL_ENABLED=true and an ingested corpus; check ireland_catalogue for the modules available on an endpoint. See new provider access and limits.

For counts, sums, joins and rankings over many rows, ireland_query loads whole tables on the server (CSO tables, planning applications, Pobal scores, crosswalk lists, property sales, pay-gap reports, EU projects and council budgets) and returns only the answer rows, with each input's provenance. planning_search returns exact totals and pages with offset; planning_stats counts applications and proposed homes nationally. See server-side queries.

Every source has a dataset card: topics, geography levels, time coverage, update cadence, join keys and licence. Ask ireland_catalogue for, say, {"geo_level": "lea", "topic": "housing"} to list only the operations with that data, and ireland_describe with a source for its full card.
