How I14y compares

Against every graded MCP server, from our own scans and uptime checks. Updated after each scan run.

Safety score: 77/100; higher than 50% of 48,255 servers
Tools: 13; the typical server has 7
Tools that change things: 8%; typical: 0%. Fewer write tools means less an agent can break
Downloads a week: 67; more than 52% of 12,191 servers with a package

What its tools let an agent do: 12 read · 1 change

Release history: 2 versions in the registry since 2026-08-03, latest 2026-09-19, typically one every 47 days.

What the publisher says

From the I14y repository's README, as published. We do not edit it. Read it on GitHub

Part of the Swiss Public Data MCP Portfolio — a collection of open-source MCP servers connecting AI agents to Swiss public and open data.

This is a private project. It is not affiliated with, endorsed by, or operated on behalf of any employer or public authority.

i14y-mcp

MCP server for the I14Y interoperability platform — Switzerland's national metadata catalogue.

Why this server exists

The other servers in this portfolio answer «what does the data say?». This one answers the question that comes first: «who publishes data on this topic, through which interface, under which licence?»

I14Y is the national data catalogue maintained by the Federal Statistical Office. It describes datasets, registered APIs, public services and harmonised concepts from the Confederation, cantons and communes, using the DCAT-AP-CH profile (eCH-0200).

Mnemonic: «Catalogue before shelf.» Without a catalogue, an agent has to

already know a data source exists. With one, it can find it.

🎯 Anchor Demo Query

*«Which authority publishes data on special needs education, through which

interface is it available, and under which licence?»*

search_catalog(query="Sonderpädagogik")
  → «Statistik der Sonderpädagogik» — Federal Statistical Office (BFS), theme: Bildung

get_dataset(dataset_id=...)
  → 2 distributions, licence: «Opendata BY ASK — attribution required,
    commercial use only with permission from the data supplier»
  → contact: auskunftsdienst@bfs.admin.ch

Two tool calls turn a vague topic into a named authority, a download URL and a licence you can act on — get_dataset aggregates the distributions, licences and contact point into one record.

Architecture decision

This server uses Architecture A (live API only).

Rationale (verified live on 2026-07-21):

All read endpoints respond without authentication and paginate correctly.
No bulk download of catalogue metadata is offered, and none is needed.
Error responses follow RFC 7807, so failure modes are distinguishable.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.

I14y: common questions

Is I14y MCP server safe?: Mostly: it is graded B (77/100). Read the I14y safety report
How do I install I14y?: It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
Does I14y need an API key?: Not as far as the registry entry and our scan can tell: no credentials are declared or required.
Is I14y maintained?: The last commit was 39 days ago (2026-09-26). The latest release is v0.4.0.
How does I14y compare with other MCP servers?: safety score 77/100 (higher than 50% of 48,255 servers); tools 13 (the typical server has 7); tools that change things 8% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
