search_data

Search current metadata from e-Gov Data Portal and Statistics Dashboard, then return a short ranked list with publisher, formats, coverage, usage terms, and official links.

execute

execute

Run one allowlisted, bounded HTTPS GET contract and return extracted values, provenance, and an integrity receipt.

verify

verify

Check receipt and result hashes plus the execution envelope against the reviewed catalog. This detects later modification; it does not prove publisher authenticity or current freshness.

Public Data Catalog — questions

Answers built from our own checks of this server.

What can Public Data Catalog do?

It exposes 3 tools, read directly from the server on our last check. Among them: execute, search_data, verify. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Public Data Catalog working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 231 ms. The bar chart above shows every period we have measured.

How do I connect Public Data Catalog?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Public Data Catalog need an API key?

No. Public Data Catalog completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Public Data Catalog?

It answers our handshake in 231 ms on average, which is faster than 62% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Public Data Catalog open source?

The code is open source: it is published under the MIT licence, written in Python, 0 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at public-data-catalog-mcp.yusuke8h.workers.dev, which runs on its operator's own terms.
