Public Data Catalog is a remote MCP server that gives an AI agent 3 tools, among them execute, search_data, verify. It answers at https://public-data-catalog-mcp.yusuke8h.workers.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 24 October 2026, succeeded.
Reviewed public-data search and execution with provenance and verifiable integrity receipts.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
execute | Run one allowlisted, bounded HTTPS GET contract and return extracted values, provenance, and an integrity receipt. Inputs: recipeId, parameters |
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. Inputs: query, kind, limit |
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. Inputs: execution |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://public-data-catalog-mcp.yusuke8h.workers.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.yhay81. Endpoint host: public-data-catalog-mcp.yusuke8h.workers.dev. ARD identifier: urn:air:io.github.yhay81:mcp:public-data-catalog.
