organic

organic_jas_changes

Which organic JAS listings were added to, changed in, dropped from or returned to MAFF's official lists since a date? From this service's own record of list versions (MAFF keeps no old files). Each change has the listing id, observed_at, last_seen_at, changed fields and before/after; personal-looking names are withheld and the reason for a drop is not published or inferred. History starts at tracking_since. Free window: last 30 days.

organic_jas_lookup

Is this operator in Japan's official MAFF list of organic JAS certified operators (domestic or foreign)? Look up by certification number, operator name (2+ chars, organizations only), country, prefecture, category or certifier. Returns found, no_longer_listed (reason not published or inferred), no_match_in_checked_list (does not mean not organic) or unknown, with certifier, category, municipality or country, certified_on, first/last seen. Confirm with the certification body.

What can Japan Organic JAS Certified Operators do?

It exposes 4 tools, read directly from the server on our last check. Among them: catalog, get_receipt, organic_jas_changes, organic_jas_lookup. 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 Japan Organic JAS Certified Operators 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 1166 ms. The bar chart above shows every period we have measured.

How do I connect Japan Organic JAS Certified Operators?

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 Japan Organic JAS Certified Operators need an API key?

No. Japan Organic JAS Certified Operators completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Japan Organic JAS Certified Operators?

It answers our handshake in 1166 ms on average, which is faster than 3% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
