Japan Public Ledgers MCP — questions

Answers built from our own checks of this server.

What can Japan Public Ledgers MCP do?

It exposes 147 tools, read directly from the server on our last check. Among them: agent_audit_query, agent_audit_record, agent_audit_report, agent_captcha_solve, agent_captcha_verify_domain, agent_identity_activities and 141 more. 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 →

What is Japan Public Ledgers MCP mostly used for?

Its tools cluster around agent, commerce and price. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Japan Public Ledgers MCP 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 133 ms. The bar chart above shows every period we have measured.

How do I connect Japan Public Ledgers MCP?

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

Does Japan Public Ledgers MCP need an API key?

No. Japan Public Ledgers MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 147 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Japan Public Ledgers MCP?

It answers our handshake in 133 ms on average, which is faster than 77% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
