Overview

Description from the maker (original English)

Japan company, T-number, address and invoice/receipt/card OCR checks, paid per call via x402.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Accounting, finance & tax

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 12 things (tools) jpverify_guide, jp_company_verify, jp_invoice_registration_verify, jp_invoice_issuer_check …
  • The registry lists no key to fill in.

Common questions

Is JPVerify safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.1) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

All tools are read-only (readOnlyHint: true). Registry results are a public-data pre-check, not KYB, AML, sanctions screening, or legal or tax advice.

How payment works

  1. Call a paid tool without payment. The result is an x402 PaymentRequired object (isError: true, structuredContent.accepts[] with the exact USDC amount, payTo and network).
  2. Sign the payment with an x402 client and call the same tool again with the payload in params._meta["x402/payment"].
  3. The tool runs; payment is settled only after a successful result. The settlement receipt is returned in _meta["x402/payment-response"].

Invalid input is rejected before any payment is requested, and failed calls are not charged. MCP clients without an x402 wallet can still use jpverify_guide and the HTTP API documentation.

Example tool call:

{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"jp_invoice_registration_verify","arguments":{"registration_number":"T1013301046627"}}}
