Jp M2m Gateway tools (5)

write = sends, deletes, buys or posts
  • get_gazette_financialsFree

    Statutory financial disclosure (決算公告) raw text blocks, parsed from gazette page scans by a Vision LLM. Paid via x402: each call costs 0.05 USDC. This tool returns the HTTP 402 payment challenge for the resource. Private beta note: a successful settlement is acknowledged with a receipt that records your priority access; the dataset itself unlocks for early settlers as provisioning goes live.

  • get_government_recordsFree

    FREE during beta — returns live data. Un-aggregated procurement contracts, subsidy grants and certifications, pulled on demand from gBizINFO upstream. Source: gBizINFO (経済産業省), attribution included in every response.

  • get_pension_headcount_logFree

    Un-aggregated month-over-month insured headcount deltas (健康保険・厚生年金) for one Japanese corporate number. Paid via x402: each call costs 0.05 USDC. This tool returns the HTTP 402 payment challenge for the resource. Private beta note: a successful settlement is acknowledged with a receipt that records your priority access; the dataset itself unlocks for early settlers as provisioning goes live.

  • list_company_datasetsFree

    Free catalog lookup. Lists the raw regulatory datasets available for one Japanese corporate number with per-call x402 pricing (0.05 USDC per call). Use the dataset tools or the returned api_url to retrieve data.

  • search_corporationsFree

    FREE — returns live data. Resolve Japanese company names to 13-digit corporate numbers (法人番号) via gBizINFO. Use the corporate number with the dataset tools.

JP Raw M2M Data Gateway — MCP Server

Remote MCP (Model Context Protocol) server exposing raw Japanese regulatory corporate data to AI agents, metered per call with the x402 payment protocol.

  • MCP endpoint (Streamable HTTP, stateless): https://jp-m2m-gateway-62ko7b2uwa-an.a.run.app/mcp
  • Machine index: llms.txt · API contract: openapi.yaml · Catalog: JSON-LD dataset pages

Unlike generic corporate registries, this gateway serves un-aggregated, regulatory-enforced raw logs for Japanese companies, keyed by the 13-digit corporate number (法人番号):

Connect

Listed on Smithery and the official MCP Registry (io.github.kodandy/jp-m2m-gateway).

Claude Code:

claude mcp add --transport http jp-m2m https://jp-m2m-gateway-62ko7b2uwa-an.a.run.app/mcp

Generic MCP client configuration:

{
  "mcpServers": {
    "jp-m2m": {
      "type": "streamable-http",
      "url": "https://jp-m2m-gateway-62ko7b2uwa-an.a.run.app/mcp"
    }
  }
}

No API key and no initialize handshake required — the server is stateless; tools/call works directly.

How payment works (x402)

Paid tools return a structured HTTP 402 payment challenge instead of data:

{
  "status": 402,
  "error": "Payment Required",
  "dataset": "pension",
  "amount_usdc": 0.05,
  "x402": { "header": "X-402-Payment-Required", "descriptor": "usdc_request_mock_v1_base_…" },
  "resource": "https://…/v1/companies/{corporate_id}/pension",
  "how_to_pay": "Settle 0.05 USDC via x402, then retry the resource with an X-PAYMENT header."
}

Per-resource descriptors are stable. x402 settlement (USDC on Base, testnet first) is being enabled during the current private beta; agents that send X-PAYMENT retries are prioritized for access.

Notes

  • Machine-to-machine only. Human/browser UX is intentionally not provided — browsers receive a plain-text 402 by design.
  • Status: closed private beta. Endpoints, pricing and datasets may change.
  • Source of the gateway lives in a private repository; this repo hosts the public MCP server documentation and registry manifest.
