Overview

AI-generated overview

Remote MCP server that lets an assistant search over a million Japanese companies and pull profiles, subsidy history and public procurement records from…

What you can do
  • Search companies by prefecture, employee count, capital, founding year and subsidy history, returning corporate numbers for drill-down
  • Read a company profile: representative name and title, employees, capital, establishment date, business summary, website and procurement qualification grade
  • Retrieve the full history of national subsidies received, with dates, program names and granting ministries
  • Look up government contract track record for supplier vetting and public-sector sales intelligence
When to use it
Useful for B2B prospecting and sales research in the Japanese market, building lead lists of companies by size, location or subsidy history, and vetting suppliers through their public contract records. It suits agents that need structured company data rather than web scraping.
Requirements
A remote streamable HTTP endpoint; no local runtime, account or API key is declared in the manifest. The README states usage is billed per tool call, so a paid account on the hosting platform is implied.
Before you install
The README states pay-per-tool-call pricing (about $0.02 per search, profile, subsidy or procurement lookup), so repeated or bulk queries cost money and a 50-company list is estimated at about $1. Queries and returned company details are sent to the remote host and to the underlying government API.

Installation

In SourceWeft

  1. Open Japan Company Leads Finder in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.fujimura-ui%2Fjapan-company-leads-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Japan Company Leads Finder MCP — 日本企業リード検索

B2B lead generation for the Japanese market, powered by official government data.

Search over 1 million Japanese companies by size, capital, location, founding year — and a signal you won't find anywhere else: government subsidy history. Built on METI's official gBizINFO database. 100% legal, no scraping, no stale data.

Why this server?

Prospecting in Japan is notoriously hard for AI agents: no LinkedIn culture, Japanese-only registries, fragmented data. This server gives your sales agent direct access to the government's own company database — including representative names, employee counts, business summaries, and public funding records.

The killer signal: a company that received an IT-adoption or facility-investment subsidy has budget, ambition, and a documented modernization agenda. That's a warm lead, certified by the government.

Tools

search_companies

Filter by prefecture, employee count, capital, founding year, and subsidy history. Returns corporate numbers for drill-down.

get_company_profile

Representative name & title, employee count, capital, establishment date, business summary, company URL, and government procurement qualification grade.

get_company_subsidies

Full history of national subsidies received — dates, program names, granting ministries.

get_company_procurement

Government contract track record — for supplier vetting and public-sector sales intelligence.

Example queries your agent can now answer

  • "Build a list of Tokyo companies, 10–100 employees, that received government subsidies — with CEO names and websites"
  • 「大阪府の製造業で設備投資系の補助金を受給した会社を20社、代表者名付きでリストaップして」
  • "Vet this supplier: what's their government contract history?"

Data source & freshness

Official gBizINFO REST API (Ministry of Economy, Trade and Industry, Japan), fetched live on every call.

Pricing

Pay per tool call ($0.02). One search, profile, subsidy, or procurement lookup = one event. A 50-company lead list with full profiles ≈ $1.
