Official MCP servers for Japanese services (2026)
This page lists only MCP servers that the vendors of widely used Japanese SaaS products publish themselves. Each one was checked against the vendor’s official documentation or official GitHub repository on 2026-10-15. Configs are copied from those docs, with API keys left as placeholders.
freee-mcp
What it does: Operate nine freee areas from chat: accounting, HR & payroll, invoicing, time tracking, sales, IT management, tax filing, fixed assets and business start-up (for example “create an invoice” or “show this month’s trial balance”).
- Published by: freee K.K. (official, beta)
- Type: Remote (hosted by the vendor)
Install config
Claude Code (terminal)
claude mcp add --transport http freee https://mcp.freee.co.jp/mcpJSON (Cursor, Claude Code .mcp.json, etc.)
{
"mcpServers": {
"freee": {
"type": "http",
"url": "https://mcp.freee.co.jp/mcp"
}
}
}In Claude Desktop or claude.ai, open Customize → Connectors → Add custom connector and enter https://mcp.freee.co.jp/mcp.
Notes: The remote version is hosted by freee; you only sign in to freee and approve the app. freee asks you to install its Agent Skills (freee-api-skill.zip) so the AI uses the tools correctly. An open-source local version (npx freee-mcp) is also available.

Before you start
- These servers handle accounting and HR data, so check that your AI tool is set not to use your inputs for training (freee’s terms ask for this).
- Never commit config files that contain API keys or passwords.
- Local servers run with your permissions. Read the security checklist first.
