Quarterly MLIT prices for one city, via reinfolib_quarter. Use it for Japanese real estate and property prices in one city: it returns the number of recorded sales, the median trade price and the first 20 rows for a quarter. These are transaction prices, not the official land prices published as 地価公示.

## Good to know before installing

Sends your REINFOLIB_API_KEY as Ocp-Apim-Subscription-Key to www.reinfolib.mlit.go.jp (HTTPS, XIT001) or the host of REINFOLIB_BASE_URL. Plain http is refused except 127.0.0.1 and localhost, where the key is not encrypted. On for every surface, including gateways, so anyone you allow can call it with your key, with no approval prompt, including unattended cron, yolo, and approvals off. hermes tools does not stop /jp-reinfolib. Stop the slash command with allow_admin_from, user_allowed_commands, group_user_allowed_commands, or by disabling the plugin. After a GET returns, this process waits 1 second before the next, each GET stops after 30 seconds with no bytes, and there is no retry or daily cap. Blueprint jp-reinfolib:weekly-city-check is once a week (default Monday 09:00) and calls only this tool after you schedule it. This plugin does not create a cron job or write a file. A job you schedule stays until hermes cron remove and may include your MCP servers. HTTP 404 means no data for that request, not zero rows and not unchanged prices. A scheduled run is one model turn. A turn that calls the tool is at least two model requests. An empty slash allow list does not stop this tool. R

## How to install

1. Install it. Hermes asks for any API keys it needs (this one needs `REINFOLIB_API_KEY`), then asks whether to turn it on.

```bash
hermes plugins install jp-reinfolib
```

2. Said no? Turn it on later:

```bash
hermes plugins enable jp-reinfolib
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
