What the publisher says

From the PlugRail JP Corporate repository's README, as published. We do not edit it. Read it on GitHub

plugrail

A collection of MCP servers that connect to Japanese public data. The name alone does not describe the project, so plugrail is not related to railways or railway services.

Live servers

Connect

See the jp-calendar connection guide.

Self-hosting

  1. In packages/servers/jp-calendar/, copy wrangler.example.jsonc to wrangler.jsonc and fill in your Cloudflare resource IDs.
  2. Create the D1 database and KV namespace referenced by that configuration.
  3. Run pnpm --filter @plugrail/jp-calendar deploy.

The self-hosted server runs independently. Authentication, rate limiting, and usage metering are features of the hosted service only.
