This is the third-party server itself — Odel doesn't run it. Hitting this URL directly talks straight to the upstream server with no auth or proxying. Connect through Odel to front it with managed auth.

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.

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.
