MCP server for L2 Calendar — query upcoming Lineage 2 private server openings by chronicle directly from any MCP client (Claude Desktop, Cursor, VS Code, Windsurf, Cline...).
It wraps the free, public, CORS-enabled L2 Calendar API and exposes it as MCP tools.
| Tool | What it does |
|---|---|
list_servers | List tracked servers, ordered by VIP status + opening date. Filters: chronicle, only_upcoming, new_only, min_rate, max_rate, limit. |
get_chronicles | List every chronicle (slug + display name) to use as a filter. |
search_servers | Free-text search across name, website, rate, chronicle, description and labels. |
get_server | Full public record of one server by exact name (case-insensitive). |
list_labels | Distinct labels in use (PTS, Low rate, Craft...) with colors. |
Every result is JSON, ready for the model to reason about.
All data comes from the public API:
GET https://l2calendar.com/api/servers — up to 50 servers per call, optional ?chronicle=<slug> filter.GET https://l2calendar.com/api/chronicles — the chronicle catalog.The API is read-only, requires no key and sends Access-Control-Allow-Origin: *.
Fields returned per server: name, website_url, rate, opening_date, opening_time, opening_datetime_utc, description, is_vip, vip_level, multiproff, multicraft, is_new, chronicle and labels.
Note: the public API returns a single page of up to 50 servers (VIP first, then soonest opening). Tools that filter or search operate on that public page. Increase precision with the
chroniclefilter.
When hosted, point your client at the streamable HTTP endpoint:
GET /health returns { "status": "ok" } for uptime checks.
| Variable | Default | Purpose |
|---|---|---|
L2CALENDAR_API_URL | https://l2calendar.com | Base URL of the L2 Calendar instance to query. |
L2 Calendar is a multilingual (EN/ES/PT/RU) calendar and tracker of Lineage 2 private server openings by chronicle — l2calendar.com.
