l2calendar-mcp

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.

Tools

ToolWhat it does
list_serversList tracked servers, ordered by VIP status + opening date. Filters: chronicle, only_upcoming, new_only, min_rate, max_rate, limit.
get_chroniclesList every chronicle (slug + display name) to use as a filter.
search_serversFree-text search across name, website, rate, chronicle, description and labels.
get_serverFull public record of one server by exact name (case-insensitive).
list_labelsDistinct labels in use (PTS, Low rate, Craft...) with colors.

Every result is JSON, ready for the model to reason about.

Data source

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 chronicle filter.

Install

Remote (HTTP) — no install

When hosted, point your client at the streamable HTTP endpoint:

{
  "mcpServers": {
    "l2calendar": {
      "type": "http",
      "url": "https://<your-host>/mcp"
    }
  }
}
Local (stdio) via npx
{
  "mcpServers": {
    "l2calendar": {
      "command": "npx",
      "args": ["-y", "l2calendar-mcp"]
    }
  }
}
Local (stdio) from source
git clone https://github.com/Dreiev/l2calendar-mcp.git
cd l2calendar-mcp
npm install
npm run build
{
  "mcpServers": {
    "l2calendar": {
      "command": "node",
      "args": ["/absolute/path/to/l2calendar-mcp/dist/index.js"]
    }
  }
}

Run the HTTP transport

node dist/index.js --http            # http://127.0.0.1:8787/mcp
node dist/index.js --http --port 9000

GET /health returns { "status": "ok" } for uptime checks.
