L2Tools MCP

A public, read-only MCP server providing deterministic access to Lineage 2 reference data for Interlude and High Five chronicles. It allows AI agents to search NPCs, retrieve loot tables, calculate Soul Crystal transition probabilities, and compute XP ranges using normalized, versioned datasets with explicit provenance.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

90-day uptime

A lightweight connection check about every six hours, sampled on hosts with many listings. It shows the server answered, not that its tools work.

Too few checks for a percentage yet (2 of 2 answered).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http l2tools-mcp https://l2tools.org/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add l2tools-mcp --url https://l2tools.org/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable l2tools-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "l2tools-mcp": {
      "url": "https://l2tools.org/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "l2tools-mcp": {
      "type": "streamableHttp",
      "url": "https://l2tools.org/api/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start l2tools-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "l2tools-mcp": {
      "type": "http",
      "url": "https://l2tools.org/api/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http l2tools-mcp https://l2tools.org/api/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "l2tools-mcp": {
      "serverUrl": "https://l2tools.org/api/mcp"
