The user asks the AI to farm. The AI calls get_status, set_path and set_alert, asks permission for begin_combat, then L2Walker starts fighting and the AI reports the results.

How it works

MCP (Model Context Protocol) is a standard way for AI apps to call tools in other programs. L2Walker runs a small MCP server on your computer; your AI app connects to it and can read the walker’s state and — with your OK — control it.

01
You ask
Type a request in your AI app, in any language.
Claude · ChatGPT · …
02
AI picks tools
It decides which L2Walker tools to call and with what settings.

03
L2Walker answers
The local MCP server reads the panels or — after your OK — changes them.

04
You get a result
The AI explains what happened and what it would do next.
Plain-language reply

Your account, password and license key never go to the AI. It only sees what the tools return.

What the AI can use

Tools L2Walker exposes over MCP. Read tools run freely; action tools ask you first.

Tool	What it does	Panel in the app	Access
get_status	Character, level, HP/MP/CP, server and license state	Toolbar · status bar	Read · free
list_nearby	Players, monsters, NPCs and items around you with distance	Player / Mon / NPC	Read · free
read_log	Recent combat and chat lines	Combat Info · L2 Info	Read · free
get_party	Party members, buffs and who is dead	Party	Read · free
get_map	Position, combat range and path points	Virtual Map	Read · free
begin_combat / stop	Start or stop farming	Toolbar	Action · asks first
set_path	Center point, radius, path points	Option › Path	Action · asks first
set_alert	Sound or stop when HP drops, a whisper arrives or a PK is near	Option › Sound Alerts	Action · asks first
load_profile	Load a saved Option file	Setup › Load Option	Action · asks first
logout	Log the character out safely	System	Action · asks first

Tool names are a proposal — final list: [MCP TOOL LIST].

You stay in control

Local only

The server listens on your own computer (127.0.0.1). Nobody on the internet can reach it.

Ask before acting

Every action tool waits for your approval in the AI app. Turn on auto-approve per tool if you want.

Read-only mode

One switch limits the AI to reading status, logs and the map.

No secrets shared

Game password, license key and account details are never sent to the AI.

Only for servers that allow bots

L2Walker does not bypass or work around server protection (anti-bot and anti-cheat systems), and it is not made for servers where bots are prohibited. Use it only on servers whose rules allow bot programs — check your server’s rules before you start.

Questions

Which AI apps work?

Any app that supports MCP: Claude Desktop, ChatGPT with custom connectors, Cursor and others. [CHECK LIST BEFORE LAUNCH]

Does it need a license?

[LICENSE RULE — e.g. read tools free, action tools need a personal or server license].

Does the AI see my screen?

No. It only gets the data the tools return — status, lists, logs — as text.

Can it play while I’m away?

It can start, stop and adjust farming within the limits you set, and stop when an alert you configured fires.

Is my data sent anywhere?

Tool results go to the AI app you chose and follow that app’s privacy rules. L2Walker itself sends nothing extra.
