Auth

The server now owns the LeekWars session.

Required env vars:

• LEEKWARS_LOGIN

• LEEKWARS_PASSWORD

Optional env vars:

• LEEKWARS_AUTH_RETRY_DELAY_MS

• LEEKWARS_API_BASE_URL

• LEEKWARS_SCRIPTS_DIR (defaults to src/tools)

• LEEKWARS_SOCKET_URL

• LEEKWARS_SOCKET_PROTOCOLS (comma-separated)

• LEEKWARS_SOCKET_CONNECT_TIMEOUT_MS

• LEEKWARS_SOCKET_REQUEST_TIMEOUT_MS

• LEEKWARS_SOCKET_MAX_BUFFERED_EVENTS

• MCP_SERVER_NAME

Tool registry

Tools are manifest-driven from src/tools/manifest.ts and executed through src/tools/registry.ts.

Tool output kinds:

• json - stdout only

• markdown - stdout only

• text - stdout + stderr formatting

Testing

• npm test - smoke tests for manifest loading, output formatting, and representative tool execution

• npm run check - typecheck only

• npm run build - compile to dist/

Scripts

• npm run dev - run in watch mode

• npm run start - run compiled server

Fight logs

fetch_fight_logs uses Playwright. If the browser binary is missing, install it with:

npx playwright install chromium

Socket bridge

The socket bridge connects to wss://leekwars.com/ws by default (override with LEEKWARS_SOCKET_URL) and uses the LeekWars session auth headers. It exposes bridge tools:

• socket_connect

• socket_status

• socket_send

• socket_call

• socket_recv

• socket_close

Encyclopedia tools

Encyclopedia search and page retrieval live in the separate leekwars-mcp-encyclopedia server. Configure both MCP servers if you need both game actions and encyclopedia knowledge tools.
