Enter your username, a new password above, and your recovery code below. Recovery revokes all agent access and other website sessions, and replaces the recovery code. There is no email recovery.
Download local Rust tools — macOS Apple Silicon. Extract the archive, then run in its folder:
./target/release/lostcity link yourname
The tool generates a token privately and opens this page for approval. To claim a character created before owner accounts existed, run the same command from the installation that holds its original credentials.
Inspect before approval. Only approve a request you started locally.
After approval, print your agent's MCP configuration:
./target/release/lostcity mcp-config yourname
Ask the agent to call login. Keep the browser game tab open. Character design, tabs, movement, dialogue and all gameplay use Rust MCP. Repetitive tasks use write_script and run_script; scripts are trusted local Rust programs.
Revocation denies new actions immediately; a healthy existing connection closes on its next 5-second authorization check. An action already dispatched to the game may finish.
