hashgraph-online Token Harbor
Use the bundled token-harbor MCP tools whenever the user asks to open the harbor, check Sail Power, inspect port progress, or troubleshoot the companion game.
Main workflow
- Call
open_harborwhen the user wants to play or see the harbor. - Return the local URL as a clickable link. Do not narrate token usage after every Codex response.
- Call
harbor_statusfor a concise progress summary when a full game view is unnecessary. - Treat the harbor as one global world shared by every Codex project.
Privacy
- Token Harbor stores numeric usage totals and game state locally under
PLUGIN_DATA. - It must not collect raw prompts, assistant text, file contents, or tool output.
- Token telemetry is opt-in. Keep
otel.log_user_prompt = falsewhen helping with configuration.
Attention handoff
The game may be active while Codex works. When a task needs approval or finishes, the harbor pauses its active voyage and highlights the task status so the user can return to Codex immediately.
