Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
DOBOCACHE_LOG_DIROptional | Directory for the local white-box JSONL log. Absolute path recommended. Optional; defaults to the platform log directory: %LOCALAPPDATA%\DoboCache\logs on Windows, ~/Library/Logs/DoboCache on macOS, $XDG_STATE_HOME/dobocache (fallback ~/.local/state/dobocache) on Linux. |
DOBOCACHE_WHITEBOXOptional | White-box report card mode: quiet (default, no card in tool output, log only), once (one card next call, then back to quiet), always (card on every call, ~300+ tokens each). Unrecognized values fall back to quiet with a warning. Cumulative stats are always available via cf_report at no token cost. |
DOBOCACHE_HIT_PRICE_PER_MOptional | Optional price per million tokens for cache-hit tokens used in savings estimates. |
DOBOCACHE_MISS_PRICE_PER_MOptional | Optional price per million tokens for cache-miss tokens used in savings estimates. |
