How to install Cheaplane

Copy-paste configuration for popular MCP clients.

transport: stdio

Config generated by PluginBench — verify against the source before use.

Environment / auth

DELEGATE_BASE_URL
OpenAI-compatible endpoint serving the cheap models — usually a local LiteLLM proxy.
DELEGATE_API_KEY
secret
Key for that endpoint. A local proxy ignores it; set a real one for a hosted endpoint.
DELEGATE_TIMEOUT
Per-call timeout in seconds. Raise it for long documents.
DELEGATE_MODEL_MAP
JSON remapping the built-in aliases to your proxy's model names, e.g. {"deepseek": "deepseek-v4"}.
DELEGATE_NO_LOG
Set to 1 to disable the local savings ledger (metadata only, never task content).
