Cheaplane MCP

Cheaplane is a community-built MCP server that offloads replaceable grunt work from premium AI agents to cheaper models via a local LiteLLM proxy. It features auto-routing to select the appropriate cheap model based on task type, physically isolated billing processes to protect premium subscriptions, and a savings ledger to track token cost reductions.
