dsh-llm-cursor

If you already hold a Cursor subscription and want to route those models through your own DeepSeek Harness agent loop, dsh-llm-cursor was built for that. It authenticates via Cursor's private Deep Control PKCE endpoint and sends chat requests over HTTP/2 + protobuf to the AgentService/Run interface, letting DSH remain the sole agent loop and tool executor without requiring a separate API plan.

Core capabilities include browser-based PKCE login with sessions stored locally on the Host, automatic model catalog discovery with thinking-level SKU collapsing, flexible Fast and 1M context-tier management, live subscription usage display, and a tiered retry policy with full Run lifecycle and binding management. DSH keeps all tool-calling, MCP integration, and multi-model orchestration; Cursor serves purely as a model route.

A critical caveat: this plugin talks to Cursor's unofficial private client endpoints. Cursor staff have stated that this class of usage violates their Terms of Service section 1.5, and accounts may be restricted or permanently banned. It is intended for experienced DSH users who already hold a Cursor subscription and have fully weighed that risk; it is not suitable for teams that treat a Cursor account as production-critical infrastructure.
