What is deepseek-cursor-proxy?

This Python proxy fixes the reasoning_content issue in DeepSeek V4 models (deepseek-v4-pro and deepseek-v4-flash) when used with Cursor, preventing 400 errors during tool calls by caching exact reasoning from responses and restoring it on later turns. It mirrors streamed thinking into Cursor-visible `` blocks for UI display, auto-starts an ngrok tunnel for public HTTPS access, and handles compatibility tweaks like tool schema normalization. Install via pip, run `deepseek-cursor-proxy`, grab the ngrok URL, and set it as Cursor's base URL with your DeepSeek API key.

Why is it gaining traction?

It stands out by safely failing closed on cache misses instead of fabricating data, supports streaming chats with isolated multi-conversation caching, and preserves DeepSeek prefix caching for efficiency—features Cursor users notice in smoother agent flows. The CLI simplicity and verbose logging make debugging tool-call failures straightforward, closing a GitHub fixes issue that blocks DeepSeek thinking mode in Cursor without needing custom hacks.

Who should use this?

Cursor users building agentic coding workflows with deepseek-v4-pro or deepseek-v4-flash, especially those hitting "reasoning_content must be passed back" errors in multi-turn tool calls. Python devs proxying OpenAI-compatible APIs for local testing or BYOK setups.

Verdict

Grab it if DeepSeek + Cursor tool calls are broken for you—solid docs, tests, and config.yaml make setup reliable despite 19 stars and 1.0% credibility score. Alpha maturity means watch for cache edge cases, but it delivers on the core proxy fixes promise.
