DeepSeek V4 Claude Code FAQs

Question 1

Is DeepSeek V4 Claude Code (DV4-MCP) free, and what are the DeepSeek V4 costs?

Accepted Answer

Yes, DV4-MCP is 100% free and MIT licensed. It includes a free-tier proxy for immediate DeepSeek V4 access. For unlimited use, you can integrate your own DeepSeek API key, which typically costs single-digit dollars per month; these costs are often offset by the significant token savings on your AI coding agent bills.

Question 2

Does DV4-MCP upload my code anywhere?

Accepted Answer

No, your code remains entirely on your machine. DV4-MCP operates locally; the indexer, database, and MCP server are all run on your system, ensuring complete code privacy and security. The only network traffic is to DeepSeek's API via the bundled proxy or your own key.

Question 3

How much can DV4-MCP reduce my AI coding agent token bills?

Accepted Answer

DV4-MCP can dramatically cut token bills, achieving 10–100x reductions on repo-exploration tasks. On average, active users experience a 70–85% token reduction across a typical work week, transforming sessions that previously burned 120,000 tokens into efficient 8,000–15,000 token interactions.

Question 4

How does DV4-MCP differ from other codebase AI tools like RepoMind or Cursor's @codebase?

Accepted Answer

Unlike cloud-hosted solutions (RepoMind, Greptile) that require code upload, or Cursor's in-IDE-only @codebase feature (embeddings-based and subscription-locked), DV4-MCP is local-first, free, open-source, and leverages DeepSeek V4's 1M context without RAG chunking. Crucially, it provides an MCP server, allowing your existing AI coding agents to use it as a smart, precise context layer.
