This adds DeepSeek's chat and code-completion models as something your existing assistant can call mid-conversation, with a thinking mode for harder problems and a running memory of the exchange. It can also report which models are live and what your account balance is. You supply a paid DeepSeek key, or a token for the maintainer's hosted version. Setup is documented for Claude Code, Cursor, and Codex, and the tools cover only what DeepSeek publicly documents, nothing speculative.

Model Context Protocol server for the current DeepSeek V4 API.

As of April 24, 2026, DeepSeek's public API reference documents:

  • POST /beta/completions for V4 Pro FIM completion

This server exposes only those documented API surfaces. It does not ship a V4 monitor, speculative image/video/upload tools, or automatic model substitution.

  • get_user_balance: Reads account balance and availability.

There are documented setups for Claude Code, Cursor, and the Codex command line, plus a hosted version you can point at.
Can I use this to get cheaper answers for routine questions?
