Deepseek V4 Claude Code MCP is an open-source MCP server tool developed by Deepseek V4 Claude Code. It connects DeepSeek V4 models, specifically DeepSeek V4 Pro and DeepSeek V4 Flash, with various AI coding agents. This platform-agnostic tool integrates with clients such as Claude Code, Cursor, and OpenAI Codex, extending their capabilities. It provides a means for developers and teams to incorporate advanced DeepSeek V4 model features into their existing AI coding workflows. The tool supports both local stdio transport and remote streamable HTTP connections, offering flexibility for different deployment scenarios. It aims to enhance AI-assisted development by providing access to powerful language models.

What does Deepseek V4 Claude Code MCP connect to?

Deepseek V4 Claude Code MCP serves as a Model Context Protocol server, linking directly to DeepSeek V4 models. Specifically, it establishes connections with DeepSeek V4 Pro and DeepSeek V4 Flash, making their capabilities available to integrated clients. The tool is designed to work with popular AI coding agents, including Claude Code, Cursor, and OpenAI Codex. This integration allows these coding assistants to access the advanced features of DeepSeek V4 models, extending their native functionalities. It supports both local stdio for direct interaction and streamable HTTP for remote access, ensuring broad compatibility.

Core features and tools

Deepseek V4 Claude Code MCP exposes several callable tools for interacting with DeepSeek V4 models. These include chat_completion for DeepSeek V4 chat interactions and completion for DeepSeek V4 Pro FIM completion tasks. Users can also utilize create_response for stateless native Responses API calls. Management tools include list_models to read the live DeepSeek model list, get_user_balance to check account status, reset_conversation to clear in-memory conversations, and list_conversations to view active conversation IDs. It supports stdio and streamable HTTP for client communication.

Who is it for?

This tool is intended for developers and teams who employ AI coding assistants and seek to improve capabilities by integrating DeepSeek V4 models. It is particularly useful for those already using Claude Code, Cursor, or OpenAI Codex and looking to incorporate DeepSeek V4's features into their existing workflows. The tool helps in managing API usage and enhancing the performance of AI-assisted development tasks. Skip this if you do not use AI coding agents or DeepSeek V4 models in your development process.

How to get started

The server authenticates using an API key passed as an environment variable. This involves setting ANTHROPIC_AUTH_TOKEN to your DeepSeek API key and ANTHROPIC_BASE_URL for HTTP transport.

Use cases

• Generate and refactor code efficiently by using DeepSeek V4 models within the Claude Code terminal user experience.
• Improve context and reasoning for large codebases by using DeepSeek V4's 1-million-token context window to analyze entire repositories locally.
• Delegate specific coding tasks from orchestrating agents to DeepSeek V4, preserving main-thread tokens.

Deepseek V4 Claude Code MCP offers a way to integrate DeepSeek V4 models with popular AI coding agents like Claude Code, Cursor, and OpenAI Codex. This open-source tool provides access to various DeepSeek V4 functionalities, including chat and completion, along with model and conversation management. It is designed for developers seeking to enhance their AI-assisted coding environments. Try integrating Deepseek V4 Claude Code MCP with your Claude Code setup to generate code.
