DeepSeek as Sub-Agent for Claude Code

This is a helper that lets Claude Code (or Codex CLI) pass coding work to DeepSeek, a different AI model. DeepSeek then works inside your project folder: reading files, making edits, and running commands. It is handy if you already use Claude Code and want a second, cheaper worker for bigger jobs like refactors or test writing.

What this MCP server does

You ask Claude Code to do a coding task, like refactor a file or write tests. Claude decides to delegate that task to DeepSeek by calling this MCP server. The server starts DeepSeek in its own loop, letting it read files, make edits, and run commands inside your project folder. When DeepSeek finishes, the result comes back to Claude, which then checks the changes. You see the outcome in your Claude Code chat.

What you can do with it

• Hand off multi-file coding tasks to DeepSeek
• Let DeepSeek read, edit, and run commands in your workspace
• Run read-only analysis tasks without command execution
• Start background jobs you can steer or cancel
• Choose between Flash and Pro DeepSeek models
• Recover from interrupted edits with a mutation journal
• Force delegation with the /ds command in Claude Code

Try asking your AI

• “Refactor the utils folder to use the new logging library”
• “Write unit tests for all functions in math_helpers.py”
• “Scan the logs directory and summarize any errors from yesterday”
• “Inspect this workspace and summarize its structure”

What it gives back to you

You get back a summary of what DeepSeek did, including any files it changed and commands it ran. If it wrote or edited files, you also get a list of those changes so you can review them. For analysis tasks, you get a written conclusion. The result appears in your Claude Code chat as a message from Claude.
