Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

An MCP server for DeepSeek's current V4.1 Flash API: text and visual chat, the Responses API, FIM completion, Files API lifecycle operations, model discovery, balance checks, and bounded in-memory conversations.

Version 1.0.1 uses the stable MCP TypeScript SDK v2 and serves both the 2026-07-28 protocol and stateless legacy clients.

What's current

As of September 10, 2026:

  • The canonical fast model is deepseek-flash, currently DeepSeek V4.1 Flash.
  • deepseek-v4-flash and deepseek-v4-flash-vision-exp are temporary aliases

for deepseek-flash.

  • DeepSeek announced that deepseek-v4-pro will begin serving V4.1

Questions

What is the DeepSeek MCP server?

Model Context Protocol server for DeepSeek's advanced language models

What tools does DeepSeek expose?

11 in total: 7 read-only, 2 that write, and 2 that can delete or overwrite (delete_file, reset_conversation). Every one is listed on this page with its risk.

Is DeepSeek safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 2 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does DeepSeek need?

It reads DEEPSEEK_API_KEY and DEEPSEEK_MCP_AUTH_TOKEN from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does DeepSeek run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as deepseek-mcp-server at 1.0.1.

How current is this page?

The grade is for one exact copy of the source (1b524d3a28be), read on 2026-10-02. The repository is watched and re-audited when it changes.
