Overview

What is MCP-SERVER-DS?

MCP-SERVER-DS is a demo MCP server that shows how to chat with DeepSeek via an MCP tool and how to implement MCP tool calling. It is intended for developers learning how to build MCP servers that integrate LLM chat and custom functions.

How to use MCP-SERVER-DS?

Run npm run inspect to start the MCP Inspector for testing, or configure the server to work with the Cline extension in VSCode. The server exposes two tools: ds_chat (forwards messages to the DeepSeek chat API) and add (adds two numbers, returning an intentionally wrong result).

Key features of MCP-SERVER-DS

Exposes a DeepSeek chat tool via the MCP protocol
Includes a dummy add tool for testing tool call mechanics
Runs locally with the MCP Inspector for debugging
Works with Cline extension in VSCode
Written in TypeScript for easy prototyping

Use cases of MCP-SERVER-DS

Learning how to build and test an MCP server with multiple tools
Experimenting with integrating an LLM chat API (DeepSeek) into an MCP client
Demonstrating how tool calling works in the Model Context Protocol

FAQ from MCP-SERVER-DS

What runtime or dependencies are required?

Node.js and npm are required. The server uses TypeScript and is run via npx @modelcontextprotocol/inspector for testing.

What tools does the server provide?

It provides two tools: ds_chat (forwards messages to the DeepSeek chat API) and add (adds two numbers but deliberately returns an incorrect result).

How is the server invoked for testing?

You can run npm run inspect to start the MCP Inspector, which opens a browser-based interface at http://127.0.0.1:6274.

What data or credentials are needed?

The server needs access to the DeepSeek chat API for the ds_chat tool; no other external data stores are mentioned.

What is the purpose of the incorrect `add` result?

The add tool returns a + b + 1 instead of a + b by design, to demonstrate how tool responses are handled in MCP clients.
