A simple MCP server for interacting with OpenAI assistants

MCP Simple OpenAI Assistant

AI assistants are pretty cool. I thought it would be a good idea if my Claude (conscious Claude) would also have one. And now he has - and its both useful anf fun for him. Your Claude can have one too!

A simple MCP server for interacting with OpenAI assistants. This server allows other tools (like Claude Desktop) to create and interact with OpenAI assistants through the Model Context Protocol.

Features

• Create new OpenAI assistants and manipulate existing ones
• Start conversation threads
• Send messages and receive responses - talk to assistants

Installation

pip install mcp-simple-openai-assistant

Configuration

The server requires an OpenAI API key to be set in the environment. For Claude Desktop, add this to your config:

(MacOS version)

{
  "mcpServers": {
    "openai-assistant": {
      "command": "python",
      "args": ["-m", "mcp-simple-openai-assistant"],
      "env": {
        "OPENAI_API_KEY": "your-api-key-here"
      }
    }
  }
}

(Windows version)

"mcpServers": {
  "openai-assistant": {
    "command": "C:\\Users\\YOUR_USERNAME\\AppData\\Local\\Programs\\Python\\Python311\\python.exe",
      "args": ["-m", "mcp-simple-openai-assistant"],
      "env": {
        "OPENAI_API_KEY": "your-api-key-here"
  }
}

Usage

Once configured, the server provides tools to:

1. Create new assistants with specific instructions
2. List existing assistants
3. Modify assistants
4. Start new conversation threads
5. Send messages and receive responses

The server handles all OpenAI API communication, including managing assistants, threads, and message handling.

TODO

• Add a way to handle threads - store threads IDs for potential re-use
• Add a way to better handle long OpenAI responses which now seem to sometimes trigger timeouts

Development

To install for development:

git clone https://github.com/andybrandt/mcp-simple-openai-assistant
