How to Set Up and Use General-Purpose MCP Tools
The mcp-toolz MCP server is a multi-LLM feedback tool that lets Claude consult ChatGPT, Gemini, and DeepSeek simultaneously through MCP tools. It exposes three tools — ask_chatgpt, ask_gemini, and ask_deepseek — enabling developers to get second and third opinions on code, architecture decisions, and implementation plans directly inside their AI coding workflow. By requiring at least one provider API key, it enables cross-model comparison without switching between different AI interfaces.
Prerequisites
- Python 3.8 or higher, or Node.js for npx usage
- At least one API key from: OpenAI (OPENAI_API_KEY), Google (GOOGLE_API_KEY), or DeepSeek (DEEPSEEK_API_KEY)
- An MCP client such as Claude Desktop or Claude Code
- pip or uv package manager for installation
Install mcp-toolz via pip
Install the mcp-toolz package using pip or uv. This installs the MCP server and its command-line entry point.
pip install mcp-toolz
# or with uv:
uv tool install mcp-toolzObtain API keys for your desired LLMs
Get API keys for the LLM providers you want to use. You need at least one. OpenAI keys start with sk-, Google API keys come from Google AI Studio, and DeepSeek keys from platform.deepseek.com.
Add mcp-toolz to Claude Desktop or Claude Code configuration
Edit your MCP client configuration to add mcp-toolz with your API keys in the env block. Only include keys for providers you have access to.
Restart your MCP client
Restart Claude Desktop or reload Claude Code after updating the configuration. The three LLM tools (ask_chatgpt, ask_gemini, ask_deepseek) should now appear.
Optionally configure model overrides
Set optional environment variables to pin specific model versions for each provider. The defaults are gpt-5 for OpenAI, gemini-2.0-flash-thinking-exp-01-21 for Google, and deepseek-chat for DeepSeek.
export MCP_TOOLZ_MODEL=gpt-4o
export MCP_TOOLZ_GEMINI_MODEL=gemini-1.5-pro
export MCP_TOOLZ_DEEPSEEK_MODEL=deepseek-coderGeneral-Purpose MCP Tools Examples
Client configuration
Add mcp-toolz to your Claude Desktop claude_desktop_config.json. Include API keys for each provider you want to enable. All three are optional — only providers with keys will be available.

}Prompts to try
Use these prompts to get multi-LLM perspectives on your code. Claude will invoke the appropriate ask_* tool and return the other model's response.
- "Ask ChatGPT to review this function for potential bugs"
- "Get Gemini's opinion on whether I should use a microservices or monolith architecture for this use case"
- "Ask DeepSeek to suggest a more efficient algorithm for this sorting implementation"
- "Get all three LLMs to review this API design and summarize their consensus"
- "Ask ChatGPT and Gemini whether this SQL query could have a race condition"Troubleshooting General-Purpose MCP Tools
ask_chatgpt returns authentication error
Verify OPENAI_API_KEY is set correctly in the env block of your MCP config. The key must start with 'sk-'. Check your OpenAI account billing status at https://platform.openai.com/account/billing as the API requires an active payment method.
mcp-toolz command not found after pip install
The mcp-toolz entry point may not be on your PATH. Try using the full path: run 'which mcp-toolz' or 'python -m mcp_toolz' instead. Alternatively, use 'uvx mcp-toolz' in the command field which handles PATH resolution automatically.
Only some LLM tools appear in Claude
Tools are only registered for providers where an API key is supplied in the env config. If ask_gemini is missing, ensure GOOGLE_API_KEY is set. Restart the MCP client after adding new keys.
