Unichat MCP Server in Python

What is Unichat MCP Server in Python?

Unichat MCP Server in Python is an MCP server that sends requests to multiple AI providers (OpenAI, MistralAI, Anthropic, xAI, or Google AI) using a single tool or predefined prompts. It requires a vendor API key and is intended for developers integrating AI capabilities via the Model Context Protocol.

How to use Unichat MCP Server in Python?

Install by configuring Claude Desktop with the server command and environment variables, or by using npx -y @smithery/cli install unichat-mcp-server --client claude. Set the UNICHAT_MODEL (e.g., gpt-4o-mini) and UNICHAT_API_KEY (your vendor API key) in the environment. The server provides one tool (unichat) and four prompts (code_review, document_code, explain_code, code_rework).
