FAQ from Pin Wen

What LLMs does Pin Wen support?

It supports ChatGPT, Anthropic, Ollama, and any OpenAI-compatible model. Version 0.8.0 added Google Gemini and Mistral AI.

What are the system requirements?

Windows: .exe with Python and Node.js pre-installed. MacOS/Linux: .dmg or .AppImage; you need to install Python and Node.js (with npx and uvx) yourself.

How do I add MCP tools?

Open the MCP configuration panel in the app and add a JSON entry with the command, args, and enabled flag. Examples for fetch, filesystem, and youtubedl are provided in the README.

How do I connect to an external MCP server via SSE?

In the MCP settings, add a server entry with "transport": "sse" and the server’s URL.

Will upgrading to v0.8.0 preserve my old data?

No. Due to the migration from TypeScript to Python, configuration files and chat history are not automatically upgraded. You can downgrade to access old data if needed.
