FAQ from MCP Waifu Chat Server

What dependencies are required?

Python 3.10+, uv package manager, and an OpenRouter API key.

How do I configure the API key?

Set the OPENROUTER_API_KEY environment variable, or create a single-line key file at ~/.api-openrouter.

What database is used?

SQLite by default. The database file path is configurable via the DATABASE_FILE environment variable (default dialogs.db).

Can I use a different OpenRouter model?

Yes. Set OPENROUTER_MODEL_NAME environment variable or create ~/.model-openrouter file. Falls back to openrouter/free.

How do I run in production?

Use Gunicorn with Uvicorn workers (e.g., gunicorn --workers 4 --bind 0.0.0.0:8000 mcp_waifu_chat.api:app -k uvicorn.workers.UvicornWorker). Consider PostgreSQL, logging, HTTPS, and a reverse proxy.
