FAQ from MCP Client Streamlit Interface

What MCP server does the interface connect to?

The interface connects to a server defined by the script path (default server.py). No specific MCP server implementation is mandated, but the included environment expects a Gemini‑backed server.

Which API keys are required?

A GEMINI_API_KEY is required for the language model. An optional SERPAPI_KEY enables web search functionality.

What platforms or Python versions are supported?

The interface requires Python 3.13 or newer. It runs on any platform that supports Streamlit (Windows, macOS, Linux).

Is the interface free to use?

The README does not mention pricing. You pay for your own API usage (Gemini API, SerpAPI); the interface itself is open‑source.

Are there any known limitations?
