"""
Example 1 — DeepWiki MCP (free, no API key).

DeepWiki (by Cognition) exposes an MCP server that can read and answer
questions about the documentation of any public GitHub repository. It is
completely free and requires **no authentication**, so this example runs
out of the box.

    Server : https://mcp.deepwiki.com/mcp
    Auth   : none
    Tools  : read_wiki_structure, read_wiki_contents, ask_question

The Agent auto-detects the transport from the URL scheme (an ``https://``
URL uses streamable-HTTP), fetches the server's tools on startup, and the
model calls them as needed to answer the task.

Run:
    export OPENAI_API_KEY=...        # or ANTHROPIC_API_KEY, etc.
    python 1_deepwiki_repo_qa.py
