04_multi_server_agent.py

"""
Example 4 — Multiple MCP servers on one agent (all free, no API key).

Pass a list to ``mcp_urls`` and the agent loads the tools from *every*
server and can use them together in a single run. Here we combine two free,
no-auth servers so the agent can cross-reference a GitHub project (DeepWiki)
with official Microsoft documentation (Microsoft Learn).

    Servers : https://mcp.deepwiki.com/mcp
              https://learn.microsoft.com/api/mcp
    Auth    : none

The model sees the union of both toolsets and decides which to call.

Run:
    export OPENAI_API_KEY=...        # or ANTHROPIC_API_KEY, etc.
