    The official MCP server (https://mcp.alphavantage.co/mcp) fronts the API key with OAuth 2.0
    authorization-code + PKCE (S256) and dynamic client registration (RFC 8414 metadata published at
    /.well-known/oauth-authorization-server); the authorization page collects the user's Alpha Vantage
    API key. Scope: alphavantage:read. Legacy API-key-in-URL connection
    (https://mcp.alphavantage.co/mcp?apikey=KEY) is documented as deprecated.
