  note: >-
    The hosted MCP server (mcp.tradier.com) authenticates with the same API token
    via an API_KEY header or api_key query parameter plus a PAPER_TRADING flag,
    and separately publishes RFC 8414 OAuth metadata (issuer
    https://p-be-auth.tradier.com, scopes openid/mcp/claudeai, PKCE S256) — see
    well-known/tradier-mcp-oauth-authorization-server.json.
