Built-in providers now default the audience to the MCP server's resource identifier, with an explicit opt-out, instead of disabling audience validation. Assisted-By: Claude Opus 4.7 <noreply@anthropic.com> Signed-off-by: Sergey Vilgelm <sergey@vilgelm.com>

📌 Summary
Every shipped auth provider passed
validate_audience: None, disablingaudvalidation. A token issued for another resource could therefore be replayed against this server. Audience validation is now on by default, defaulting to the MCP server's resource identifier (mcp_server_url), with an explicit opt-out.🔍 Related Issues
