What
When Claude Code checks whether an MCP (Model Context Protocol) server URL is allowed, it now recognizes a second valid pattern: a URL whose path matches a toolbox format and includes a toolbox_mcp_server_id query parameter with exactly one matching value. This is in addition to the existing rule that allowed a plain path with no query parameters.
Why
This lets Claude Code connect to Toolbox MCP servers identified by this URL format, which it previously would not have recognized as valid.
