Code Review
This pull request updates the MCP server implementation to return tool execution errors (such as invalid parameters or URL binding conflicts) as successful JSON-RPC responses with IsError: true and the error details in the content, rather than returning JSON-RPC protocol-level errors. It also refactors PopulateUrlParams to return an error when a client attempts to provide a parameter that is bound by the URL, and switches to using util.DecodeJSON for array and map parameter parsing. Additionally, the default supported extension com.google.cloud/toolbox.v1 is registered and verified in the 2026-07-28 protocol version. I have no feedback to provide as there are no review comments.
