# Clearer errors and more reliable authorization

**Version:** v2.35.1

**Published:** September 21, 2026

## Improvements

- Asset uploads: Improved guidance with the exact `Sanity CLI` command, authentication requirements, and a clearer feedback path when an upload is blocked.
- Tool validation: Invalid fields are now identified more clearly.

## Fixes

- Project access: Report a distinct error when Sanity cannot resolve the signed-in user as a project member. The error now names the project and unresolved user instead of looking like a missing permission.
- Studio links: Fixed links to externally hosted Studios.
- `query_documents` tool: GROQ syntax errors now include the query with a marker at the failing position, the expected token, and a trace ID.
- OAuth authorization: Corrected CORS handling while preserving cross-origin access to MCP and supported OAuth API endpoints.
