# Clearer validation results and Media Library errors

**Version:** v2.46.1

**Published:** November 13, 2026

## Improvements

- `media_library_*` tools: Failed calls now include a stable error code in `_meta["io.sanity/errorCode"]`, including each failed item in bulk calls, so clients can identify failures without parsing error messages.
- Server information: MCP clients now receive a description, website, and Sanity icon when they connect.
- `documents_validate` tool: Results now explain why a document has `complete: false`, listing the checks that did not run.

## Fixes

- `run_sanity_cli` tool: Manage Context knowledge bases again with `sanity context` commands, including commands for sources, documents, instructions, and MCP endpoints.
- Schema validation: When enabled, document creation and patching now reject references to existing documents whose types are not allowed by the deployed schema.
