Assets upload, schema discovery, and improved image field validation

Published: August 18, 2026

v2.30.0

New Features

  • Schema discovery: Agents can now discover every deployed schema source for a project and dataset, then inspect a specific source with its exact schema ID when workspace names overlap.
  • Assets upload bridge: Agents with outgoing network call capability and authenticated Sanity CLI access can now use the dataset_assets_upload tool to upload supported image and file types via local Sanity CLI.

Planned expansion for MCP-native assets upload

In current state, agents operating in outgoing network call-restricted sandboxes or contexts that prohibit authenticated Sanity CLI use may still require a human-in-the-loop to upload assets, either through direct Sanity API calls and/or manual Studio actions. We’re actively working toward enabling fully MCP-native assets upload.

Improvements

  • generate_image and transform_image tools: Improved path validation for image fields in documents.
