Release notes

Find new features and important updates to the Prepr MCP server in these release notes.

Manage assets and asset folders with AI

October 15th, 2026

You can now manage your media library through your AI client.

Edit and delete assets. Update the details of existing assets or remove assets you no longer need.
Organize with asset folders. Create, rename, and delete asset folders.

Asset actions follow your user role permissions and the MCP server permissions of the environment.

OAuth now supports organization level

October 8th, 2026

OAuth now allows AI agents to use the MCP server at the organization level. This means you can now connect your AI agent to your organization to view and edit shared schemas across multiple environments.

Manage schemas with AI and schedule unpublishing

October 6th, 2026

You can now manage your content schema through your AI client and schedule when content should be taken offline. This update also improves asset inspection, search, and the field guidance available to your AI client.

Manage your schema (beta). The new schema management tools are available as a beta release. Inspect models, components, and enums, create or update their settings, and add, update, reorder, or remove fields. Schema changes require the appropriate user permissions. Deletions include a preview and require explicit confirmation.
Schedule unpublishing. Ask your AI client to take content offline at a future date and time, in the selected locale.
Inspect assets directly. Retrieve a specific asset by its ID or Prepr asset URL to check its metadata and public file URL before using it in content.
Choose your upload flow. Import an image or document from a public HTTPS URL, or request a pre-signed URL for your client to upload a local file. Preparing a direct upload does not transfer the file; your client must complete the upload separately.
Import files from ChatGPT. Ask ChatGPT to import an attached or generated file into Prepr, then use the returned asset ID in your content. Prepr fetches the file directly, so no separate client upload is needed.
Search with clearer results. Content search returns concise metadata for the selected locale and shows available translations. Your AI client can then retrieve the complete item for detailed inspection.
More predictable tool responses. Tools now expose defined output schemas, helping AI clients interpret results consistently. Search results include clear pagination details and locale-specific content metadata.
Give your AI client better field guidance. Schema inspection exposes enum choices and field validation settings, including minimum and maximum values, regex rules, and whether HTML is allowed. Locale and workflow-stage inputs show the choices available in your environment.
Read complete tool responses. Long text values are no longer truncated by the MCP server, preserving the content returned to your AI client.

Action required: Changes for custom integrations

If you hard-coded specific tools for your AI workflows, take note of the following changes:

get_schema is replaced by list_schema and get_schema_entity for browsing schema definitions and inspecting individual entities.
upload_asset is replaced by upload_asset_from_public_url and create_asset_upload_url. The new upload_asset_from_chatgpt_file tool imports ChatGPT attachments and generated files.
query_items and query_assets now group search conditions under filters.
Supported MCP protocol revisions are 2026-07-28, 2025-11-25, and 2025-06-18. Integrations must use Streamable HTTP; legacy GET-SSE and /messages endpoints are no longer supported.

Fixed filtering issues: filtering on a slug by regex and filtering items that are marked as Needs attention.

Expanded field support and multi-locale handling

June 26th, 2026

This week we expanded editing support for more Prepr field types and improved update behavior across locales.

When publishing a item that fails validation, the MCP server now returns the validation errors

Response limit upped to 2 MB (previous 500kb) to support large items

Improved query for items with ENUM list

June 22nd, 2026

To improve querying items, sort is now updated to an ENUM list of options so the model knows where to choose from.

Improved component handling

June 17th, 2026

Components now support sub-components when editing content
Dynamic content fields in components now can be used like stack fields

Error message for stale sessions

June 17th, 2026

We’ve updated the error message for stale sessions to indicate when you need to restart the client.

The query items tool has been updated to offer a limit up to 50 items per request (instead of 10), and a new has_more property is returned.

Feedback tool available

June 16th, 2026

The Prepr MCP server now exposes a feedback tool for the model to submit feedback.

Agent access mirrors user role permissions

June 15th, 2026

The AI client access to content matches your Prepr user role permissions when making requests. For example, the agent cannot delete content items if your user role Delete permission is disabled in Prepr.

Prepr MCP server domain is updated

June 15th, 2026

The MCP server domain is changed from https://mcp.prepr.io/mcp to https://mcp.prepr.io (the /mcp path is no longer required and is marked as deprecated).

Use Prepr URLs directly in your agent

June 15th, 2026

You can now simply paste the Prepr URL of a specific content item or asset in your agent instead of finding and copying an ID for your agent to identify specific content items or assets.

OAuth support is now available

June 12th, 2026

The Prepr MCP server now supports OAuth. This means it’s easier for you to give access to your AI client access to the Prepr MCP server by simply logging into your Prepr environment.
