Sanity Expands MCP Asset Uploads, SAML Enforcement and Insights

On October 19, 2026, Sanity published an overview of its October platform updates. The main changes concerned AI agents working with media files through MCP Server, employee access management with SAML SSO, and analytics of AI interactions in Sanity Context. The new capabilities make it possible to automate content transfers, strengthen control over corporate authentication, and analyze AI response quality using additional parameters.

Uploading Images and Files Through Sanity MCP Server

In October, Sanity expanded MCP Server with four tools for uploading media files. Previously, AI agents could transfer text content to Sanity, but users had to take separate steps to upload images and documents. Agents can now upload files from public URLs, local storage, and the web version of ChatGPT directly to a Sanity Dataset or Media Library.

Four tools are available for this purpose: dataset_assets_upload_from_url uploads files from a public URL to a Dataset; media_library_upload_from_url performs the same operation for Media Library; dataset_assets_upload_from_file works with local files; and dataset_assets_upload_from_web_chatgpt allows attachments and files created in ChatGPT to be sent to a Dataset.

The update simplifies website migration and media content management. For example, an AI agent can transfer articles and images from an old website to Sanity, after which the files become available through the Sanity CDN. To transfer materials from closed systems, users must first download the files to a local device and then send them through the appropriate MCP Server tool.

Restricting Access for Users Without SAML SSO

Sanity added the Prevent non-SAML users setting, which lets organization administrators require corporate authentication through SAML SSO for new members. The feature is available to organizations with SAML SSO support, including the Enterprise plan, and can be enabled in Sanity Manage under Settings > SAML SSO.

Once the setting is activated, new users can accept an invitation or request access to the organization only through the corporate identity provider. An attempt to join using another authentication method prompts the user to sign in through SAML.

The restriction is disabled by default. It applies only to new members and does not revoke access from existing users who previously signed in without SAML. To move an organization fully to corporate authentication, administrators must separately review these accounts and remove them if necessary. Sanity also warns that duplicate accounts are not merged automatically, so assigned roles and permissions must be checked before old accounts are removed.

Custom Parameters for Analyzing Sanity Context Insights

Another October update concerned Insights, the Sanity Context analytics tool for evaluating interactions with AI agents. The system analyzes conversations, assigns success and sentiment scores, and helps identify content gaps that reduce response quality.

Custom parameters can now be sent to Insights as key-value pairs. The added parameters automatically become available in the analytics interface for filtering and drilling down into results.

For example, a company can send a user’s subscription plan, service region, or other characteristics of an interaction. Teams can then compare response quality across segments and identify situations where the overall success rate remains high but the AI regularly struggles with questions from a particular group of users.

The setting is available in the Insights section of the Sanity Context application. It allows AI agent performance to be connected to the business context of interactions rather than relying only on overall conversation statistics.
