Product Update: June 2026

Since our last update, we've shipped new MCP servers for agents and developers, a new CLI for declarative deployments, and Single Sign-On for Self-Managed. Here are some of the highlights; for the full list of changes, see the release notes.

• MCP Server for Agents (public preview). We now have a built-in MCP server for agents, so AI agents can discover and query the data products you've published in Materialize through a single endpoint, with role-based access control over which agent can see what.
• MCP Server for Developers (public preview). Our MCP server for developers gives coding agents diagnostic access to your Materialize environment, so you can ask natural-language questions like "why isn't this view fresh?" to troubleshoot freshness, hydration, and resource issues without leaving your editor. It pairs with our coding agent skills, which give coding agents working knowledge of Materialize patterns and troubleshooting playbooks.
• mz-deploy. A new Rust-based CLI that lets you define sources, views, indexes, clusters, and other Materialize objects as code. Projects compile locally with no running Materialize instance, so you can run unit tests, inspect query plans, and validate changes in a sandbox before touching a shared environment.
• Single Sign-On on Self-Managed (public preview). Self-Managed Materialize now supports SSO via OIDC-compliant identity providers like Okta, Microsoft Entra ID, Auth0, and Keycloak, so you can provision users through your existing identity provider. Username and password authentication still works alongside it.
• Performance and efficiency improvements. Several improvements, including a major CPU reduction on views that use temporal filters (75% down to 4% in our tests), up to 65% faster DDL operations at scale, 17x faster storage usage collection, and roughly 10% faster materialized view hydration.
