Week of October 5, 2026
What shipped
- The 1.14.0 release adds support for authorized views with dataset restrictions, includes LookML dashboards in the
get_dashboardstool, propagates the requester header on Firestore collection listing forget_schema, and carries other changes. Release - Skills list and skills get are now served over MCP with the skills extension declared on the 2026-07-28 protocol, grouping skills per request from the default group's resources so a reload shows up on the next request. Pull request #4050
- The looker
get_dashboardstool now includes LookML dashboards, which were previously excluded because the search only queried user-defined dashboards. Pull request #4216 - Config load now warns on skill resources that sit under no SKILL.md, listing orphaned URIs next to the duplicate-name warning. Pull request #4048
- Resource template URI schemes are now normalized to lowercase during validation, matching what resource URI validation already did. Pull request #4023
- Timeouts on both context and polling were increased for datalineage. Pull request #4227
- The cloud-gda integration test shard now also runs on conversational analytics changes and tolerates soft-deleted agents. Pull request #4160
- An Airlock setup script for Cloud Build was added, with APT, PIP and Docker container downloads proxied through Airlock and a.dockerignore to keep credentials out of the Docker context. Pull request #4144
- The Looker test expectation was updated because newer Looker instances return an empty list instead of an unsupported API error for legacy features. Pull request #4231
- Hugo was updated for the release. Pull request #4233
Why it matters
This week brings the 1.14.0 release, which adds authorized views with dataset restrictions, brings LookML dashboards into the get_dashboards tool, and fixes the requester header on Firestore collection listing. It also serves skills list and skills get over MCP and makes config load warn about skill resources that belong to no skill. Resource template URI schemes are now normalized so configs using mixed-case schemes validate as written.
