Google Antigravity agents get full context with GitLab Orbit (opens in new tab)
Google Antigravity agents can now access GitLab’s broader software lifecycle context through GitLab Orbit, available in the Antigravity MCP Store. Orbit builds a knowledge graph connecting code, projects, dependencies, merge requests, pipelines, users, and vulnerabilities, allowing agents to answer questions that would otherwise require manual research across GitLab. GitLab reports that internally tested agents using Orbit were up to 11 times faster, used 4.5 times fewer tokens, and hallucinated up to 45 times less. ## GitLab Orbit Adds Lifecycle Context - Antigravity agents can normally access files and terminals but lack information about: - Service dependencies - Related vulnerabilities - Merge request history - Code ownership and reviewers - Pipeline performance - Orbit indexes GitLab and exposes its knowledge graph through: - `query_graph` for structured lifecycle queries - `get_graph_schema` for available node types, properties, and relationships - Agents receive typed results through GitLab Orbit’s JSON query DSL. ## Practical Development Use Cases ### Blast radius analysis - Engineers can identify which projects depend on a module before refactoring it. - Agents can also find open merge requests affecting those files and identify their owners. - This reveals conflicts and stakeholders before changes are made. ### Onboarding and codebase exploration - Agents can explain a service’s dependencies, entry points, and recently opened merge requests. - Results can be captured in a persistent Walkthrough Artifact rather than disappearing in chat. - Orbit reindexes changes within minutes, keeping documentation more current than static wikis. ### Live architecture diagrams - Agents can query service dependencies and render them as diagrams using Nano Banana Pro. - Diagrams can be filtered, such as showing only services with unresolved security findings. - Access controls apply to every query, making generated diagrams safe to share. - GitLab is developing similar functionality through its Software Architecture Map. ## Installation Through the MCP Store - Open Antigravity settings and go to the customization tab. - Find the MCP section and select **Add MCP**. - Choose GitLab Orbit and authenticate with GitLab. - No configuration files or terminal commands are required. ## Availability and Technical Details - Orbit uses the same context engine as GitLab Duo Agent Platform. - It supports code indexing for Ruby, Java, Kotlin, Python, TypeScript, JavaScript, Rust, and C#. - Code is indexed from the default branch and refreshed within minutes. - MCP queries consume GitLab Credits, while `get_graph_schema` calls are free. - The feature is available to GitLab Premium and Ultimate customers on GitLab.com. For teams already using GitLab and Google Antigravity, GitLab Orbit provides a governed, current context layer that can make agents more accurate and useful. Teams should enable Orbit for a top-level group and install it through the Antigravity MCP Store, while accounting for GitLab tier requirements and credit usage.
