GitLab Orbit Hackathon: Building Context-Aware AI Agents
💡Learn how to build AI agents that understand your entire software development lifecycle using GitLab Orbit and MCP.
⚡ 30-Second TL;DR
What Changed
GitLab Orbit provides a real-time, queryable graph of code, pipelines, and deployments.
Why It Matters
By centralizing system context, GitLab Orbit allows AI agents to move beyond file-level tasks to system-wide orchestration. This significantly reduces the time engineers spend digging through siloed tools for root-cause analysis.
What To Do Next
Explore the Model Context Protocol (MCP) documentation to see how you can connect your own internal tools to AI agents for better system-wide context.
Key Points
- •GitLab Orbit provides a real-time, queryable graph of code, pipelines, and deployments.
- •Developers used Model Context Protocol (MCP) to connect AI agents to system-wide context.
- •Top projects included automated blast-radius analysis and AI-driven issue briefing.
- •Community contributors merged 61 improvements directly into the Orbit codebase.

🔑 Enhanced Key Takeaways
- •GitLab Orbit utilizes a proprietary graph database architecture that maps relationships between commits, CI/CD pipeline stages, and cloud infrastructure resources in real-time.
- •The hackathon specifically emphasized the integration of MCP (Model Context Protocol) to standardize how AI agents query GitLab's internal APIs without requiring custom connectors for every tool.
- •Participants utilized GitLab's new 'Contextual Awareness Engine' which allows agents to perform cross-repository dependency analysis, identifying how a change in one microservice impacts downstream deployments.
- •The event saw the introduction of 'Agentic Workflows' within GitLab, enabling autonomous agents to open, test, and verify merge requests based on the root-cause analysis performed by the Orbit graph.
- •Data from the hackathon indicates that agents leveraging the Orbit graph reduced the time-to-resolution for complex dependency-related bugs by approximately 40% compared to standard LLM-based code assistants.

🛠️ Technical Deep Dive
- Orbit Graph Architecture: Employs a directed acyclic graph (DAG) structure to represent the lineage of code from source to production environment.
- MCP Implementation: Uses the Model Context Protocol to expose GitLab's internal GraphQL API as a set of standardized tools for LLMs, allowing agents to perform 'read' operations on pipeline logs and infrastructure state.
- Contextual Awareness Engine: A middleware layer that performs vector embedding of code snippets combined with metadata from the graph to provide RAG (Retrieval-Augmented Generation) with high-fidelity system context.
- Blast-Radius Analysis: Implemented via graph traversal algorithms that calculate the transitive closure of dependencies for a given code change, identifying all affected downstream services and infrastructure components.
