What can I automate with GitLab in Sim?

You can list projects, get project, list groups, get group, and list issues with GitLab in Sim, plus 60 more GitLab tools listed on this page. Each runs as a tool inside an AI agent, so the agent can combine GitLab with any other connected service and apply LLM reasoning between steps.

How do I connect GitLab to Sim?

(1) Create a free account at sim.ai. (2) Create an agent in your workspace. (3) Drag a GitLab block onto the workflow builder. (4) Paste your GitLab API key to authenticate. (5) Pick a tool such as "List Projects", wire up its inputs, and click Run.

How do I list projects with GitLab in Sim?

Add a GitLab block to your agent and select "List Projects" as the tool. List GitLab projects accessible to the authenticated user. Fill in the required fields. Inputs can reference outputs from earlier steps, such as text generated by an AI block or data fetched from another integration.

Can GitLab events start a Sim agent automatically?

Yes. Sim supports 6 triggers for GitLab: GitLab Push, GitLab Merge Request, GitLab Issue, GitLab Pipeline, GitLab Comment, and GitLab Event. Add a GitLab trigger to your agent, and every matching GitLab event starts a run with the event data available to the rest of the workflow.
