GitLab Repos, Issues, and Merge Requests

Work with GitLab projects, issues, merge requests, and branches through the gateway. Connect with your own GitLab OAuth application.

Overview

OneCLI connects AI agents to GitLab through OAuth. Agents can read projects, open and update issues and merge requests, comment, and manage branches. The gateway injects the token into every request, so your agent never sees it.

GitLab uses your own GitLab OAuth application, on OneCLI Cloud and self-hosted alike. Setup takes about five minutes, once.

Connect GitLab

1. Create a GitLab OAuth application

   In GitLab, open User settings > Applications and click Add new application. Name it OneCLI, and select the scopes api, read_user, read_repository, write_repository, and read_registry.

   

   The Add new application form in GitLab.

2. Add the redirect URI

   In OneCLI, open Connections > GitLab > Custom credentials and copy the Redirect URI. Paste it into the GitLab application’s Redirect URI and save the application.

   

   After saving, GitLab shows the Application ID and the Secret. Copy the secret now, GitLab shows it only once.

3. Add your credentials and connect

   Copy the GitLab Application ID and Secret into Custom credentials, click Save credentials, then click Connect GitLab and Authorize in GitLab.

   

   The GitLab connect window in OneCLI before credentials are added.

What agents can do

Area	What agents can do
Projects	List and read projects, list branches
Issues	List and read issues. Create, update, and comment on issues
Merge requests	List and read merge requests. Create, update, comment on, and merge them
Branches	Create and delete branches

Controlling access

Grant the connection to each agent that needs it, and choose per tool what runs freely, what needs approval, and what’s blocked. Put Merge merge request and Delete branch behind approval. Organization rules add guardrails on top. A blocked request never reaches GitLab.

To disconnect, remove the connection in Connections > GitLab, then revoke OneCLI in GitLab under User settings > Applications.
