[FEATURE] Add GitLab Integration (Repository Connection, MRs, Mobile Access) #12346

Preflight Checklist

• I have searched existing requests and this feature hasn't been requested yet
• This is a single feature request (not multiple features)

Problem Statement

Currently, Claude Code only supports GitHub as a repository platform. This limits users who work with GitLab (self-hosted or gitlab.com) from utilizing Claude Code's full potential.

Specific limitations:

• Cannot connect GitLab repositories directly to Claude Code
• No way to create Merge Requests (MRs) through Claude Code like with GitHub PRs (gh pr create)
• No browser-based/mobile workflow for GitLab users (GitHub users can use Codespaces + Claude Code on mobile)
• Many enterprises and open-source projects use GitLab as their primary platform

Users who want to use Claude Code with GitLab are currently forced to:

1. Clone repositories locally
2. Work only from desktop machines
3. Manually create MRs through the GitLab web interface
4. Miss out on seamless CI/CD integration that GitHub users enjoy

Proposed Solution

Add first-class GitLab support to Claude Code, similar to the existing GitHub integration:

1. GitLab Repository Connection
   - claude connect gitlab command to link GitLab accounts
   - Support for both gitlab.com and self-hosted GitLab instances
2. Merge Request Support
   - Native gl mr create command (similar to gh pr create)
   - View and respond to MR comments
   - CI/CD pipeline status integration
3. Mobile/Remote Access
   - GitLab Web IDE integration or partnership with Gitpod
   - Enable Claude Code usage from any device via browser
