Read-Only Mode

Restrict the server to only expose read-only operations.

Configuration

GITLAB_READ_ONLY_MODE=true

Behavior

When enabled:

• Only browse_* and other read-only tools are available
• All manage_* tools are hidden from the tool list
• manage_context is the sole exception (session context, no GitLab data modification)
• Write operations return an error if attempted
• Useful for production environments or when write access is not needed

Use Cases

• Production monitoring — Safely browse projects, MRs, and pipelines
• Cursor/Windsurf — Stay within the 40-tool limit by hiding write tools
• Shared access — Give agents read access without risk of modifications
• Auditing — Browse activity and history without accidental changes
