Major lets you deploy internal tools directly from your laptop while keeping access governed in one place. Engineers who build internal apps use the CLI to:
  1. Deploy code instantly – scaffold apps from templates, push with a single command, and ship a new version in seconds.
  2. Manage access & permissions – assign roles in the web editor and ensure every action respects RBAC.
  3. Connect to internal connectors securely – route database and API traffic through the Major control plane instead of punching new holes in your network.
Local traffic always flows local app → Major API → resource. When you run major app start, we mint a short-lived JWT in your .env file so every request is authenticated through the platform.

AI tool integration (MCP)

Major exposes CLI documentation and guidance via the Model Context Protocol (MCP). If you use AI tools like Claude Desktop or Cursor, you can configure them to access Major CLI commands, workflows, and troubleshooting prompts directly. Add the Major MCP endpoint to your AI tool’s configuration to get context-aware assistance when working with Major projects.
