What you can ask

Six conversations that ship today.

Carrier MCP collapses dozens of OCS REST calls into a handful of high-level intents. Tap a card to see a real prompt.

  • Activate eSIM

    Provision a subscriber and assign a regional package in a single prompt.

  • Diagnose Subscriber

    Get a full health report on any line — registration, usage, balance, errors.

  • Fleet Health Report

    Aggregate health across thousands of subscribers in one pass.

  • Revenue Analysis

    Break down ARPU, churn, and package mix across the reseller tree.

  • Coverage Analysis

    Inspect which networks a package can attach to and where it falls back.

  • Bulk Operations

    Move populations of subscribers between packages, statuses, and accounts.

Install in 30 seconds

One click, or one block.

Cursor and VS Code install from a link. Claude Code and Codex take the command below. Or copy the prompt and let an agent do the whole thing, verification included.

Step 0 · required

Create a Carrier account first. MCP tools need Clerk auth (OAuth) or an org API key — install configs alone will not work.

Step 1 · one click

Add to CursorAdd to VS Code

Cursor and VS Code install on click. Claude Code and Codex publish no install URL, so those buttons copy the exact command. “Copy prompt” hands any agent the install and a read-only check to prove it worked.
