Free and Open Source

The Seller Labs AI Toolbox for Amazon Sellers

A free set of MCP servers, slash commands and a task scheduler that turn Claude Code into an assistant that works on its own schedule. Point Claude Code or Codex at the repo and tell it to set you up.

Setup

Let Your AI Agent Install It

The repo ships with SETUP.md, an ordered guide from a bare machine to a working stack. Your agent reads it and runs the steps. You handle the logins.

  1. 1

    Install the basics

    Node.js 18 or newer, git, and an AI coding agent. The toolbox is built and tested with Claude Code in VS Code.

  2. 2

    Paste this prompt into Claude Code or Codex

    Clone https://github.com/sellerlabs/slt-toolbox-public and set me up by following SETUP.md in order. Stop and ask me whenever you need a token or a login.
  3. 3

    Hand over your own keys when asked

    Each tool uses your own account and API token, stored on your machine. The setup order matters, and the guide explains why: Lazy Hub goes first, then Playwright, then everything else.

What’s Inside

Tools That Take Work Off Your Plate

The pieces most useful to an Amazon seller, and what each one does for you.

Task Scheduler Windows only

Runs Claude Code tasks on a schedule, such as a morning inventory check or a weekly ad review, with catch-up for missed runs, one-time jobs and Slack alerts when a run fails.

Playwright

Lets your agent drive a real, visible Chrome window. Log in once and it can work through websites for you while you watch or take over. Only want the browser? Install the Playwright MCP on its own.

Google Workspace

Gmail, Calendar, Drive, Sheets, Docs and Slides across multiple Google accounts. Draft supplier emails, update a reorder sheet, build a report deck.

Slack

Post and read messages so your agent can send you a daily summary or alert your team when something needs attention.

Lazy Hub

Loads all the other MCP servers through one connection and reloads them without restarting your editor.

Slash Commands

/grill-me interviews you to capture what you know, /handoff-session passes work to a fresh session, and /test-like-human checks results in a real browser.

Also included: Jira, Linear, Notion, Stripe (read-only) and OpenRouter MCP servers, plus the /orchestrate-via-fable and /critical-review commands.

Add Your Amazon Data

Pair It With the Seller Labs MCP Server

The toolbox handles the doing: scheduling, browsing, email, spreadsheets and alerts. It does not include your Amazon data.

The Seller Labs MCP Server connects Claude to your live Seller Central data, including orders, inventory, advertising and profit. Connect both and your scheduled tasks can work from your real numbers.
