• Inputs — Amazon ASIN (auto-fetched via Shulex VOC OpenAPI, 10 markets) or any review CSV / Excel (Helium 10 / eBay / Shopify / custom — fuzzy column detection)
• Outputs — Markdown report · structured JSON · standalone HTML dashboard
• Surface — MCP server (works in Claude Code / Cursor / Cline / Continue) and Skill (works in Claude Code)

Quick start

Option A — As an MCP server (recommended)

Requires uv.

Add this to your MCP client config (Claude Code, Claude Desktop, Cursor, Windsurf, VS Code Copilot, Cline, Continue.dev):

{
  "mcpServers": {
    "voc-amazon-reviews": {
      "command": "uvx",
      "args": ["voc-amazon-reviews-mcp"],
      "env": {
        "VOC_API_KEY": "your-shulex-key"
      }
    }
  }
}

Get a free Shulex API key (100 calls/month, no credit card): apps.voc.ai/openapi.

Optional: Add "ANTHROPIC_API_KEY": "sk-ant-..." to enable extract_listing_improvements (the only tool that calls Claude directly — others work without it). Must be an actual Anthropic key; other providers won't work.

First run resolves dependencies in ~5s; subsequent runs are instant.

Try it

Ask any MCP-compatible agent:

Run a VOC report on B08N5WRWNW, render the dashboard, and write it to ~/Desktop/voc.html.

The agent will call voc_full → render_dashboard and hand you the file.
