Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00624 | $0.00624 |
| Opus 5 | $0.00312 | $0.00312 |
| Sonnet 5 | $0.00125 | $0.00125 |
| Haiku 4.5 | $0.00062 | $0.00062 |
Grade A, and why
mcp-server-shopping CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
86% identical to mcp-server-amazon CLAUDE.md — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Overview
This is an Amazon MCP (Model Context Protocol) Server that enables AI assistants to interact with Amazon services through web scraping. The server uses Puppeteer for browser automation and exposes Amazon functionality through MCP tools.
Development Commands
# Install dependencies (use -D flag for Puppeteer)
npm install -D
# Build TypeScript to JavaScript
npm run build
# Clean mock HTML files
npm run clean
Architecture
Core Components
- MCP Server (
src/index.ts): Defines and exposes tools via the MCP protocol - Amazon Scraper (
src/amazon.ts): Contains all Amazon interaction logic using Puppeteer and Cheerio - Configuration (
src/config.ts): Manages server settings and paths - Browser Utils (
src/utils.ts): Helper functions for Puppeteer browser automation
Key Dependencies
@modelcontextprotocol/sdk: MCP frameworkpuppeteer: Browser automationcheerio: HTML parsingzod: Schema validation
Authentication
The server requires Amazon cookies for authentication:
- Export cookies from browser using a cookie export extension
- Save to
amazonCookies.jsonin project root - Format: Array of cookie objects with standard properties
Important Implementation Details
Browser Automation
- Uses headless Chrome with specific flags to avoid detection
- Implements user agent spoofing
- Handles Amazon's anti-bot measures
Error Handling
- Detects login page redirects and throws authentication errors
- Implements retry logic for network failures
- Provides detailed error messages for debugging
Mock Mode
- Set
USE_MOCK_RESPONSES=truein environment to use mock HTML files - Mock files stored in
mock/directory - Useful for development and testing without hitting Amazon
Logging
- Server logs to
~/Library/Logs/Claude/mcp-server-shopping.log(Mac) or%APPDATA%\Claude\logs\mcp-server-shopping.log(Windows) - Check logs for debugging authentication or scraping issues
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
