Keepa MCP Server

A Model Context Protocol (MCP) server that gives Claude access to Keepa's product and sales data through a more approachable, conversational interface. It simplifies Keepa's complex, engineer-oriented design, making it easier to explore product research, sales trends, inventory signals, and competitive analytics without needing to master Keepa's native UI.

Node.js: Version 18 or higher

Installation

Clone or download this repository
Navigate to the project directory:
```
cd keepa_mcp
```
Install dependencies:
```
npm install
```
Build the TypeScript code:
```
npm run build
```
You'll configure your Keepa API key in the Claude Desktop config (next section)

Configuration

Environment Variables

The MCP server accepts these environment variables (configured in Claude Desktop):

KEEPA_API_KEY (required): Your Keepa API key
KEEPA_RATE_LIMIT_DELAY (optional): Delay between requests in milliseconds (default: 1000)
KEEPA_TIMEOUT (optional): Request timeout in milliseconds (default: 30000)

Claude Desktop Configuration

Location:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%/Claude/claude_desktop_config.json

Note: If the file doesn't exist, create it. Some installations may have config.json instead - copy it to the correct filename:

cp ~/Library/Application\ Support/Claude/config.json ~/Library/Application\ Support/Claude/claude_desktop_config.json

Add to your Claude Desktop claude_desktop_config.json:

{
  "mcpServers": {
    "keepa": {
      "command": "node",
      "args": ["/path/to/keepa_mcp/dist/index.js"],
      "env": {
        "KEEPA_API_KEY": "your_keepa_api_key_here"
      }
    }
  }
}

Replace /path/to/keepa_mcp with your actual path and your_keepa_api_key_here with your Keepa API key.

⚠️ Important: After making any changes to your claude_desktop_config.json file, you must completely close Claude Desktop (Cmd+Q on macOS or Alt+F4 on Windows) and restart it for the changes to take effect.

Grant MCP Server Permissions

When you first start Claude Desktop with the MCP server configured, you'll see a permission dialog. Click "Allow" to grant the server access as needed:

You must grant these permissions for the Keepa tools to appear and function properly.

🔧 Troubleshooting

If MCP tools don't appear in Claude Desktop:

Check Claude Desktop version: Ensure you're running version 0.7.0 or later (MCP support required)
- Click "Claude" menu → "About Claude"

Verify config file location and format:

# Check if file exists
ls -la ~/Library/Application\ Support/Claude/claude_desktop_config.json

# Validate JSON format
cat ~/Library/Application\ Support/Claude/claude_desktop_config.json

Test MCP server manually:

cd /path/to/keepa_mcp
npm run build
KEEPA_API_KEY=your_key_here node dist/index.js

Complete restart: Force quit Claude Desktop (Cmd+Q) and relaunch

Simplified config: Try removing other settings and use minimal config:

{
  "mcpServers": {
    "keepa": {
      "command": "node",
      "args": ["/full/path/to/keepa_mcp/dist/index.js"],
      "env": {
        "KEEPA_API_KEY": "your_keepa_api_key_here"
      }
    }
  }
}

Check for logs: Look for error messages in Claude Desktop console or system logs

Common Issues:

Wrong file path: Ensure the path to dist/index.js is absolute and correct
Missing build: Run npm run build after any code changes
Invalid JSON: Use a JSON validator to check config file syntax
Missing API key: Make sure KEEPA_API_KEY is set in the env section of your config

💬 Simple Usage: Just mention the country: "Find deals in German Amazon using Keepa"

💰 Token Usage & Cost Information

The Keepa API operates on a token-based system where each API query consumes tokens from your account. Different endpoints consume different amounts of tokens, and your usage is tracked across all requests.

📊 Token Usage Guidelines

Product Lookup: ~1 token (includes Statistics Object data at no additional cost)
Market Analysis: ~5-15 tokens (depending on category size)
Deal Discovery: ~3-8 tokens (varies by filters)
Velocity Analysis: ~2-5 tokens (includes portfolio metrics)

💡 Cost Optimization Features

Statistics Object Integration: Sales velocity and inventory analytics included with product lookups (no additional tokens required)
Smart Batching: Process up to 100 ASINs in single requests to minimize token usage
Efficient Caching: Built-in rate limiting and request optimization

⚠️ IMPORTANT: Token Exhaustion Behavior

Critical Limitation: When your Keepa API tokens are exhausted (≤0), the MCP server will fail and return "No products found" messages instead of meaningful data.

What Happens:

❌ Searches return empty results (not actual empty categories)
❌ No error indicating token exhaustion (appears as failed searches)
❌ All tools appear broken until tokens refresh

How to Identify:

Use the dedicated token status tool: Ask Claude "Check my Keepa token status"
Multiple categories returning "No products found"
Recently working searches suddenly failing
Low token warnings in search results

Solutions:

Wait for token refresh (daily or monthly depending on your Keepa plan)
Upgrade your Keepa plan for more tokens
Check your usage at Keepa API Dashboard

Low Token Warning: The server warns when you have <5 tokens remaining.
