Why Flippa MCP

Flippa is the world's largest marketplace for buying and selling online businesses — websites, SaaS products, ecommerce stores, apps, newsletters, and more. Thousands of listings, each with revenue claims, traffic stats, and asking prices that may or may not make sense.

Evaluating a listing manually means checking revenue multiples, comparing prices across similar businesses, assessing risk factors, and doing math you'll probably get wrong at 2am. Multiply that by the dozens of listings you need to review to find a good deal.

Flippa MCP gives Claude full marketplace intelligence. Five specialized tools that search listings, pull detailed financials, compute valuation metrics, find comparable sales, and generate market overviews. Zero configuration. No API key. No Flippa account. Just install and ask Claude to find you a good deal.

Who This Is For

Entrepreneurs evaluating businesses to buy on Flippa
Investors doing due diligence on online business acquisitions
Sellers researching pricing and market conditions before listing
Anyone who wants AI-powered marketplace intelligence without the spreadsheet grind

How Analysis Works

The flippa_analyze_listing tool fetches a listing and computes valuation metrics:

Metric	Formula
Revenue Multiple	Asking Price / Annual Revenue
Profit Multiple	Asking Price / Annual Profit
ROI Estimate	Asking Price / Monthly Profit (payback in months)
Price per Visitor	Asking Price / Monthly Uniques

Verdict Logic

Revenue Multiple	Verdict
< 2x	Underpriced — below typical range, investigate why
2x – 4x	Fair — within standard online business valuation range
> 4x	Overpriced — above typical range, ensure premium is justified
No revenue data	Insufficient Data — cannot determine valuation

Risk Factors Detected

The tool automatically flags these concerns:

No reported revenue or profit
Traffic data unavailable or very low (< 1,000 uniques/mo)
Revenue not verified by Flippa
Traffic not verified by Flippa
Seller is not a Super Seller
No bids on the listing
No images provided
Very short listing description (< 100 chars)
Confidential listing with limited data

Configuration

Variable	Required	Default	Description
`FLIPPA_BASE_URL`	No	`https://flippa.com/v3`	Override the Flippa API base URL
`FLIPPA_API_TOKEN`	No	—	Bearer token for future authenticated endpoints (watchlist, bidding)
