LazyInvestor/fauxgen-mcp

Fake data for agents.
MCP server that gives Cursor, Claude, Windsurf & friends instant fictional identities,
addresses, phones, Luhn test cards and more — powered by the same idea as
fauxgen.com .
## Why
Agents write forms, seeds and Playwright fixtures all day. They shouldn't invent SSNs from thin air or paste the same John Doe forever.
You: seed a German checkout user
Agent: → generateidentity({ country: "de" })
→ valid-looking DE address, phone, IBAN-ready country, test Visa…
## Install (30 seconds)

### Claude Desktop
~/Library/Application Support/Claude/claudedesktopconfig.json (macOS):

## Safety
All output is fictional test data. Do not use it to deceive people, open real accounts, or commit fraud. Test cards and IBANs pass checksums so your validators work — they are not real payment instruments.
