1. Connect the MCP server
LiftArchive runs a free, read-only MCP server at https://liftarchive.com/mcp/.
Claude: Settings → Connectors → Add custom connector, then paste the URL.
ChatGPT: Settings → Apps & Connectors → Advanced → turn on Developer mode, then create a connector with the URL.
Cursor, Claude Code and other MCP clients: add a remote (HTTP) MCP server with the same URL.
2. Ask it things
- “Suggest A/B tests for https://mystore.com/products/best-seller.”
- “Show me checkout tests that won, with numbers.”
- “What happened when SaaS companies tested their pricing page?”
- “Which paywall tests worked for subscription apps?”
- “Find a CRO expert for a Shopify store.”
3. The tools it has
- search_tests: by text, vertical, page type, element and outcome.
- get_test: the full record of one test.
- list_facets: what's in the database, with counts.
- suggest_tests_for_site: looks at a page and suggests the best-proven tests for what it's missing.
- find_expert: experts who share their results publicly, with booking links.
Prefer raw data?
llms.txt describes the site for AI tools, and /data/tests.json has every test as structured data.
Results belong to the people who ran them: when you use one, credit them by name and link to the LiftArchive page.
