# Wayback Machine

> Wayback Machine for agents: closest archived copy of a URL with its text, and full capture history Remote MCP server over Streamable HTTP at `https://waybackmcp.com/mcp`. Free, no API key. Tools: `archived_copy`, `capture_history`. The tool list is fixed per version.

Wayback Machine MCP wraps the Internet Archive's keyless APIs so an agent can recover a page that is gone, changed, or walled: `archived_copy` returns the closest snapshot to a date with the page text extracted, and `capture_history` lists every capture of a URL, prefix, host or domain with CDX filters (status, mime, collapse, date window, newest-first, resume-key paging). Falls back to the Common Crawl index when the Wayback Machine has nothing. Free, no API key, no account.

Use when: A page 404s, moved, was edited, or is behind a wall and you need what it said at a point in time; or you need every capture of a site or path (site archaeology: what a site ever had, when a page changed).

Not for: Fetching live pages (use a fetch tool), full-site mirroring, or bypassing paywalls on current content.
