wayback-mcp

MCP server for the Internet Archive Wayback Machine: closest snapshots, snapshot history for a URL, and archived page retrieval. Keyless.

Tools

• get_snapshots — List the Wayback Machine snapshot history for a URL, optionally limited to a date range.
• domain_snapshots — List archived pages across a whole domain (every path), not just one exact URL.
• site_history — First and last capture of a URL, plus which years it was archived in.
• get_availability — Check whether a page is archived and get its closest snapshot.
• read_snapshot — Read the text content of an archived page — useful for reading dead or changed sites.
• compare_years — Read the same URL as it looked in several different years, to see how a page changed.
• status_history — One row per archived month with the HTTP status recorded then, so a page that started redirecting or failing can be dated.
• capture_gaps — How much of a period is actually archived for a URL: captured months, missing months, coverage percent and the longest gap.
• snapshot_diff — Compare the same page in two archived years and list the wording that appeared and the wording that vanished.
• broken_pages — Archived captures across a domain that were not HTTP 200 - redirects and dead pages, which is what link rot looks like.

Premium tools

These tools need a licence key:

• content_profile

The tool bodies run on our gateway, not inside this package, so the key is what buys access. Buy one at https://buy.polar.sh/polar_cl_mrO7rS5LZxpqM7oAFFEA10i9121J240U40IIj4JRZO4 and set it in your MCP client config:

"env": { "MCP_LICENSE_KEY": "polar_..." }

The gateway checks the key against Polar and gives every key 1,000 free premium calls a month before per-call billing starts. Every other tool on this server stays free.
