Commoncrawl MCP

The Commoncrawl MCP server provides access to Common Crawl's public web archive, allowing agents to list monthly crawl collections, search CDX indexes for archived captures of URLs or domains, and fetch specific WARC record bytes. It enables historical web data retrieval and verification without requiring direct API keys for the underlying archive.
