MCP servers for search and extraction
Web search, crawling and scraping servers for retrieval pipelines. If your agent needs current information rather than training data, this is the layer that provides it.
How this list was ordered. There is no reliable popularity signal in the source registries, so entries are ranked by how completely the record is documented — a substantial description plus a documentation, repository or base URL — and then alphabetically. 278 mcp servers in this scope clear the content bar; the top 24 are shown. A place here is not an endorsement or a paid slot.

FieldmodeLLC/scrapecheck-mcp
Verify scraped data against the live source page: send a URL, the scraped field values, and what was asked, and get back an ed25519-signed verdict (pass, fail, or unverifiable).
