Semgrep is an MCP server published by docker. Marketplaces we read that list it: 1 (Docker MCP Catalog). jgrep is a plugin bundle for AI coding tools published by kyu1204. Marketplaces we read that list it: 1 (Community GitHub marketplaces). As of our marketplace pass on 2026-11-08. This pair was picked by a reader, not by our comparison rule, so search engines are asked not to index the page.

Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
