Best MCP servers for code search and navigation

We found 147 MCP servers for code search and navigation in the catalog; these are the 15 that rank highest. The order comes from our rank, which weighs adoption, freshness, documentation and publisher identity. Nobody can pay for a place on this list. jCodemunch MCP, Benzi and Hex Graph lead it. Sem has the most GitHub stars here (3,422). 14 of the 15 had activity in the last 30 days. Remote servers need no local install; local ones run on your machine and can reach local files. Each entry lists why it made the list and links to its install page.
