Best MCP servers for knowledge graphs

We found 161 MCP servers for knowledge graphs 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. Codebase Memory, Google Surf MCP and Shodh Memory lead it. RoboSystems is published by the company that makes it. Codebase Memory has the most GitHub stars here (47,374). 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.
