knowledge graphs MCP servers: questions people ask
What's the most popular MCP server for knowledge graphs?
mcp-neo4j-memory is published by the company behind knowledge graphs, which makes it the safest first pick. On GitHub stars, FastMCP server for surgical queries against a vault knowledge graph (NetworkX no (★ 3), fish-bridge — Session Knowledge Graph (★ 2) and Fodda Knowledge Graphs (★ 1) lead the 101 we list. FastMCP server for surgical queries against a vault knowledge graph (NetworkX no is named for knowledge graphs and passed every check we run.
Are knowledge graphs MCP servers safe to install?
79 of the 101 passed every registry check. Reading the package code or tool descriptions of 74 of them turned up 15 with something to look at, from install scripts to obfuscated code. A clean result means none of our patterns matched, not that a server is safe.
Hosted or local: how do knowledge graphs MCP servers run?
26 can run hosted, so you only paste a URL into Claude, Cursor or VS Code. The 78 that run locally ship as 36 npm, 27 PyPI, 8 Docker, 3 MCPB bundle and 1 Cargo packages.
Are knowledge graphs MCP servers kept up to date?
36 of the 101 were updated in the 30 days before 31 Oct 2026. The latest was KG-SSOT, on 28 October.
Is there an official knowledge graphs MCP server?
Yes. mcp-neo4j-memory is published under a namespace the official MCP Registry verified to the company. The other 100 come from 97 independent publishers.
