Is Memory MCP server safe?

No malicious indicators - review capabilities before installing
Notable — review in context (capabilities are not malware):
  • npm prepare hook

@modelcontextprotocol/server-memory is an AI npm_package analyzed by SkillTotal's deterministic static scanner. The scan found no malicious indicators, though 1 risky construct are reported for review. It can: install time execution — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).

MEDIUMnpm prepare hookST-INSTALL-NPM-PREPARE

package.json has a 'prepare' script (runs on git/local installs and before publishing).

package.json:23-23 
"prepare": "npm run build",

Why it matters: Usually a build step, but confirm it doesn't fetch or run remote code.

Fix: Usually a legitimate build step; confirm it only builds and does not fetch or execute remote code.
