A side-by-side look at the Vault Cortex and XNotepad AI MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Vault Cortex for knowledge & memory work as a local process; choose XNotepad AI for knowledge & memory. You can also run both side by side in one mcpServers block.
MCP_AUTH_TOKEN, VAULT_PATH.Rows where the two servers differ are marked.
