@nexus-catalyst/cursor-plugin

Automatic memory for Cursor. Nexus-Catalyst recalls relevant context from your past sessions and makes it available to the model — no manual tool calls.

How it works

Cursor does not expose a per-turn recall hook that can inject context the way Claude Code does, so this plugin installs an always-apply MCP memory rule (rules/nexus-catalyst.mdc) that instructs the model to call NC's recall_context / store_context MCP tools each turn. Recall is therefore MCP-driven rather than hook-injected. See _docs/cursor-support.md.

Prerequisites

• Node.js 18+
• A Nexus-Catalyst account — sign up at nexus-catalyst.com
• A Plugin API key from app.nexus-catalyst.com → Account → API Keys
• The Nexus-Catalyst MCP server configured in Cursor (see the support doc)

Install

npm install -g @nexus-catalyst/cursor-plugin
nc-cursor install

Verify:

nc-cursor status

Commands

nc-cursor install     Install the NC always-apply memory rule
nc-cursor uninstall   Remove the NC rule (nothing else is touched)
nc-cursor status      Show installation state

Configuration

One key works across all NC tool plugins. It is read from NC_PLUGIN_API_KEY or ~/.nexus-catalyst/config.json (shared — set it once with any plugin's set-key).

NC_API_BASE_URL overrides the endpoint (default https://mcp.nexus-catalyst.com).
