Cursor + MemorySync

Overview

Install the MemorySync plugin and Cursor remembers: lifecycle hooks persist every prompt and reply the moment they happen (with idempotency seeds that make double-fired events converge), a compact always-on rule keeps the agent recalling through the MemorySync MCP tools, and memory is auto-scoped to the git repository. Cursor hooks cannot inject model context — the honest architecture is hook-automatic capture plus rule-driven recall — and every hook answers {"continue": true} on every path, so memory can never block or break a session. Also installable MCP-only via a one-click deeplink or npx memorysync-mcp-install.

Setup status and requirements

Supported version

memorysync Cursor plugin 1.1.0

Last setup review

2026-08-23

Permissions

A MemorySync API key with read and write scopes (or OAuth through the MCP server).

Limits

Full plugin requires a Cursor build with plugins + hooks and Node.js 18+ on PATH. Cursor hooks cannot inject context, so recall is rule + tool driven.

Capabilities

• Automatic capture: every exchange persisted by hooks, not model discretion
• Always-on recall rule steering the agent through the MCP tools
• Per-repo project scoping from the git remote, worktree-aware
• Cross-platform Node hooks — native Windows, macOS, Linux
• Incapable of breaking a session: {"continue": true} on every path, tested
• One-click "Add to Cursor" deeplink and npx MCP-only installs
• Same skills and MCP tools as the Claude Code and Codex plugins

Quick Start

# MCP in one command:
npx memorysync-mcp-install --client cursor

# Full plugin (hooks + rule + skills): copy plugins/memorysync from
# github.com/Rafay121/memorysync-plugins into
# ~/.cursor/plugins/local/memorysync, then "Developer: Reload Window".
