Cursor

Overview

Cursor supports MCP servers natively, which means Rekall integrates seamlessly into your coding workflow. Once configured, Cursor's AI assistant can store and recall memories about your projects, coding decisions, architecture patterns, and team conventions.

Installation

First, install the Rekall MCP server globally:

npm install -g @rekall/mcp-server

Optionally, install the Rekall Cursor plugin for enhanced features like inline memory hints and project-aware context:

# Install via Cursor Extensions
# 1. Open Cursor
# 2. Go to Extensions (Cmd+Shift+X / Ctrl+Shift+X)
# 3. Search for "Rekall"
# 4. Click Install

MCP Configuration

Configure the MCP server in Cursor's settings. Open Cursor Settings and navigate to the MCP section, or edit the configuration file directly:

1. Open Cursor Settings (Cmd+, / Ctrl+,)
2. Navigate to "Features" > "MCP Servers"
3. Click "Add Server"
4. Enter the following:
   - Name: rekall
   - Command: rekall-mcp
   - Args: --stdio
5. Add environment variable:
   - REKALL_API_KEY: your-api-key-here
6. Click Save

Project-Aware Memory

Rekall automatically scopes memories to your current project when configured with a project context. This means memories from one project do not bleed into another, keeping each codebase's context clean and relevant.

// .rekallrc in your project root
{
  "context": "my-saas-app",
  "agentId": "cursor",
  "autoCapture": {
    "decisions": true,
    "patterns": true,
    "errors": false
  },
  "hive": "frontend-team"
}

When autoCapture is enabled, Cursor automatically stores significant coding decisions and detected patterns as memories. This happens in the background without interrupting your workflow.

Using Memory in Cursor

Rekall memory is accessible in all of Cursor's AI interaction modes:

Memory in Chat

In Cursor's Chat panel, the AI assistant automatically has access to Rekall tools. You can ask it to remember or recall information naturally:

You: "Remember that we use Zod for all API input validation in this project."

Cursor: "I've stored that as a semantic memory: your project uses Zod for
API input validation. I'll keep this in mind for future code suggestions."

---

You: "What validation library do we use?"

Cursor: "Based on my memory, this project uses Zod for all API input
validation."

Memory in Composer

When using Cursor Composer for multi-file edits, the AI can recall project conventions and patterns to generate consistent code:

You: "Create a new API endpoint for user preferences."

Cursor: [Recalls project patterns from memory]
"Based on your project conventions, I'll create the endpoint using:
- Express with TypeScript
- Zod for input validation
- The repository pattern you use for data access
- Error handling consistent with your existing endpoints"

[Generates code matching your established patterns]

Inline Memory

With the Rekall Cursor plugin installed, you get inline memory hints. When editing code in areas where relevant memories exist, a subtle indicator appears in the gutter showing available context:
