Cursor

Cursor Connector

Bring your AI knowledge into your code editor

Context Companion integrates with Cursor through the Model Context Protocol (MCP), giving Cursor access to your conversation history and knowledge base. Cursor automatically decides when to use this context, so you don't need to mention Context Companion in your questions.

How They Work Together

Step 1

Brainstorm

Have conversations with ChatGPT, Claude, or Gemini about your project ideas, architecture, and decisions.

Before you begin, make sure you have:

  • Context Companion extension installed in your browser
  • Cursor installed on your computer
  • Some conversations saved in Context Companion (so there's context to recall)

Get Your Connector Key

Each user has their own unique connector key for security. You'll get this from the Context Companion extension.

Open Context Companion Extension

Click the Context Companion icon in your browser toolbar.

Navigate to Connectors Tab

Click on the "Connectors" tab and expand the "Cursor" section.

Copy JSON Configuration

Click "Copy JSON Configuration for Cursor" — this includes your key and all required settings.

Configure Cursor

Open Cursor Settings

Press Cmd/Ctrl + Shift + P and type "Open User Settings (JSON)"

Add Configuration

Find or create the "mcpServers" section and paste your configuration inside it.

Restart Cursor

Close and reopen Cursor. Check Settings → Features → MCP to verify Context Companion shows as connected.

Start Using It

Just ask Cursor naturally — it automatically queries Context Companion when relevant:

  • •"What did we decide about the API design?"
  • •"I've been thinking about our dashboard project"
  • •"Remind me what we discussed about authentication"

Frequently Asked Questions

Does Cursor automatically use Context Companion?

Yes! Cursor automatically decides when to query Context Companion based on your questions. You don't need to mention Context Companion explicitly — just ask naturally about past conversations or decisions.

What data does Cursor have access to?

Cursor can only read your summaries through the MCP connection. It cannot modify, delete, or access raw conversation content. Only the summarized knowledge you've captured is available.

Do I need to keep the browser extension running?

No. Cursor connects directly to your Context Companion account via the MCP server. Once configured, it works independently of the browser extension.

Can I use Context Companion with other IDEs?

Currently, Cursor is the only IDE we support via MCP. We're exploring integrations with other MCP-compatible tools in the future.
