Install pail in Cursor

Get pail's MCP server connected to Cursor in under two minutes. The server exposes all 10 tools; plan gates still apply, including Pro access for preview.

Prerequisites

• Cursor 0.46 or later
• A pail account at pail.thalos.ai (free tier is fine)
• Your API key from the welcome page after sign-in

Install

Add this to .cursor/mcp.json in your project root (or create the file if it doesn't exist). Replace YOUR_API_KEY with the key from your pail welcome page.

{
  "mcpServers": {
    "pail": {
      "url": "https://pail.thalos.ai/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

Verify installation

Open Cursor Settings → MCP. pail should appear in the server list with a green connected status.

# Open Cursor Settings → MCP

First share

With pail connected, ask your agent to share a file. This verifies that the tool is reachable and your API key is working.

# In Cursor chat, ask your agent:
share a file called hello.md with the content "# Hello from pail!"

The agent calls the share tool and returns a URL. Open it in your browser to see the rendered Markdown.
