Cursor

Last updated: April, 2026

TL;DR Edit one JSON file, restart Cursor, OAuth on first use.

Prerequisites

• Cursor installed

Setup

Cursor supports global config (all projects) or project-level config.

Global setup. Edit ~/.cursor/mcp.json (create the file if it doesn't exist):

{
  "mcpServers": {
    "plurality-memory": {
      "url": "https://app.plurality.network/mcp"
    }
  }
}

Project-level setup. Create .cursor/mcp.json in your project root with the same content.

After saving the config, fully restart Cursor (quit and reopen, not just close the window).

Verify

Navigate to Settings → MCP. The plurality-memory server should show a green active status.

On first use, Cursor opens your browser to complete OAuth. After authentication, the tools are available in your chat input.

Troubleshoot

Server shows red / inactive in Settings → MCP. Check the JSON — most issues are typos or missing commas. Confirm the URL is exactly https://app.plurality.network/mcp.

OAuth never opens. Try sending a chat message — Cursor triggers OAuth lazily on first tool call.

Tools work in one project but not another. You added project-level config in one and not the other. Move the config to ~/.cursor/mcp.json for global access.
