Claude Desktop/Web

Last updated: April, 2026

TL;DR Paid plans connect via the Connectors UI in Settings. Free plans on Desktop connect via the mcp-remote config bridge.

Claude supports MCP on both free and paid plans, but the setup paths are different. Use the section that matches your plan.

Prerequisites

• Paid plan path: A Claude paid plan (Pro, Max, Team, or Enterprise). Works on both Desktop and Web.

• Free plan path: Claude Desktop installed (Mac or Windows). Node.js installed. Free plan only works on Desktop, not Web.

Setup — paid plans (Pro, Max, Team, Enterprise)

1. Open Settings → Connectors.

2. Click Add Custom Connector and paste: https://app.plurality.network/mcp

3. Claude opens a browser window for OAuth login. Sign in with your Plurality account.

4. Once authenticated, the Plurality tools appear in the chat input.

Setup — free plan (Desktop only)

Free-plan users can connect the Desktop app via the mcp-remote bridge.

1. Open the Claude Desktop config file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

   • Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add the mcpServers block:

{
  "mcpServers": {
    "plurality-memory": {
      "command": "npx",
      "args": ["mcp-remote", "https://app.plurality.network/mcp"]
    }
  }
}

Windows note: if you see "Connection closed" errors, wrap the command with cmd /c:

{
  "command": "cmd",
  "args": ["/c", "npx", "mcp-remote", "https://app.plurality.network/mcp"]
}

1. Fully restart Claude Desktop — quit and reopen, not just close the window.

2. On first use, mcp-remote opens your browser for OAuth login. After authenticating, tokens are cached locally.

Verify

Look for the connectors icon in Claude's chat input. The Plurality memory connector should appear in the list.

In a new chat, ask: "What's in my Plurality memory?"

If it calls the get_user_memory_buckets tool and returns your buckets, you're connected.

Troubleshoot

Tools don't appear after adding the connector. Fully quit Claude (don't just close the window) and reopen.

Free plan: mcp-remote errors with "Connection closed." On Windows, use the cmd /c wrapper shown above.

Free plan: npx not found. Install Node.js. The mcp-remote bridge requires it.

OAuth completes but tools still missing. Check the URL in your config — no trailing slash, no extra characters should be there.
