1. Find your config file:

   • Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Open it in any text editor and add this (replace your-token with your actual API token):

Mac/Linux:

{
  "mcpServers": {
    "productplan": {
      "command": "/usr/local/bin/productplan",
      "env": {
        "PRODUCTPLAN_API_TOKEN": "your-token"
      }
    }
  }
}

Windows:

{
  "mcpServers": {
    "productplan": {
      "command": "C:\\Tools\\productplan.exe",
      "env": {
        "PRODUCTPLAN_API_TOKEN": "your-token"
      }
    }
  }
}

3. Restart Claude Desktop

Add to your config file:

• Mac/Linux: ~/.claude.json
• Windows: %USERPROFILE%\.claude.json

Mac/Linux:

{
  "mcpServers": {
    "productplan": {
      "command": "/usr/local/bin/productplan",
      "env": {
        "PRODUCTPLAN_API_TOKEN": "your-token"
      }
    }
  }
}

Windows:

{
  "mcpServers": {
    "productplan": {
      "command": "C:\\Tools\\productplan.exe",
      "env": {
        "PRODUCTPLAN_API_TOKEN": "your-token"
      }
    }
  }
}

1. Open Cursor
2. Go to Settings → MCP Servers
3. Add this configuration:

Mac/Linux:

{
  "productplan": {
    "command": "/usr/local/bin/productplan",
    "env": {
      "PRODUCTPLAN_API_TOKEN": "your-token"
    }
  }
}

Windows:

{
  "productplan": {
    "command": "C:\\Tools\\productplan.exe",
    "env": {
      "PRODUCTPLAN_API_TOKEN": "your-token"
    }
  }
}

Windows users: Use double backslashes (\\) in the path. This is required because backslash is an escape character in JSON.

1. Install the Cline extension
2. Open VS Code settings (JSON) and add:

Mac/Linux:

{
  "cline.mcpServers": {
    "productplan": {
      "command": "/usr/local/bin/productplan",
      "env": {
        "PRODUCTPLAN_API_TOKEN": "your-token"
      }
    }
  }
}

Windows:

{
  "cline.mcpServers": {
    "productplan": {
      "command": "C:\\Tools\\productplan.exe",
      "env": {
        "PRODUCTPLAN_API_TOKEN": "your-token"
      }
    }
  }
}

1. Install the Continue extension
2. Add to your config file:
   • Mac/Linux: ~/.continue/config.json
   • Windows: %USERPROFILE%\.continue\config.json

Mac/Linux:

{
  "mcpServers": [
    {
      "name": "productplan",
      "command": "/usr/local/bin/productplan",
      "env": {
        "PRODUCTPLAN_API_TOKEN": "your-token"
      }
    }
  ]
}

Windows:

{
  "mcpServers": [
    {
      "name": "productplan",
      "command": "C:\\Tools\\productplan.exe",
      "env": {
        "PRODUCTPLAN_API_TOKEN": "your-token"
      }
    }
  ]
}

1. Set environment variable on your n8n instance:

   N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE=true
   

2. Add an MCP Client node to your workflow
3. Configure:
   • Command:
     • Mac/Linux: /usr/local/bin/productplan
     • Windows: C:\Tools\productplan.exe
   • Environment Variables: PRODUCTPLAN_API_TOKEN=your-token
4. Connect to an AI Agent node

Example workflow: Slack Trigger → AI Agent (with MCP Client) → Slack Response
