Installation

Cursor	VS Code
Configure the MCP server in your MCP client configuration (e.g., for Amazon Q Developer CLI, edit ~/.aws/amazonq/mcp.json):

{
      "mcpServers": {
            "awslabs.amazon-qbusiness-anonymous-mcp-server": {
                  "command": "uvx",
                  "args": ["awslabs.qbusiness-anonymous-mcp-server"],
                  "env": {
                    "FASTMCP_LOG_LEVEL": "ERROR",
                    "QBUSINESS_APPLICATION_ID": "[Your Amazon Q Business application id]",
                    "AWS_PROFILE": "[Your AWS Profile Name]",
                    "AWS_REGION": "[Region where your Amazon Q Business application resides]"
                  },
                  "disabled": false,
                  "autoApprove": []
                }
      }
}

or docker after a successful docker build -t awslabs/amazon-kendra-index-mcp-server.:

# fictitious `.env` file with AWS temporary credentials
AWS_ACCESS_KEY_ID=<from the profile you set up>
AWS_SECRET_ACCESS_KEY=<from the profile you set up>
AWS_SESSION_TOKEN=<from the profile you set up>

  {
    "mcpServers": {
      "awslabs.amazon-qbusiness-anonymous-mcp-server": {
        "command": "docker",
        "args": [
          "run",
          "--rm",
          "--interactive",
          "--env-file",
          "/full/path/to/file/above/.env",
          "awslabs/amazon-qbusiness-anonymous-mcp-server:latest"
        ],

Best Practices

• Follow the principle of least privilege when setting up IAM permissions
• Use separate AWS profiles for different environments (dev, test, prod)
• Monitor broker metrics and logs for performance and issues
• Implement proper error handling in your client applications

Security Considerations

When using this MCP server, consider:

• This MCP server needs permissions to use conversation APIs with your Amazon Q Business application created in anonymous mode.
• This MCP server cannot create, modify, or delete resources in your account

Troubleshooting

• If you encounter permission errors, verify your IAM user has the correct policies attached
• For connection issues, check network configurations and security groups
• If resource modification fails with a tag validation error, it means the resource was not created by the MCP server
• For general Amazon Q Business issues, consult the Amazon Q Business user guide
