Only enable these flags when necessary and in trusted environments. + + +## Quickstart + +This quickstart guide walks you through the steps to configure the Amazon Data Processing MCP Server for use with both the [Cursor](https://www.cursor.com/en/downloads) IDE and the [Amazon Q Developer CLI](https://github.com/aws/amazon-q-developer-cli). By following these steps, you'll setup your development environment to leverage the Data Processing MCP Server's tools for managing your Glue, EMR and Athena resources. + +**Set up Cursor** + +1. Open Cursor. +2. Click the gear icon (⚙️) in the top right to open the settings panel, click **MCP**, **Add new global MCP server**. +3. Paste your MCP server definition. For example, this example shows how to configure the Data Processing MCP Server, including enabling mutating actions by adding the `--allow-write` flag to the server arguments: + +``` +{ + "mcpServers": { + "aws.dataprocessing-mcp-server": { + "autoApprove": [], + "disabled": false, + "command": "uvx", + "args": [ + "aws.dataprocessing-mcp-server@latest", + "--allow-write" + ], + "env": { + "FASTMCP_LOG_LEVEL": "ERROR", + "AWS_REGION": "us-east-1" + }, + "transportType": "stdio" + } + } +} +``` +After a few minutes, you should see a green indicator if your MCP server definition is valid. + +4. Open a chat panel in Cursor (e.g., `Ctrl/⌘ + L`). In your Cursor chat window, enter your prompt. For example, "Look at all the tables from my account federated across GDC" + +**Set up the Amazon Q Developer CLI** + +1. Install the [Amazon Q Developer CLI](https://docs.aws.amazon.com/amazonq/latest/qdeveloper-ug/command-line-installing.html) . +2. The Q Developer CLI supports MCP servers for tools and prompts out-of-the-box. Edit your Q developer CLI's MCP configuration file named mcp.json following [these instructions](https://docs.aws.amazon.com/amazonq/latest/qdeveloper-ug/command-line-mcp-configuration.html). For example: + +``` +{ + "mcpServers": { + "aws.dataprocessing-mcp-server": { + "command": "uvx", + "args": ["aws.dataprocessing-mcp-server@latest"], + "env": { + "FASTMCP_LOG_LEVEL": "ERROR" + }, + "autoApprove": [], + "disabled": false + } + } +} +``` + +3. Verify your setup by running the `/tools` command in the Q Developer CLI to see the available Data Processing MCP tools. + +Note that this is a basic quickstart. You can enable additional capabilities, such as [running MCP servers in containers](https://github.com/awslabs/mcp?tab=readme-ov-file#running-mcp-servers-in-containers) or combining more MCP servers like the [AWS Documentation MCP Server](https://awslabs.github.io/mcp/servers/aws-documentation-mcp-server/) into a single MCP server definition. To view an example, see the [Installation and Setup](https://github.com/awslabs/mcp?tab=readme-ov-file#installation-and-setup) guide in AWS MCP Servers on GitHub. To view a real-world implementation with application code in context with an MCP server, see the [Server Developer](https://modelcontextprotocol.io/quickstart/server) guide in Anthropic documentation. + +## Configurations + +### Arguments + +The `args` field in the MCP server definition specifies the command-line arguments passed to the server when it starts. These arguments control how the server is executed and configured. For example: + +``` +{ + "mcpServers": { + "awslabs.dataprocessing-mcp-server": { + "command": "uvx", + "args": [ + "aws.dataprocessing-mcp-server@latest", + "--allow-write", + "--allow-sensitive-data-access" + ], + "env": { + "AWS_PROFILE": "your-profile", + "AWS_REGION": "us-east-1" + } + } + } +} +``` + +#### `awslabs.dataprocessing-mcp-server@latest` (required) + +Specifies the latest package/version specifier for the MCP client config. + +* Enables MCP server startup and tool registration. + +#### `--allow-write` (optional) + +Enables write access mode, which allows mutating operations (e.g., create, update, delete resources) + +* Default: false (The server runs in read-only mode by default) +* Example: Add `--allow-write` to the `args` list in your MCP server definition. + +#### `--allow-sensitive-data-access` (optional) + +Enables access to sensitive data such as logs, events, and Kubernetes Secrets. + +* Default: false (Access to sensitive data is restricted by default) +* Example: Add `--allow-sensitive-data-access` to the `args` list in your MCP server definition. + +### Environment variables + +The `env` field in the MCP server definition allows you to configure environment variables that control the behavior of the DataProcessing MCP server. For example: + +``` +{ + "mcpServers": { + "awslabs.dataprocessing-mcp-server": { + "env": { + "FASTMCP_LOG_LEVEL": "ERROR", + "AWS_PROFILE": "my-profile", + "AWS_REGION": "us-west-2" + } + } + } +} +``` + +#### `FASTMCP_LOG_LEVEL` (optional) + +Sets the logging level verbosity for the server. + +* Valid values: "DEBUG", "INFO", "WARNING", "ERROR", "CRITICAL" +* Default: "WARNING" +* Example: `"FASTMCP_LOG_LEVEL": "ERROR"` + +#### `AWS_PROFILE` (optional) + +Specifies the AWS profile to use for authentication. + +* Default: None (If not set, uses default AWS credentials). +* Example: `"AWS_PROFILE": "my-profile"` + +#### `AWS_REGION` (optional) + +Specifies the AWS region where Glue,EMR clusters or Athena are managed, which will be used for all AWS service operations. + +* Default: None (If not set, uses default AWS region). +* Example: `"AWS_REGION": "us-west-2"` + +## Tools + +### Glue Data Catalog Handler Tools + +| Tool Name | Description | Key Operations |
