Overview

What is AWS Service Reference MCP Server?

The AWS Service Reference MCP Server provides tools to query the AWS Programmatic Service Reference. It enables users to list AWS services, retrieve API actions for a service, and inspect condition keys, resource types, and action properties (e.g., whether an action is a write or list operation). It is aimed at developers and administrators working with AWS IAM policies or service documentation.

How to use AWS Service Reference MCP Server?

Install Python 3.10 or higher, clone the repository, and install dependencies with pip install -r requirements.txt. Run the server directly with python aws_service_reference.py. For use with Claude Desktop, add the server configuration to claude_desktop_config.json using an absolute path to aws_service_reference.py. Once connected, ask Claude natural language questions about AWS services and API actions.

Key features of AWS Service Reference MCP Server

  • Lists all available AWS services
  • Retrieves API actions for a specific service
  • Gets condition keys supported by an API action
  • Gets resource types supported by an API action
  • Gets action properties (write, list, permission management, etc.)

Use cases of AWS Service Reference MCP Server

  • Exploring which AWS services exist and their available API actions
  • Checking condition keys and resource types for an IAM policy statement
  • Distinguishing write operations from read-only operations when building policies
  • Understanding permission management actions that require careful access control
  • Identifying actions that only modify tags (tagging-only operations)

4

How can I troubleshoot connection issues?

Verify that Python 3.10+ is installed and all dependencies are installed (`pip install -r requirements.txt`). Check the Claude Desktop logs at `~/Library/Logs/Claude/mcp*.log` (macOS) or `%APPDATA%\Claude\logs\mcp*.log` (Windows). Ensure the path in the configuration is absolute.

5

What tools does the server provide?

The server exposes five tools: `list_aws_services`, `get_service_actions`, `get_action_condition_keys`, `get_action_resource_types`, and `get_action_properties`.
