What AWS MCP Servers (awslabs/mcp) is

The README notes that the Agent Toolkit for AWS is the successor and that this repo continues to work and accept contributions.

Where AWS MCP Servers (awslabs/mcp) runs and what it adds, from its documentation
  • Ships many separate MCP servers (documentation, API, IaC, pricing, support, Bedrock, data and analytics, healthcare and life sciences)
  • AWS API MCP Server runs AWS CLI commands with validation and security controls
  • AWS Documentation MCP Server fetches and searches current AWS docs
  • AWS IaC MCP Server covers CloudFormation docs, CDK guidance and security validation
  • Provides an MCP AWS Lambda handler module for building your own servers

When to use it

Good fit

  • You want an AI assistant to read current AWS docs and API references
  • You want natural-language AWS operations or IaC help from your coding agent
  • You want to pick only the AWS servers relevant to one workload

Not for

  • Remote or HTTP transport: the servers are designed to support stdio only
  • New production work where AWS recommends the Agent Toolkit for AWS instead (per README tip)

How to install AWS MCP Servers (awslabs/mcp)

You need: uv and Python 3.10 or newer; AWS account and configured credentials for most servers

  1. Install uv from Astral and Python 3.10+
  2. Configure AWS credentials for the services you need
  3. Add the server entry to your MCP client config (see config_example)
  4. Claude Code: claude mcp add aws-docs uvx awslabs.aws-documentation-mcp-server@latest
  5. Restart the client and see each server's own README for specific requirements
Configuration example (from the official docs)
{
  "mcpServers": {
    "awslabs-core-mcp-server": {
      "command": "uvx",
      "args": [
        "awslabs.core-mcp-server@latest"

        "FASTMCP_LOG_LEVEL": "ERROR"
      }
    }
  }
}

Permissions and security

What it can access

  • Depends on the server and the AWS credentials you give it; the API server can run AWS CLI commands

Security notes from the maintainers

  • README says you are responsible for compliance with the terms governing use of these servers

Review the source before granting an agent access to credentials or production systems. We document what the maintainers state; we do not audit code.

Limitations

  • Servers support stdio only; SSE support was removed on May 26, 2025
  • Streamable HTTP support is still being worked on
  • README says useful projects will over time move into Agent Toolkit for AWS
