If you’re building AI agents that need to interact with AWS infrastructure, you’ve faced the same uncomfortable question: how do you give an agent real, authenticated access to AWS without handing it unrestricted credentials? As of May 6, 2026, AWS has an official answer: the AWS MCP Server, now generally available.

What Is the AWS MCP Server?

The AWS MCP Server is a managed, remote Model Context Protocol (MCP) server that gives AI agents and coding assistants secure, authenticated access to AWS services through a small, fixed set of well-defined tools.

Instead of building your own AWS integration layer for every agent, you configure the agent to connect to the AWS MCP Server endpoint and authenticate with IAM credentials. The server handles the translation between MCP tool calls and AWS API calls — covering services including EC2, S3, CloudWatch, CloudTrail, and more.

According to the official AWS announcement:

  • Available in US East (N. Virginia) and Europe (Frankfurt)
  • No additional charge — pay only for the underlying AWS resources used
  • Part of the broader Agent Toolkit for AWS

The Agent Toolkit for AWS

The AWS MCP Server ships as part of a larger suite called the Agent Toolkit for AWS, which includes three components:

Agent Skills

Curated standard operating procedures (SOPs) — pre-built templates for common AWS agent workflows. Instead of writing custom instructions for every task, Agent Skills gives your agent a library of tested patterns to draw from.

Agent Plugins

One-click install bundles that add specific AWS capabilities to your coding agent. These are designed to get you from zero to a functional AWS-integrated agent quickly, without manual configuration.

Guardrails

Security and policy controls built into the toolkit. Guardrails let you define what the agent can and cannot do within your AWS environment — enforcing least-privilege principles even for AI-driven actions.

Getting Connected: What You Need

To connect an AI agent or coding assistant to the AWS MCP Server, you’ll need:

  1. IAM credentials configured with appropriate permissions for the services you want the agent to access
  2. An MCP-compatible agent or client — the AWS MCP Server is compatible with tools that support remote MCP endpoints (the protocol is open standard)
  3. The MCP Server endpoint — the confirmed endpoint is aws-mcp.us-east-1.api.aws/mcp (US East region)

Note: For the latest setup instructions, IAM permission requirements, and regional endpoint URLs, refer to the official AWS documentation at docs.aws.amazon.com/agent-toolkit/latest/userguide/mcp-server.html. Specific IAM policy configurations and client setup steps will vary depending on your agent framework.

Open Source: Inspect Before You Trust

One significant detail in the AWS announcement: both the underlying components are available as open-source repositories on GitHub:

  • awslabs/mcp — the MCP server implementation
  • aws/agent-toolkit-for-aws — the full Agent Toolkit

This matters for enterprise teams. You’re not taking AWS’s word for what the server does — you can read the code, audit the tool implementations, and understand exactly what actions the server can trigger on your behalf. For AI security teams evaluating this, the open-source approach is exactly the right call.

Why This Is a Big Deal

The AWS MCP Server solves a specific, painful problem that every team building cloud-integrated AI agents has wrestled with.

The naive approach — giving an agent an AWS access key — is a security nightmare. The careful approach — building a custom middleware layer that exposes only specific safe actions — requires significant engineering investment that most teams duplicate independently.

A managed, auditable, IAM-authenticated MCP server from AWS itself changes the calculus. It shifts “how do we safely give agents AWS access” from a custom engineering problem to a configuration problem.

For coding assistants like Cursor, VS Code with Copilot, or any tool with MCP support, the AWS MCP Server means you can ask your coding agent to check a CloudWatch alarm, list S3 buckets, or query CloudTrail logs — with proper authentication and a clear audit trail — without any custom backend work.

Getting Started

  1. Review the official AWS docs: AWS MCP Server User Guide
  2. Explore the Agent Toolkit product page: aws.amazon.com/products/developer-tools/agent-toolkit-for-aws/
  3. Review the open-source implementation: github.com/awslabs/mcp
  4. Configure IAM credentials following AWS least-privilege best practices for your specific use case

The AWS MCP Server is generally available now. No waitlist, no preview sign-up — just configuration.
