AWS Knowledge MCP Server

What is AWS Knowledge MCP Server?

The AWS Knowledge MCP Server is a fully managed remote MCP server from AWS that gives AI agents current AWS documentation, API references, regional availability data and AWS agent skills. It requires no authentication and no AWS account.

AWS publishes it as part of the open-source AWS MCP servers project (awslabs), and it is in general availability. Because AWS changes constantly, a model's training data quickly goes stale; this server lets an assistant search and read the live documentation, check whether a service, API or CloudFormation resource exists in a given Region, and load step-by-step AWS skills before it answers or writes infrastructure code.

How to use AWS Knowledge MCP Server?

The endpoint uses Streamable HTTP and needs no credentials. Usage is subject to rate limits and the AWS Site Terms.

Cursor

In ~/.cursor/mcp.json:

{
  "mcpServers": {
    "aws-knowledge-mcp-server": {
      "url": "https://knowledge-mcp.global.api.aws"
    }
  }
}

VS Code

In .vscode/mcp.json:

{
  "servers": {
    "aws-knowledge-mcp-server": {
      "type": "http",
      "url": "https://knowledge-mcp.global.api.aws"
    }
  }
}

Clients without HTTP support

AWS documents a stdio-to-HTTP proxy using fastmcp:

{
  "mcpServers": {
    "aws-knowledge-mcp-server": {
      "command": "uvx",
      "args": ["fastmcp", "run", "https://knowledge-mcp.global.api.aws"]
    }
  }
}

Key features of AWS Knowledge MCP Server

• Official, fully managed AWS server in general availability.
• No authentication and no AWS account required.
• Search across AWS documentation, API/SDK/CLI references, new and announced features, troubleshooting content, and Amplify and CDK docs.
• Search results contain verbatim chunks of the real page, so answers can cite the source text.
• Full-page reads converted to Markdown when a chunk is not enough.
• Regional availability for products, service APIs and CloudFormation resources.
• AWS agent skills: packaged workflows and reference files an agent can load on demand.

AWS Knowledge MCP Server tools

Documentation. aws___search_documentation searches AWS docs by topic, such as reference_documentation, current_awareness (new or announced features), troubleshooting, amplify_docs and CDK content. Each result's context is real page text. aws___read_documentation fetches a full doc page as Markdown; its description tells the model to use it only when search chunks lack the needed detail, such as complete lists.

Regions. aws___list_regions returns all AWS Regions. aws___get_regional_availability reports whether products, service APIs or CloudFormation resources are available, not available or planned in up to 10 Regions; filter values must exactly match AWS catalog names.

Skills. aws___retrieve_skill returns an AWS skill's SKILL.md or one of its files. The skill name must be copied from a search result rather than guessed.

Use cases of AWS Knowledge MCP Server

• Fact-checking infrastructure code: "Check the current CloudFormation properties for AWS::Lambda::Function before you write this template."
• Region planning: "Is Amazon Bedrock available in eu-central-2 and ap-southeast-4?"
• Staying current: "What did AWS announce for S3 in the last few months?"
• Troubleshooting: "Search AWS docs for this AccessDenied error when assuming a role across accounts."
• Guided workflows: "Find an AWS skill for setting up this service and follow it."

Troubleshooting AWS Knowledge MCP Server

• Requests are throttled. The server is subject to rate limits. Space out calls, and prefer answering from search chunks instead of re-reading full pages.
• Regional availability says the filter values do not exist. Filter names must match AWS's catalog exactly. Call the tool once for a single Region with a resource type and no filters to list valid names.
• Your client only supports stdio. Use the fastmcp proxy configuration shown above.
