AWS KB Retrieval MCP Server
An MCP server for querying AWS Knowledge Bases via Bedrock Agent Runtime.
Data last scanned yesterday · Reviewed 2 months ago
Overview
The aws-kb-retrieval-server enables retrieval-augmented generation (RAG) workflows by connecting your MCP-compatible environment to AWS Knowledge Bases. It provides a single tool, retrieve_from_aws_kb, which allows you to fetch context using a specific knowledge base ID and search query. You can also customize the number of results returned to refine the information retrieved from your AWS data stores. Configuration requires providing valid AWS credentials, including access keys and region details, which are passed directly to the server environment. It supports integration with development tools like Claude Desktop and VS Code via Docker or NPX, facilitating direct access to your AWS data for AI-assisted analysis.
Our verdict
This server carries a high risk level with a security score of 0/100 and should be used with extreme caution. The project is officially archived, meaning it receives no further security patches or maintenance. Furthermore, it lacks any authentication mechanism, which exposes the service to unauthorized access if misconfigured. Given these critical limitations, it is not recommended for production environments or systems handling sensitive data.
Setup
{
"mcpServers": {
"aws-kb-retrieval-server": {
"args": [
"-y",
"@modelcontextprotocol/server-aws-kb-retrieval"
],
"command": "npx"
}
}
}Paste into ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Some servers require API keys or tokens as environment variables — check the project's README and add an "env" object if needed.
- No read-only mode — running this grants full read/write access.
- No built-in authentication — anyone with access to this config can invoke every tool it exposes.
