      "command": "npx",
      "args": [
        "-y",

@shieldly/mcp

AI-Powered Security Analysis for AWS — official MCP server.

Gives any MCP-compatible AI assistant (Claude Code, Claude Desktop, Cursor, etc.) two tools to analyze AWS IAM policies and CloudFormation templates for security risks — privilege escalation paths, wildcards, and other over-permissive access. Powered by Shieldly.

Setup

Add to your MCP client config (e.g. Claude Desktop's claude_desktop_config.json, or Claude Code's .mcp.json):

"mcpServers": { "shieldly": { "command": "npx", "args": ["-y", "@shieldly/mcp"] } } }

Try it free — no account needed

Both tools run in demo mode without an API key (rate-limited, no signup). For higher limits, set SHIELDLY_API_KEY:

"mcpServers": { "shieldly": { "command": "npx", "args": ["-y", "@shieldly/mcp"], "env": { "SHIELDLY_API_KEY": "sk_live_..." } } } }

Get an API key (Builder plan or above): https://www.shieldly.io/app/api
