Power Strip Security

Overview

Power Strip Security is a Model Context Protocol server that shields agents from prompt injection attacks. It reads pages, scans content, and audits MCP servers and skills to protect your AI workflows from malicious inputs. By speaking MCP, it integrates directly into your AI assistant as callable tools rather than requiring manual copy-paste between applications.

You can deploy Power Strip Security in two ways: use the hosted endpoint at https://api.powerstripsecurity.workers.dev/mcp with zero local setup, or install it locally via npx -y power-strip-security-mcp. Either method requires the PSS_PRIVATE_KEY environment variable for authentication. The latest release is v0.2.0.

Power Strip Security belongs in the AI & Agents category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to earn the Verified badge and keep your details up to date.
