Tripwire

Overview

Tripwire is a Model Context Protocol server that acts as a security gateway for MCP agents, blocking prompt-injection-driven tool calls before they execute. Any MCP-compatible AI assistant can integrate Tripwire to add a protective layer that prevents malicious prompts from triggering unintended tool use.

The server runs locally on your machine via the npm package tripwire-mcp, which communicates over stdio. No authentication or credentials are needed—simply install with npx -y tripwire-mcp and it works immediately. The latest release is v0.3.1, distributed under the MIT license with source code available at bonesdefi/Tripwire on GitHub.

Tripwire is categorized under AI & Agents and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain Tripwire, you can claim this listing to earn the Verified badge and ensure the information stays accurate.
