Failmodes

Overview

Failmodes is an MCP server that connects you to a comprehensive knowledge base of AI system failure modes. It exposes the Fail Modes taxonomy as tools your AI assistant can invoke, helping you understand, document, and reason about how AI systems can fail.

You can connect to the hosted endpoint at https://www.failmodes.com/api/mcp without any local setup, or install it locally on your machine using npx -y failmodes-mcp. No authentication is required. The server is released under the MIT license, with source code available at elyngved/failmodes-mcp on GitHub.

Failmodes is listed in the AI & Agents category and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, and others. If you maintain this project, you can claim this listing to verify ownership and keep information up to date.
