deadends.dev is a Model Context Protocol (MCP) server: Structured failure knowledge for AI agents — dead ends, workarounds, error chains. Because it speaks the Model Context Protocol, AI assistants can use deadends.dev as a set of callable tools instead of you copy-pasting between apps.
You can run deadends.dev two ways: connect to the hosted endpoint at https://deadends.dev/mcp with no local install, or run it on your own machine via the Python package deadends-dev (via uvx). The current release is v0.9.0, published under the MIT license, with source at dbwls99706/deadends.dev on GitHub.
On mcp.site, deadends.dev sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
