Agent Failure Archive is a Model Context Protocol (MCP) server: 186 real AI agent post-mortems, 107 of them measurement failures. Free tools, paid via x402. Because it speaks the Model Context Protocol, AI assistants can use Agent Failure Archive as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://desktop-ai2ata5-1.tailfeb765.ts.net/mcp and you're connected, with nothing to install locally. The current release is v0.3.1, with source at HanbeenMoon/agent-failure-archive on GitHub.
On mcp.site, Agent Failure Archive 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.
