Agent Loop Detector
Built to catch when AI agents get stuck in repetitive loops during task execution. This runs as a Cloudflare Worker and exposes both REST and MCP interfaces over streamable HTTP, so you can integrate loop detection into your agent workflows without spinning up your own infrastructure. Reach for this when you're building autonomous agents that might spiral into the same actions repeatedly and you want an external service to flag the pattern. The MCP interface means Claude can directly call it during conversations to check if it's repeating itself across tool calls or reasoning steps.

Install
From registry metadata$ npx add-mcp https://api.lazy-mac.com/agent-loop-detector/mcp --name agent-loop-detectorRun in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.
Review the command, arguments and environment values before installing. MCP servers run with your local permissions.
Other ways
Claude Code
$ claude mcp add --transport http agent-loop-detector https://api.lazy-mac.com/agent-loop-detector/mcpRun in your terminal. Add --scope user to make it available in every project.
