Duolingo open-sources AI Slack agent that connects to 200+ engineering tools

Properly proved. Has structure, has flavour, has a point.
Summary
Duolingo developed an internal AI Slack app that connects to over 200 tools (GitHub, Jenkins, Sentry, Grafana, etc.) to help engineers triage, debug, and ship code directly from Slack. What started as local experiments by a few engineers grew into a tool used weekly by 30% of the company. The project, which leverages Anthropic's Model Context Protocol (MCP), has now been open-sourced on GitHub. The AI agent can perform complex multi-step tasks like investigating production incidents, deploying code, and querying databases—all through natural language commands in Slack.
