Raygun

Connects Claude to Raygun's crash reporting and real user monitoring API, letting you investigate errors, track deployments, and analyze performance through natural language. You get access to error groups with full stack traces, deployment correlation to spot problematic releases, page load metrics, customer session data, and team invitation management. It's hosted remotely at api.raygun.com, so you just add your Personal Access Token and start querying. Useful when you're triaging production issues or want to ask questions like "what errors spiked after the last deployment" without switching contexts to the Raygun dashboard. Supports time series analysis for both errors and performance trends.
