Over the past few months, we’ve introduced a series of enhancements to FusionReactor designed to advance observability, simplify troubleshooting, and bring AI-driven capabilities into your workflows. Together, these updates represent a significant step forward in how engineering teams can monitor, investigate, and optimize their systems. Below is a summary of the most impactful new features now available in FusionReactor.
FR Cloud MCP
With FR Cloud MCP, you can now connect AI assistants such as Claude Desktop directly to your FusionReactor Cloud data. This integration allows you to:
- Access real-time insights from within your AI workflows
- Run live queries against observability data
Leverage the open-source Grafana MCP project for streamlined connectivity
This functionality ensures that observability data is available precisely where and when you need it.
