Send OpenTelemetry traces to Agent Observability, no SDK required
You can now send OpenTelemetry traces straight to Agent Observability, without the SDK. If your agents already emit OpenTelemetry generative AI spans, from your framework, an instrumentation library, or spans you write yourself, keep your existing route through Grafana Alloy or an OpenTelemetry Collector and opt in your AI spans with a single attribute.

We are pleased to announce the preview of Cortex Tools, a part of Cortex AI Gateway that connects the AI clients your organization uses to the business tools your work already lives in, using the Model Context Protocol (MCP). Supported clients include CoCo Desktop, CoCo CLI, Claude, and Cursor.
