+## 📊 Analytics & Telemetry
+
+### MCPcat Analytics
+[MCPcat](https://mcpcat.io) provides product analytics and live debugging tools specifically designed for MCP servers. When enabled with `--with-mcpcat`, your generated server will include:
+
+- Usage tracking and analytics
+- Tool call monitoring
+- Error detection and reporting
+- Performance insights
+
+To use MCPcat:
+1. Sign up for free at [mcpcat.io](https://mcpcat.io)
+2. Get your project ID
+3. Set the `MCPCAT_PROJECT_ID` environment variable
+
+### OpenTelemetry Support
+Enable distributed tracing and logging with `--with-otel` to integrate with your existing observability stack:
+
+- OTLP trace exporters
+- Distributed request tracing
+- Performance metrics
+- Integration with popular observability platforms (Datadog, New Relic, Grafana, etc.)
+
+Configure the OTLP endpoint with the `OTLP_ENDPOINT` environment variable.
+
+### Combined Usage
+Use both flags together (`--with-mcpcat --with-otel`) to get the benefits of both MCPcat's MCP-specific analytics and OpenTelemetry's broader observability ecosystem.
+
+#### Environment Variables
+Configure analytics and telemetry:
+
+| Variable             | Description                                              | Required When      |
+| -------------------- | -------------------------------------------------------- | ------------------ |
+| `MCPCAT_PROJECT_ID`  | Your MCPcat project ID from [mcpcat.io](https://mcpcat.io) | `--with-mcpcat`    |
+| `OTLP_ENDPOINT`      | OpenTelemetry collector endpoint URL                    | `--with-otel`      |
+

 ## 🔎 Filtering Endpoints with OpenAPI Extensions
 
 You can control which operations are exposed as MCP tools using a vendor extension flag `x-mcp`. This extension is supported at the root, path, and operation levels. By default, endpoints are included unless explicitly excluded.
