# MCP OpenTelemetry Server Demo  Demonstration of a Remote MCP server instrumented with OpenTelemetry tracing and sending traces to Datadog. This provides a single connected trace from MCP server through to any backend APIs or databases giving you a complete understanding of your MCP server availability. Features: * Bundles a lightweight OpenTelemetry collector using [rotel](https://github.com/streamfold/pyrotel) * Scripts that deploy to [Render](https://render.com/) * Pushes trace spans to Datadog (using early experimental rotel trace support) * Pulls the latest weather forecast from a configurable backend API ## Deploying to Render 1. Clone repo 2. Setup a new webservice in Render using the repo fork 3. Set the following Render properties: - Build script: `./scripts/render-build.sh` - Run script: `./scripts/render-start.sh` 4. Set the following environment variables: - `DATADOG_API_KEY`: Your Datadog API key - `DATADOG_REGION`: defaults to us1, options: us3, us5, eu, ap1 - `WEATHER_API`: API endpoint of an API returning weather forecast given a zipcode 5. Deploy! You can use the [MCP Inspector](https://github.com/modelcontextprotocol/inspector) to connect to your new MCP Server's endpoint for testing. ## TODO This application **does not** include authentication/authorization support, so make sure to adjust to your particular needs. Cloudflare has [discussed](https://blog.cloudflare.com/remote-model-context-protocol-servers-mcp/) their recent approach for how to use an OAuth flow for MCP. ## Developing This project uses [uv](https://github.com/astral-sh/uv), to get started use `uv sync` to install dependencies.
