Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
PrefectCommand (node, npx, python, etc.)uvxArguments-

- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
The server is configured via the .cursor/mcp.json file. The updated configuration is as follows:
{
"mcpServers": {
"prefect": {
"command": "uvx",
"args": [
"prefect-mcp-server"
],
"env": {}
}
}
}
This configuration ensures that the server uses the uvx command with the exact package version installed via uv pip install. This approach provides enhanced reliability and consistency in your development environment.
Set the following environment variables to configure your Prefect environment. You can create a file named .env in the project root with entries such as:
PREFECT_API_URL=http://localhost:4200/api
Additionally, if needed, set other environment variables like PREFECT_API_KEY to authenticate with your Prefect server or Prefect Cloud.
To start the server, you can run the following command:
uv run <script>
Alternatively, if you are using the Cursor IDE with its configuration, the server will be automatically invoked with the command specified in .cursor/mcp.json.
