To configure an MCP server in Junie:

1. Open Junie CLI in your project.
2. Run the /mcp slash command.
3. Follow the Installation Assistant to add a new server (e.g., Astro Docs at https://mcp.docs.astro.build/mcp).

For more details on using MCP with Astro, see the Astro MCP Documentation.

• Right-click the .md file in the Project tool window. • Look for an option that says Mark as Markdown or if it says Mark as Plain Text, it might already be misconfigured. • Alternatively, check the status bar at the bottom right while the file is open. If it says Plain text, click it and select Markdown from the list. • You can also check Settings Editor File Types Files Opened In Associated Applications to make sure it’s not being sent to an external editor.
