+## Render MCP in Codex
+
+This plugin declares the hosted Render MCP server in `.mcp.json` with the pre-registered Codex OAuth client id. After installing or updating the plugin, Codex can connect to `https://mcp.render.com/mcp` and prompt for Render OAuth when MCP tools are first used.
+
+No `RENDER_API_KEY` or `codex mcp add` command is needed for the plugin-provided MCP connection. Manual API-key setup is still useful for other AI tools or when using the Render CLI fallback.

 ## Set up the Render CLI
 
 Many Render workflows depend on the Render CLI.
