+### mgrep list
+
+`mgrep list` shows all running `mgrep watch` processes with their working directories.
+
+**Example:**
+```bash
+mgrep list
+# /home/user/project-a
+# /home/user/project-b
+```
+
+Output is one directory per line.
+
 ## Mixedbread under the hood
 
 - Every file is pushed into a Mixedbread Store using the same SDK your apps get.
