+DEPRECATION NOTICE
+The CLI entry-point used to start the Cognee MCP service has been renamed from
+"cognee" to "cognee-mcp". Calling the old entry-point will stop working in a
+future release.
+
+WHAT YOU NEED TO DO:
+Locate every place where you launch the MCP process and replace the final
+argument cognee → cognee-mcp.
+
+For the example mcpServers block from Cursor shown below the change is:

+      ]
+    }
+  }

+
+Continuing to use the old "cognee" entry-point will result in failures once it
+is removed, so please update your configuration and any shell scripts as soon
+as possible.
