+### Disabling Specific Tools
+
+You can disable specific tools using the `-d` or `--disable-tools` flag:
+
+```json
+{
+  "mcpServers": {
+    "filesystem": {
+      "command": "rust-mcp-filesystem",
+      "args": [
+        "-d", "write_file,edit_file,move_file",
+        "~/Documents"
+      ]
+    }
+  }
+}
+```
+
+This example disables `write_file`, `edit_file` and `move_file`. See the [CLI Options](../guide/cli-command-options.md) documentation for more details.
+
 ## Running via Docker
 
 **Note:** In the example below, all allowed directories are mounted to `/projects`,  and `/projects` is passed as the allowed directory argument to the server CLI. You can modify this as needed to fit your requirements.
 
-`ALLOW_WRITE` and `ENABLE_ROOTS` environments could be used to enable write and MCP Roots support.

+## Disabling Tools
+
+You can disable specific tools to limit the functionality of the server. This is useful for:
+
+- Security hardening by disabling write operations
+- Reducing the number of available tools to save tokens
+- Customizing available functionality for specific use cases
+
+### Examples
+
+```sh
+# Disable write-related tools
+rust-mcp-filesystem -d write_file,edit_file,move_file /path/to/dir
+
+# Disable multiple tools
+rust-mcp-filesystem -d read_text_file,search_files /path/to/dir
+
+# Using environment variable
+DISABLE_TOOLS=write_file,edit_file rust-mcp-filesystem /path/to/dir
+
+# Disable all write tools at once
+rust-mcp-filesystem -d write_file,edit_file,move_file,create_directory,delete_file,zip_files,unzip_file /path/to/dir
+```
+
+### Available Tool Names
+
+For a complete list of available tools and their names, see the [Capabilities](https://rust-mcp-stack.github.io/rust-mcp-filesystem/#/capabilities) page. Tool names are case-insensitive (e.g., `read_text_file` and `Read_Text_File` are equivalent).
