+## CLI Tool
+
+GhydraMCP includes `ghydra`, a command-line tool for interacting with Ghidra directly from the terminal. It works standalone — no MCP client needed.
+
+```bash
+# Install
+pip install -e .
+
+# List running Ghidra instances
+ghydra instances list
+
+# Decompile a function
+ghydra functions decompile --name main
+
+# List strings matching a pattern
+ghydra data list-strings --filter "password"
+
+# Read memory as hex dump
+ghydra memory read --address 0x401000 --length 64
+
+# JSON output for scripting and piping
+ghydra --json functions list | jq '.result[].name'
+```
+
+All commands support `--host`, `--port`, `--json`, and `--no-color` flags. See [GHYDRA_CLI.md](GHYDRA_CLI.md) for the full reference.
