| 11 | ## 🤖 What is JADX-AI? |
| 12 | |
| 13 | **JADX-AI** is a modified version of the [original JADX decompiler](https://github.com/skylot/jadx) that integrates directly with [Model Context Protocol (MCP)](https://github.com/anthropic/mcp) to provide **live reverse engineering support with LLMs like Claude**. |
| 14 | |
| 15 | Think: "Decompile → Context-Aware Code Review → AI Recommendations" — all in real time. |

| 21 | It is combination of two tools: |
| 22 | 1. JADX-AI |
| 23 | 2. [JADX MCP SERVER](https://github.com/zinja-coder/jadx-mcp-server) |
| 24 | |
| 25 | ## 🤖 What is JADX-MCP-SERVER? |
| 26 | |
| 27 | **JADX MCP Server** is a standalone Python server that interacts with a modified version of `jadx-gui` (see: [jadx-ai](https://github.com/zinja-coder/jadx-ai)) via MCP (Model Context Protocol). It lets LLMs communicate with the decompiled Android app context live. |
| 28 | |
| 29 | ## Current MCP Tools |
| 30 | |
| 31 | The following MCP tools are available: |
| 32 | |
| 33 | - `fetch_current_class()` — Get the class name and full source of selected class |
| 34 | - `get_selected_text()` — Get currently selected text |
| 35 | - `get_all_classes()` — List all classes in the project |
| 36 | - `get_class_source(class_name)` — Get full source of a given class |
| 37 | - `get_method_by_name(class_name, method_name)` — Fetch a method’s source |
| 38 | - `search_method_by_name(method_name)` — Search method across classes |
| 39 | - `get_methods_of_class(class_name)` — List methods in a class |
| 40 | - `get_fields_of_class(class_name)` — List fields in a class |
| 41 | - `get_method_code(class_name, method_name)` — Alias for `get_method_by_name` //to be removed |
| 42 | - `get_smali_of_class(class_name)` — Fetch smali of class |
