## Dependencies
- [zig-jni](https://github.com/SuperIceCN/zig-jni) (v0.0.9) - JNI bindings for Zig
## Building
1. Clone the repository:
```bash
git clone https://github.com/yourusername/ghidra-mcp-zig.git
cd ghidra-mcp-zig
```
2. Create a `.env` file with the following variables:
```
GHIDRA_PATH=/path/to/ghidra_11.3.1_PUBLIC/Ghidra/Features/Base/lib/Base.jar
JAVA_HOME=/path/to/your/jdk
```
3. Build the project:
```bash
# Build everything
make all
# Or build specific components
make build-server # Build the MCP server
make build-plugin # Build the Ghidra plugin
```
4. Run the server:
```bash
make run-server
```
### Build Targets
| Target | Description | Example Usage |
|--------|-------------|---------------|
| `all` | Build all components | `make all` |
| `build-server` | Build MCP server | `make build-server` |
| `build-plugin` | Build Ghidra plugin | `make build-plugin` |
| `clean` | Clean all artifacts | `make clean` |
| `clean-server` | Clean server artifacts | `make clean-server` |
| `clean-plugin` | Clean plugin artifacts | `make clean-plugin` |
### Run Targets
| Target | Description | Example Usage |
|--------|-------------|---------------|
| `run-server` | Start MCP server | `make run-server` |
| `run-plugin` | Start Ghidra plugin | `make run-plugin` |
### Test Targets
| Target | Description | Example Usage |
|--------|-------------|---------------|
| `test` | Run all tests | `make test` |
| `test-server` | Run server tests | `make test-server` |
| `test-plugin` | Run plugin tests | `make test-plugin` |
For a complete list of available targets, run:
```bash
make help
```
## Installation
1. Build the plugin:
```bash
make build-plugin
```
2. Copy the built plugin to your Ghidra plugins directory:
```bash
cp zig-out/lib/libghidra-mcp-zig.dylib /path/to/ghidra/Extensions/Ghidra/ghidra-mcp-zig/
```
3. Restart Ghidra
## Usage
1. Start Ghidra and open a program for analysis
2. The MCP plugin will be available in the Ghidra plugin manager
3. Use the plugin's features through the Ghidra interface
### Available MCP Commands
| Command | Description | Parameters |
|---------|-------------|------------|
| `decompile` | Decompile a function | `address: u64` |
| `rename_function` | Rename a function | `address: u64, new_name: string` |
| `rename_data` | Rename a data object | `address: u64, new_name: string` |
| `list_functions` | List all functions | None |
| `list_data` | List all data objects | None |
| `list_imports` | List all imports | None |
| `list_exports` | List all exports | None |
### Error Handling
The implementation includes comprehensive error handling with specific error types:
| Error Type | Description |
|------------|-------------|
| `ConnectionError` | Connection-related errors |
| `MessageError` | Message handling errors |
| `ResponseError` | Response parsing errors |
| `InvalidAddress` | Invalid memory address |
| `InvalidFunction` | Invalid function reference |
| `InvalidData` | Invalid data reference |
| `DecompilationFailed` | Function decompilation failed |
| `RenameFailed` | Rename operation failed |
| `OutOfMemory` | Memory allocation failed |
| `InvalidProgram` | Invalid program state |
| `JNIError` | JNI bridge errors |
## Development
### Adding New Features
1. Update the JNI interface in `src/plugin/jni/bridge.zig`
2. Implement the corresponding functionality in `src/plugin/analysis.zig`
3. Update the server implementation in `src/server/main.zig` if needed
4. Rebuild and test
### Debugging
- Use `make clean` to remove build artifacts
- Check the Ghidra log for plugin-related messages
- The server logs will be available in the console when running with `make run-server`
### JNI Bridge Implementation
The JNI bridge provides a type-safe interface between Zig and Java:
- Memory management with proper allocation/deallocation
- JNI reference management with `DeleteLocalRef`
- Error handling with null checks
- Type conversion between Zig and Java types
- Array creation and element setting
- Object creation and field setting
#### Key Features
1. **Memory Safety**
- Automatic cleanup of JNI references
- Proper string handling with UTF-8 conversion
- Safe memory allocation and deallocation
2. **Type Safety**
- Strong typing for all JNI operations
- Compile-time type checking
- Safe type conversions
3. **Error Handling**
- Comprehensive error types
- Null checks for all JNI operations
- Proper cleanup on error
4. **Object Management**
- Safe object creation and destruction
- Field access with type checking
- Array handling with bounds checking
