## Overview

This project provides a bridge between AI assistants and IDA Pro, a popular disassembler and debugger used for reverse engineering software. It consists of three main components:

1. **IDA Pro Remote Control Plugin** (`ida_remote_server.py`): An IDA Pro plugin that creates an HTTP server to remotely control IDA Pro functions.
2. **IDA Remote Client** (`idaremoteclient.ts`): A TypeScript client for interacting with the IDA Pro Remote Control Server.
3. **MCP Server** (`index.ts`): A Model Context Protocol server that exposes IDA Pro functionality to AI assistants.

## Features

- Execute Python scripts in IDA Pro from AI assistants
- Retrieve information about binaries:
  - Strings
  - Imports
  - Exports
  - Functions
- Advanced binary analysis capabilities:
  - Search for immediate values in instructions
  - Search for text strings in the binary
  - Search for specific byte sequences
  - Get disassembly for address ranges
- Automate IDA Pro operations through a standardized interface
- Secure communication between components

## Prerequisites

- IDA Pro 8.3 or later
- Node.js 18 or later
- TypeScript

### Example usage ida_remote_server.py

```bash
curl -X POST -H "Content-Type: application/json" -d '{"script":"print(\"Script initialization...\")"}' http://127.0.0.1:9045/api/execute
{"success": true, "output": "Script initialization...\n"}
```

### Example usage MCP Server

## Installation

### 1. Install the IDA Pro Remote Control Plugin

1. Copy `ida_remote_server.py` to your IDA Pro plugins directory:
   - Windows: `%PROGRAMFILES%\IDA Pro\plugins`
   - macOS: `/Applications/IDA Pro.app/Contents/MacOS/plugins`
   - Linux: `/opt/idapro/plugins`

2. Start IDA Pro and open a binary file.

3. The plugin will automatically start an HTTP server on `127.0.0.1:9045`.

### 2. Install the MCP Server

1. Clone this repository:
   ```bash
   git clone <repository-url>
   cd ida-server
   ```

2. Install dependencies:
   ```bash
   npm install
   ```

3. Build the project:
   ```bash
   npm run build
   ```

4. Configure the MCP server in your AI assistant's MCP settings file:
   ```json
   {
     "mcpServers": {
       "ida-pro": {
         "command": "node",
         "args": ["path/to/ida-server/dist/index.js"],
         "env": {}
       }
     }
   }
   ```

## Usage

Once installed and configured, the MCP server provides the following tool to AI assistants:

### run_ida_command

Executes an IDA Pro Python script.

**Parameters:**
- `scriptPath` (required): Absolute path to the script file to execute
- `outputPath` (optional): Absolute path to save the script's output to

**Example:**

```python
# Example IDA Pro script (save as /path/to/script.py)
import idautils

# Count functions
function_count = len(list(idautils.Functions()))
print(f"Binary has {function_count} functions")

# Get the first 5 function names
functions = list(idautils.Functions())[:5]
for func_ea in functions:
    print(f"Function: {ida_name.get_ea_name(func_ea)} at {hex(func_ea)}")

# Return data
return_value = function_count
```

The AI assistant can then use this script with:

```
<use_mcp_tool>
<server_name>ida-pro</server_name>
<tool_name>run_ida_command</tool_name>
<arguments>
{
  "scriptPath": "/path/to/script.py"
}
</arguments>
</use_mcp_tool>
```

### search_immediate_value

Searches for immediate values in the binary's instructions.

**Parameters:**
- `value` (required): Value to search for (number or string)
- `radix` (optional): Radix for number conversion (default: 16)
- `startAddress` (optional): Start address for search
- `endAddress` (optional): End address for search

**Example:**

```
<use_mcp_tool>
<server_name>ida-pro</server_name>
<tool_name>search_immediate_value</tool_name>
<arguments>
{
  "value": "42",
  "radix": 10
}
</arguments>
</use_mcp_tool>
```

### search_text

Searches for text strings in the binary.

**Parameters:**
- `text` (required): Text to search for
- `caseSensitive` (optional): Whether the search is case sensitive (default: false)
- `startAddress` (optional): Start address for search
- `endAddress` (optional): End address for search

**Example:**

```
<use_mcp_tool>
<server_name>ida-pro</server_name>
<tool_name>search_text</tool_name>
<arguments>
{
  "text": "password",
  "caseSensitive": false
}
</arguments>
</use_mcp_tool>
```

### search_byte_sequence

Searches for a specific byte sequence in the binary.

**Parameters:**
- `bytes` (required): Byte sequence to search for (e.g., "90 90 90" for three NOPs)
- `startAddress` (optional): Start address for search
- `endAddress` (optional): End address for search

**Example:**

```
<use_mcp_tool>
<server_name>ida-pro</server_name>

```
<use_mcp_tool>
<server_name>ida-pro</server_name>

## IDA Pro Remote Control API

The IDA Pro Remote Control Plugin exposes the following HTTP endpoints:

- `GET /api/info`: Get plugin information
- `GET /api/strings`: Get strings from the binary
- `GET /api/exports`: Get exports from the binary
- `GET /api/imports`: Get imports from the binary
- `GET /api/functions`: Get function list
- `GET /api/search/immediate`: Search for immediate values in instructions
- `GET /api/search/text`: Search for text in the binary
- `GET /api/search/bytes`: Search for byte sequences in the binary
- `GET /api/disassembly`: Get disassembly for an address range
- `POST /api/execute`: Execute Python script (JSON/Form)
- `POST /api/executebypath`: Execute Python script from file path
- `POST /api/executebody`: Execute Python script from raw body

## Security Considerations

By default, the IDA Pro Remote Control Plugin only listens on `127.0.0.1` (localhost) for security reasons. This prevents remote access to your IDA Pro instance.

If you need to allow remote access, you can modify the `DEFAULT_HOST` variable in `ida_remote_server.py`, but be aware of the security implications.
