# binary_ninja_cline_mcp
An MCP server for Cline that works with Binary Ninja (Personal License)
This repository contains an MCP server that allows Cline to analyze binaries using Binary Ninja.
Note: Not all files will be used, there is also prototype of using headless Binary Ninja but my
license is Personal so I can't test it.
## Setup
1. Install the latest of Binary Ninja MCP Plugin https://github.com/fosdickio/binary_ninja_mcp
2. Open your binary and start the MCP server from within Binary Ninja.
3. Open a terminal and run python binary_ninja_mcp_http_server.py --port 8088
4. Open another terminal and run `npm start`
5. Open Cline and add the following tool:{
Example:
```
{
"mcpServers": {
"BN MCP": {
"command": "node",
"args": ["/home/matteius/binary_ninja_cline/bn_cline_mcp/binaryninja-mcp-bridge.js"],
"env": {
"BN_HTTP_SERVER": "http://localhost:8088"
},
"autoApprove": [],
"disabled": false,
"timeout": 30
}
}
}
```

# Extended Binary Ninja MCP Client
This project extends the Binary Ninja MCP client to provide more comprehensive binary analysis capabilities through the Model Context Protocol (MCP).
## Features
The extended client adds the following capabilities:
### Basic Binary Analysis
- Get binary metadata
- List functions, sections, imports, exports
- Get detailed function information
- Disassemble and decompile functions
- Search for functions by name
- List C++ namespaces
- List and analyze data variables
### Advanced Analysis
- Generate comprehensive analysis reports
- Find potential vulnerabilities in binaries
- Compare two binaries to identify differences
- Rename functions and data variables
## Setup
1. Install dependencies:
```bash
cd bn_cline_mcp
npm install
npm install --save-dev @types/node
```
2. Make sure Binary Ninja is running with the MCP plugin installed.
## Usage
### TypeScript Client
The TypeScript client provides a simple API for interacting with Binary Ninja:
```typescript
import { BinaryNinjaClient } from './client';
async function main() {
const client = new BinaryNinjaClient();
try {
// Start the server
await client.start('/path/to/binaryninja_server.py');
// Load a binary file
const binaryPath = '/path/to/binary';
// Get binary information
const info = await client.getBinaryInfo(binaryPath);
console.log(info);
// List functions
const functions = await client.listFunctions(binaryPath);
console.log(functions);
// Decompile a function
const decompiled = await client.decompileFunction(binaryPath, functions[0]);
console.log(decompiled);
// Generate a comprehensive analysis report
const report = await client.analyzeFile(binaryPath, 'report.json');
console.log(`Found ${report.function_count} functions`);
// Find potential vulnerabilities
const vulnerabilities = await client.findVulnerabilities(binaryPath);
console.log(`Found ${vulnerabilities.length} potential vulnerabilities`);
} catch (err) {
console.error('Error:', err);
} finally {
// Stop the server
client.stop();
}
}
main().catch(console.error);
```
### Example Scripts
The `examples` directory contains example scripts that demonstrate how to use the extended client:
- `binary_analysis.ts`: Demonstrates comprehensive binary analysis capabilities
To run an example:
```bash
cd bn_cline_mcp
npx ts-node examples/binary_analysis.ts /path/to/binary [output_dir]
```
## API Reference
### Basic Operations
- `getBinaryInfo(path: string)`: Get information about a binary file
- `listFunctions(path: string)`: List all functions in a binary file
- `getFunction(path: string, functionName: string)`: Get detailed information about a specific function
- `disassembleFunction(path: string, functionName: string)`: Disassemble a function
- `decompileFunction(path: string, functionName: string)`: Decompile a function to C code
- `listSections(path: string)`: List all sections/segments in a binary file
- `listImports(path: string)`: List all imported functions
- `listExports(path: string)`: List all exported symbols
- `listNamespaces(path: string)`: List all C++ namespaces
- `listData(path: string)`: List all defined data variables
- `searchFunctions(path: string, query: string)`: Search for functions by name
- `renameFunction(path: string, oldName: string, newName: string)`: Rename a function
- `renameData(path: string, address: string, newName: string)`: Rename a data variable
### Advanced Analysis
- `analyzeFile(path: string, outputPath?: string)`: Generate a comprehensive analysis report
- `findVulnerabilities(path: string)`: Find potential vulnerabilities in a binary file
- `compareBinaries(path1: string, path2: string)`: Compare two binary files and identify differences
## Extending the Client
You can extend the client by adding new methods to the `BinaryNinjaClient` class in `client.ts`. If you need to add new server-side functionality, you'll need to:
1. Add a new tool definition to the `MCP_TOOLS` array in `binaryninja_mcp_http_server.py`
2. Implement the handler for the new tool in the `_handle_mcp_request` method
3. Add a corresponding method to the `BinaryNinjaClient` class in `client.ts`
## Troubleshooting
- Make sure Binary Ninja is running and the MCP plugin is installed
- Check that the server path in `client.start()` is correct
- If you get TypeScript errors, make sure you've installed the required dependencies with `npm install --save-dev @types/node`
## Handling Timeouts
The client includes built-in retry logic to handle occasional timeouts that may occur when communicating with the Binary Ninja MCP server. By default, each request will:
- Timeout after 30 seconds if no response is received
- Automatically retry up to 3 times with a 1-second delay between attempts
- Log detailed error information for debugging
You can customize the retry behavior when making requests:
```typescript
// Custom retry options
const result = await client.sendRequest('some_method', { param: 'value' }, {
maxRetries: 5, // Retry up to 5 times
retryDelay: 2000 // Wait 2 seconds between retries
});
```
This makes the client more robust when dealing with large binaries or complex analysis tasks that might occasionally cause timeouts.
