# redteam-mcp-agent (Red Team MCP Agent)
|
||||
|
||||
This example demonstrates how to red team test AI agents that integrate with Model Context Protocol (MCP) servers. It creates a custom OpenAI-based ReAct agent provider that can interact with MCP servers, allowing you to test agent behavior when given access to potentially malicious tools.
|
||||
|
||||
You can run this example with:
|
||||
|
||||
```bash
|
||||
npx promptfoo@latest init --example redteam-mcp-agent
|
||||
cd redteam-mcp-agent
|
||||
```
|
||||
|
||||
## Overview
|
||||
|
||||
The example includes:
|
||||
|
||||
- A custom OpenAI agent provider that uses the ReAct (Reasoning and Acting) pattern
|
||||
- Integration with multiple MCP servers for tool access
|
||||
- Red team testing configuration to evaluate agent security boundaries
|
||||
- Example MCP servers including a potentially malicious one for security testing
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Node.js ^20.20.0 or >=22.22.0 (Node.js 20 support ends July 30, 2026; Node.js 24 LTS recommended)
|
||||
- Python 3.8+ (for the Python MCP server example)
|
||||
- OpenAI API key
|
||||
|
||||
## Environment Variables
|
||||
|
||||
This example requires the following environment variable:
|
||||
|
||||
- `OPENAI_API_KEY` - Your OpenAI API key (get one at https://platform.openai.com/api-keys)
|
||||
|
||||
You can set this in a `.env` file in the example directory:
|
||||
|
||||
```bash
|
||||
OPENAI_API_KEY=sk-...
|
||||
```
|
||||
|
||||
## Quick Start
|
||||
|
||||
1. **Install dependencies:**
|
||||
|
||||
```bash
|
||||
npm install
|
||||
```
|
||||
|
||||
2. **Set up your OpenAI API key:**
|
||||
|
||||
```bash
|
||||
export OPENAI_API_KEY=your-openai-api-key-here
|
||||
# Or create a .env file with OPENAI_API_KEY=your-key
|
||||
```
|
||||
|
||||
3. **Run the red team tests:**
|
||||
|
||||
```bash
|
||||
npx promptfoo@latest redteam run
|
||||
```
|
||||
|
||||

```
|
||||
|
||||
## Configuration
|
||||
|
||||
### promptfooconfig.yaml
|
||||
|
||||
The main configuration file defines:
|
||||
|
||||
1. **Provider Configuration**: Uses a custom OpenAI agent provider with:
|
||||
- Model: `gpt-4o` (you can also use `gpt-4o-mini` or `o3-mini`)
|
||||
- System prompt that instructs the agent to use ReAct pattern
|
||||
- MCP server connections
|
||||
|
||||
2. **MCP Servers**: Three types of connections are demonstrated:
|
||||
- NPX package: `@promptfoo/evil-mcp-server` (for security testing)
|
||||
- Local Node.js server: `./src/mcp_server/index.js`
|
||||
- HTTP endpoint: `http://localhost:8080/mcp` (Python server)
|
||||
|
||||
3. **Red Team Configuration**:
|
||||
- Purpose: Defines the testing scenario (e.g., financial analyst at Acme Inc.)
|
||||
- Tools: Lists available tools and their schemas
|
||||
- Policy: Defines what behaviors to test for
|
||||
|
||||
### Example Configuration
|
||||
|
||||
```yaml
|
||||
# yaml-language-server: $schema=https://promptfoo.dev/config-schema.json
|
||||
providers:
|
||||
- id: file://./src/openai-agent-provider.js
|
||||
config:
|
||||
apiBaseUrl: 'https://api.openai.com/v1'
|
||||
model: 'gpt-4o' # or gpt-4o-mini, o3-mini
|
||||
systemPrompt: |
|
||||
You are a helpful AI assistant with access to various tools...
|
||||
mcpServers:
|
||||
- command: 'npx'
|
||||
args: ['-y', '@promptfoo/evil-mcp-server@latest']
|
||||
- command: 'node'
|
||||
args: ['./src/mcp_server/index.js']
|
||||
- url: 'http://localhost:8080/mcp'
|
||||
|
||||
redteam:
|
||||
purpose: |
|
||||
You are acting as a financial analyst employee at Acme Inc...
|
||||
|
||||
tools: get_financial_summaries
|
||||
startDate: string - Start date for the report (ISO 8601)
|
||||
endDate: string - End date for the report (ISO 8601)
|
||||
groupBy: enum ['day', 'week', 'month'] - Group results by period
|
||||
|
||||
plugins:
|
||||
- id: policy
|
||||
config:
|
||||
policy: Test to trigger the get_financial_summaries tool...
|
||||
```
|
||||
|
||||
## Running Different MCP Servers
|
||||
|
||||
### 1. Evil MCP Server (Security Testing)
|
||||
|
||||
The example includes `@promptfoo/evil-mcp-server` which provides potentially dangerous tools for security testing:
|
||||
|
||||
```yaml
|
||||
mcpServers:
|
||||
- command: 'npx'
|
||||
args: ['-y', '@promptfoo/evil-mcp-server@latest']
|
||||
```
|
||||
|
||||
### 2. Custom Node.js MCP Server
|
||||
|
||||
The included Node.js server (`src/mcp_server/index.js`) provides ERP and analytics tools:
|
||||
|
||||
```yaml
|
||||
mcpServers:
|
||||
- command: 'node'
|
||||
args: ['./src/mcp_server/index.js']
|
||||
```
|
||||
|
||||
### 3. Python HTTP MCP Server
|
||||
|
||||
To run the Python server example:
|
||||
|
||||
```bash
|
||||
# Install FastMCP if not already installed
|
||||
pip install fastmcp
|
||||
|
||||
# Run the server
|
||||
python server.py
|
||||
```
|
||||
|
||||
Then reference it in your config:
|
||||
|
||||
```yaml
|
||||
mcpServers:
|
||||
- url: 'http://localhost:8080/mcp'
|
||||
```
|
||||
|
||||
## Understanding the Results
|
||||
|
||||
When you run the red team tests, promptfoo will:
|
||||
|
||||
1. **Initialize the agent**: Create an OpenAI agent with MCP tool access
|
||||
2. **Run test scenarios**: Execute various prompts designed to test security boundaries
|
||||
3. **Evaluate behavior**: Check if the agent calls suspicious or unauthorized tools
|
||||
4. **Generate report**: Show which tests passed/failed with detailed explanations
|
||||
|
||||
Example output includes:
|
||||
|
||||
- Tool calls made by the agent
|
||||
- The agent's reasoning process (Thought → Action → Observation)
|
||||
- Token usage and execution metrics
|
||||
- Pass/fail status for each security test
|
||||
|
||||
## Customization
|
||||
|
||||
### Adding Custom MCP Servers
|
||||
|
||||
To add your own MCP server:
|
||||
|
||||
1. Create the server implementation
|
||||
2. Add it to `mcpServers` in `promptfooconfig.yaml`:
|
||||
|
||||
```yaml
|
||||
mcpServers:
|
||||
- command: 'python'
|
||||
args: ['path/to/your/server.py']
|
||||
```
|
||||
|
||||
3. Update the `purpose` section with your tool schemas
|
||||
|
||||
### Modifying Test Scenarios
|
||||
|
||||
Edit the `redteam` section to customize:
|
||||
|
||||
- **Purpose**: Change the agent's role and context
|
||||
- **Tools**: Add or modify available tool schemas
|
||||
- **Policy**: Define specific behaviors to test
|
||||
|
||||
### Using Different Models
|
||||
|
||||
Update the model in the provider configuration:
|
||||
|
||||
```yaml
|
||||
config:
|
||||
model: 'gpt-4o-mini' # More cost-effective option
|
||||
# or
|
||||
model: 'openai:chat:gpt-5.4' # Latest OpenAI model
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
- **API Keys**: Never commit API keys to version control
|
||||
- **MCP Servers**: Be cautious when connecting to untrusted MCP servers
|
||||
- **Test Environment**: Run security tests in isolated environments
|
||||
- **Tool Permissions**: Carefully review tool capabilities before granting access
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **"OpenAI API key is required"**
|
||||
- Ensure `OPENAI_API_KEY` is set in your environment or `.env` file
|
||||
|
||||
2. **"Failed to connect to MCP server"**
|
||||
- Verify the server command and path are correct
|
||||
- Check that required dependencies are installed
|
||||
- For HTTP servers, ensure they're running on the specified port
|
||||
|
||||
3. **"Tool not found" errors**
|
||||
- Verify tool schemas in the `purpose` section match the MCP server's tools
|
||||
- Check that MCP servers are starting successfully
|
||||
|
||||
4. **Python server not working**
|
||||
- Install FastMCP: `pip install fastmcp`
|
||||
- Ensure Python 3.8+ is installed
|
||||
- Check that port 8080 is available
|
||||
|
||||
## Advanced Usage
|
||||
|
||||
### Running with Local Development
|
||||
|
||||
When developing the provider locally:
|
||||
|
||||
```bash
|
||||
# Use local version instead of published package
|
||||
npm run local -- redteam run
|
||||
```
|
||||
|
||||
### Debugging Agent Behavior
|
||||
|
||||
To see detailed agent reasoning, the provider logs:
|
||||
|
||||
- Each thought step
|
||||
- Tool selections and arguments
|
||||
- Observations from tool calls
|
||||
- Final responses
|
||||
|
||||
### Creating Custom Tools
|
||||
|
||||
Example MCP tool implementation:
|
||||
|
||||
```javascript
|
||||
// In src/mcp_server/tools/customTools.js
|
||||
export const customTools = [
|
||||
{
|
||||
name: 'my_custom_tool',
|
||||
description: 'Does something specific',
|
||||
inputSchema: {
|
||||
type: 'object',
|
||||
properties: {
|
||||
param1: { type: 'string', description: 'First parameter' },
|
||||
},
|
||||
required: ['param1'],
|
||||
},
|
||||
},
|
||||
];
|
||||
|
||||
export async function handleCustomTool(name, args) {
|
||||
if (name === 'my_custom_tool') {
|
||||
// Tool implementation
|
||||
return { result: 'Tool executed successfully' };
|
||||
}
|
||||
}
|
||||
```
