# Tools Overview

Tools are the building blocks that give your agents the ability to interact with external systems, process data, and perform complex operations. PLai Framework supports 6 different tool types, each designed for specific use cases.

## Tool Configuration

### General Configuration Process

All tools follow a similar configuration pattern:

<Steps>
  <Step title="Select Tool Type">
    Choose the appropriate tool type for your use case
  </Step>

  <Step title="Configure Parameters">
    Fill in required and optional configuration parameters
  </Step>

  <Step title="Test Connection">
    Verify the tool works correctly with test inputs
  </Step>

  <Step title="Add to Agent">
    Assign the tool to one or more agents
  </Step>

  <Step title="Monitor Usage">
    Track tool performance and usage through analytics
  </Step>
</Steps>

### Common Configuration Options

Most tools share these configuration elements:

* **Name**: Human-readable identifier for the tool
* **Description**: Purpose and functionality summary
* **Authentication**: API keys, tokens, or credentials
* **Rate Limits**: Request throttling and usage controls
* **Error Handling**: Retry logic and fallback options
* **Logging**: Activity tracking and debugging info

## Tool Security

### Authentication Methods

<CardGroup cols={3}>
  <Card title="API Keys" icon="key">
    Simple key-based authentication for most APIs
  </Card>

  <Card title="OAuth 2.0" icon="shield">
    Secure token-based authentication for enterprise APIs
  </Card>

  <Card title="Basic Auth" icon="lock">
    Username/password authentication for legacy systems
  </Card>
</CardGroup>

### Security Best Practices

<Warning>
  **Credential Security**: Never expose API keys or credentials in tool descriptions or logs.
</Warning>

<Tip>
  **Environment Variables**: Use environment variables or secure vaults for sensitive credentials.
</Tip>

* **Rotate Credentials**: Regularly update API keys and access tokens
* **Minimal Permissions**: Grant only necessary permissions to tools
* **Monitor Usage**: Track tool usage for unusual activity
* **Audit Logs**: Maintain logs of all tool interactions

## Performance Optimization

### Caching Strategies

Tools can implement various caching mechanisms:

```mermaid theme={null}
graph TD
    A[Agent Request] --> B{Cache Check}
    B -->|Hit| C[Return Cached Result]
    B -->|Miss| D[Execute Tool]
    D --> E[Cache Result]
    E --> F[Return Result]
```

### Rate Limiting

Effective rate limiting strategies:

* **Tool-Level Limits**: Per-tool rate limiting
* **Agent-Level Limits**: Per-agent usage controls
* **Organization-Level Limits**: Global usage caps
* **Dynamic Adjustment**: Automatic limit adjustment based on usage

## Troubleshooting

### Common Issues

<AccordionGroup>
  <Accordion title="Authentication Failures">
    **Symptoms**: 401 or 403 errors, access denied messages

    **Solutions**:

    * Verify API keys and credentials
    * Check permission scopes
    * Confirm rate limits haven't been exceeded
    * Review authentication method configuration
  </Accordion>

  <Accordion title="Connection Timeouts">
    **Symptoms**: Request timeout errors, slow responses

    **Solutions**:

    * Check network connectivity
    * Increase timeout values
    * Implement retry logic
    * Use connection pooling
  </Accordion>

  <Accordion title="Data Format Issues">
    **Symptoms**: Parsing errors, unexpected responses

    **Solutions**:

    * Validate request/response formats
    * Check API documentation
    * Update tool configuration
    * Implement proper error handling
  </Accordion>
</AccordionGroup>

## Tool Development

### Custom Tool Creation

While PLai Framework provides built-in tools, you can extend functionality:

1. **MCP Server Development**: Create custom MCP servers for specialized functionality
2. **API Wrapper Tools**: Build tools that interact with specific APIs
3. **Data Processing Tools**: Develop tools for custom data transformations
4. **Integration Tools**: Create tools for enterprise system integration

### Tool Testing

Comprehensive testing ensures tool reliability:

```typescript theme={null}
// Example tool test
describe('API Request Tool', () => {
  test('should make successful GET request', async () => {
    const tool = new APIRequestTool(config);
    const result = await tool.execute({
      method: 'GET',
      url: 'https://api.example.com/data'
    });
    
    expect(result.status).toBe(200);
    expect(result.data).toBeDefined();
  });
});
```
