#### Tool Safety Levels

**✅ Safe for Auto-Approval (`alwaysAllow`)**
- `test-connection` - Connection validation (read-only)
- `execute-soql` - SOQL queries (read-only)
- `describe-sobject` - Metadata inspection (read-only)
- `get-record` - Single record retrieval (read-only)
- `get-apex-logs` - Debug log access (read-only)
- `list-metadata-types` - Metadata type discovery (read-only)

**⚠️ Requires Manual Approval**
- `create-record`, `update-record`, `delete-record`, `upsert-record` - Data modification
- `deploy-metadata` - Metadata deployment
- `execute-apex`, `run-apex-tests` - Code execution
- `execute-sosl` - Search operations (can be resource-intensive)
- `retrieve-metadata` - Metadata retrieval (can be large)


## Authentication

### Username/Password Authentication
1. Obtain your security token from Salesforce Setup → Personal Information → Reset Security Token (only required if your IP is not trusted)
2. Set environment variables as shown in the configuration section
3. Use `https://login.salesforce.com` for production or `https://test.salesforce.com` for sandboxes

> **💡 Security Token**: Only add the security token if Salesforce requires it for your connection. If not leave `SF_SECURITY_TOKEN` empty.

### OAuth2 Authentication
1. Create a Connected App in Salesforce Setup
2. Configure OAuth settings and obtain client credentials
3. Generate a refresh token using the OAuth2 flow
4. Set environment variables as shown in the configuration section

## 🏗️ Architecture

### Core Components
- **Authentication Manager** - Dual OAuth2/Username-Password support
- **Connection Manager** - Singleton pattern with health monitoring
- **Tool Classes** - Organized by functionality (Query, Apex, Data, Metadata)
- **Error Handler** - Comprehensive error formatting with context
- **Cache Manager** - TTL-based caching for performance optimization

### Performance Features
- **Auto-Bulk Switching** - Automatically uses Bulk API for large operations
- **Intelligent Caching** - SObject metadata cached for 1 hour
- **Connection Reuse** - Single connection across all operations
- **Polling Optimization** - Efficient monitoring of long-running operations
