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
