• Automatic Detection: Claude automatically suggests this tool when authentication is needed
• No Manual Setup: Eliminates the need to run npm run setup manually
• Smart Authentication: Only authenticates when necessary, checks existing tokens first
• Seamless Integration: Works transparently in the background

This tool is automatically suggested when:

• You try to use Salesforce tools without authentication
• Your tokens have expired
• Authentication errors occur
• First-time setup is needed

🧠 Smart Learning System

Why is Learning Important?

Every Salesforce installation is unique with:

• Custom Objects like "TimeTracking__c", "Project__c", "CustomerCare__c"
• Custom Fields on standard objects
• Specific Workflows and validation rules
• Individual Data Structures

The AI's normal training model only knows standard Salesforce objects. Without knowledge of your specific installation, the AI cannot provide intelligent assistance.

How Does Learning Work?

1. One-time Analysis: salesforce_learn analyzes your complete installation
2. Local Documentation: All objects, fields and relationships are stored locally
3. Intelligent Support: Claude can then make precise suggestions and answer complex questions

Example Workflow:

You: "Are there any time tracking entries for July 2025?"

Without Learning:
❌ Claude: "I don't know any object called 'TimeTracking'"

With Learning:
✅ Claude: "I'm checking the 'TimeTracking__c' object for entries from July 2025..."
   Automatically executes the correct SOQL query

When Should You Use Learning?

• During initial setup - Once after installation
• After major changes - When new Custom Objects are added
• When having problems - When Claude doesn't find objects or fields

What is Learned?

• All SObjects (Standard and Custom)
• All Fields with data types and permissions
• Relationships between objects
• Picklist Values and validation rules
• Required Fields for better validation

💡 Learning runs only once and then makes all further interactions much more intelligent!

💡 Usage Examples

🚀 First Steps After Installation

1. Authentication: Claude automatically detects when authentication is needed
2. Start Learning:

   You: "Learn my Salesforce installation"
   Claude: Automatically uses the salesforce_learn tool
   

3. Explore Installation:

   You: "Show me an overview of my Salesforce installation"
   Claude: Uses salesforce_installation_info for a summary
   

🔍 Intelligent Queries with Learned Installation

You: "Show me all projects from this year"
Claude: Automatically recognizes your "Project__c" Custom Object and creates:
SELECT Id, Name, StartDate__c, Status__c FROM Project__c WHERE CALENDAR_YEAR(CreatedDate) = 2025

You: "Are there any time tracking entries for July 2025?"
Claude: Finds your "TimeTracking__c" object and queries:
SELECT Id, Name, Month__c, Hours__c FROM TimeTracking__c WHERE Month__c = 'July 2025'

Query Examples

-- Get all accounts in the technology industry
SELECT Id, Name, Industry, Website FROM Account WHERE Industry = 'Technology'

-- Find contacts created this week
SELECT Id, Name, Email, CreatedDate FROM Contact WHERE CreatedDate = THIS_WEEK

-- Get opportunities closing this quarter
SELECT Id, Name, Amount, CloseDate FROM Opportunity WHERE CloseDate = THIS_QUARTER

Working with Custom Objects

The server automatically discovers custom objects:

// Describe a custom object
{
  "sobject": "CustomProject__c"
}

// Query custom object
{
  "query": "SELECT Id, Name, CustomField__c FROM CustomProject__c LIMIT 10"
}

// Create custom object record
{
  "sobject": "CustomProject__c",
  "data": {
    "Name": "New Project",
    "CustomField__c": "Custom Value"
  }
}

🐛 Troubleshooting

Authentication Issues

🎯 Automatic Authentication: Claude automatically detects authentication issues and suggests the salesforce_auth tool. No manual troubleshooting needed!

Common Scenarios:

1. First-time use: Claude will automatically suggest authentication when you first try to use Salesforce tools
2. Token expiration: When tokens expire, Claude detects this and prompts for re-authentication
3. Invalid credentials: Clear error messages guide you to fix configuration issues
4. Session expired: Automatic detection with friendly prompts to re-authenticate

Token Security

🔒 Secure Token Storage: Authentication tokens are stored securely in the local file system with strict permissions.

Security Features:

• File Permissions: Token files are created with 0600 permissions (readable/writable only by owner)
• Location: Tokens stored in cache/salesforce-tokens.json (excluded from git)
• Automatic Security: Permission verification and automatic fixing if needed
• No Network Exposure: Tokens never leave your local machine
• File-based Security: Secure token storage with strict file permissions for credential protection

Security Verification:

# Check token file security
ls -la cache/salesforce-tokens.json
# Should show: -rw------- (600 permissions)

# Run security test
node test-token-security.js

What this means:

• Other users on your system cannot read your Salesforce tokens
• Only your user account has access to the authentication data
• Prevents unauthorized access to your Salesforce organization
• Complies with security best practices for credential storage

Quick Fix in Claude Desktop

If you get authentication errors, simply tell Claude:

Authenticate with Salesforce

Or Claude will automatically suggest: Use the salesforce_auth tool to authenticate with Salesforce

✨ No more manual terminal setup! Everything happens seamlessly through Claude Desktop.

Connection Issues

1. "Cannot connect to Salesforce": Verify your Instance URL
2. "Insufficient permissions": Check user permissions in Salesforce
3. "CORS errors": Ensure Connected App callback URL is correct

Common SOQL Errors

1. Field not found: Use API names, not field labels
2. Object not found: Check spelling and API name of objects
