Quick Start with Claude Desktop

Production Usage (Recommended)

The easiest way to use this MCP server is to install it directly from PyPI and configure it with Claude Desktop.

Step 1: Configure Claude Desktop

Add the following configuration to your Claude Desktop settings file:

Configuration File Location:

• macOS/Linux: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Configuration:

{
  "mcpServers": {
    "salesforce-lite": {
      "command": "uvx",
      "args": [
        "--from",
        "mcp-salesforce-lite",
        "mcp-salesforce-lite"
      ],
      "env": {
        "SALESFORCE_ACCESS_TOKEN": "your_access_token",
        "SALESFORCE_INSTANCE_URL": "your_instance_url"
      }
    }
  }
}

Step 2: Set Up Salesforce Credentials

Replace the environment variables in the configuration:

• SALESFORCE_ACCESS_TOKEN: Your Salesforce access token
• SALESFORCE_INSTANCE_URL: Your Salesforce instance URL (e.g., https://yourcompany.my.salesforce.com)

Step 3: Restart Claude Desktop

After saving the configuration, restart Claude Desktop. You should see a hammer icon indicating that tools are available.

Step 4: Test the Integration

Try asking Claude:

• "List available Salesforce objects"
• "Describe the Account object"
• "Execute a SOQL query to get recent leads"

Prerequisites

• Python 3.10 or higher
• Salesforce Developer/Production org
• Connected App configured in Salesforce

How to Release the Server as a Pip Package

The server can be packaged and distributed via PyPI using the included pyproject.toml configuration.

Available Tools

The server provides the following tools that AI assistants can use:

Query Tools

• soql_query: Execute SOQL queries (schema must be defined to carefully ask for confirmation of UPDATE and DELETE operations)
• search_records: Search records across multiple objects with limit and pagination
• get_record: Retrieve a specific record by ID with limit and pagination

CRUD Operations

• update_record: Update existing records
• delete_record: Delete records

Metadata Tools

• describe_object_definition: Get object metadata and field information with pagination
• list_avail_objects: List available Salesforce objects with limit and pagination
