Describes the available fields for a lead object in Salesforce.
AI agents call describe_lead_schema to retrieve information from Salesforce MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about the structure of a lead object (field names, types, etc.) without creating, modifying, deleting, or executing operations. It is purely informational and read-only, making it a Read category tool with low severity risk.
From the tool's definition Tool name and description indicate it 'Describes the available fields for a lead object' — a schema introspection operation with no data modification or side effects.
