get_object_fields
AI agents call get_object_fields to retrieve information from MCP Salesforce Connector without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears designed to retrieve field definitions or metadata from Salesforce objects. This is a read-only query operation with no side effects—it retrieves structural information about objects rather than creating, modifying, or deleting records. The lack of a description lowers confidence slightly, but the semantic intent is clear from the name and context among other read/query tools on the server.
From the tool's definition Tool name 'get_object_fields' indicates field retrieval/inspection; no description provided, but naming and sibling context (SOQL, SOSL searches, record retrieval) strongly suggest this queries object schema metadata without modifying data.
