WHAT IT DOES

What sobject_describe does on Salesforce MCP Server

AI agents call sobject_describe 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.

THE RISK

Low Risk

Why sobject_describe needs a policy

sobject_describe performs metadata introspection only—it queries and returns information about SObject structure without creating, modifying, deleting, or executing any operations. This is a classic Read operation with minimal risk; exposure would allow information disclosure about org structure but no actionable impact without additional tools.

From the tool's definition Tool retrieves detailed metadata about Salesforce SObjects including fields, relationships, and properties in JSON format with no modification or deletion capability mentioned.

POLICY

How to control sobject_describe

PolicyLayer is an MCP gateway — it sits between your AI agents and Salesforce MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for sobject_describe:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "sobject_describe": {}
  }
}

sobject_describe is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Salesforce MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
