Get the full schema for a Salesforce object — all fields with types, labels, picklist values, and relationships. Use before constructing queries to know exact field names.
AI agents call salesforce_describe_object to retrieve information from Salesforce without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and returns metadata about Salesforce object structures. It performs read-only introspection with no capability to modify, delete, execute commands, or commit financial transactions. The blast radius of misuse is minimal—an attacker gains knowledge of schema but cannot act on it without separate Write, Execute, or Destructive tools.
From the tool's definition Tool description states: 'Get the full schema for a Salesforce object — all fields with types, labels, picklist values, and relationships.' This is purely a retrieval operation with no mutation or side effects.
Attacks that exploit this kind of access
Get the full schema for a Salesforce object — all fields with types, labels, picklist values, and relationships. Use before constructing queries to know exact field names. It is categorised as a Read tool in the Salesforce MCP Server, which means it retrieves data without modifying state.
Register the Salesforce MCP server in PolicyLayer and add a rule for salesforce_describe_object: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Salesforce. Nothing to install.
salesforce_describe_object is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the salesforce_describe_object rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for salesforce_describe_object. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
salesforce_describe_object is provided by the Salesforce MCP server (wyre-technology/salesforce-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
