AI agents call global_search 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.
Global search queries and retrieves existing Salesforce data across multiple objects. It has no side effects—it does not create, modify, delete, or execute operations. While the blast radius could span sensitive CRM data exposure, the tool itself is a passive retrieval mechanism. Severity is low because search exposure is inherent to CRM access; this tool does not amplify risk beyond normal read permissions.
From the tool's definition Tool name 'global_search' and description 'Perform a global search across all Salesforce objects' indicate data retrieval without modification.

Documented attack patterns abuse exactly the kind of access global_search gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Salesforce, and nothing reaches the server without passing your rules. This is the rule we recommend for global_search:
{
"version": "1",
"default": "deny",
"tools": {
"global_search": {}
}
}global_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Perform a global search across all Salesforce objects. 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 global_search: 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.
global_search 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 global_search 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 global_search. 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.
global_search is provided by the Salesforce MCP server (tomnagengast/mcp-server-salesforce). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Salesforce, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
