AI agents call generate_frontdoor_url 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 reads/generates a URL containing a live session access token (sid). While it only produces a URL and doesn't directly modify data, the generated URL embeds a valid Salesforce session token that grants full authenticated access to the org. Misuse could allow an attacker to hijack an authenticated Salesforce session, making the severity high.

Documented attack patterns abuse exactly the kind of access generate_frontdoor_url gives an agent:
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 generate_frontdoor_url:
{
"version": "1",
"default": "deny",
"tools": {
"generate_frontdoor_url": {}
}
} generate_frontdoor_url is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
