Misuse could allow an attacker to hijack an authenticated Salesforce session, making the severity high.

How to control generate_frontdoor_url

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:

policy.json
{
  "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.

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