Why run-apex-tests needs a policy

This tool runs Apex code (via tests) in a Salesforce environment. While test execution is nominally safer than unrestricted Apex execution, tests can still perform writes, external API calls, or other side effects. The tool enables code execution whose effects depend on the test implementations provided as arguments, making it Execute category.

From the tool's definition Tool executes Apex tests, which are code execution operations in Salesforce. The description explicitly states 'Run Apex tests' and the sibling tools include 'execute-apex' and 'execute-soql', confirming this server deals with code execution capabilities.

POLICY

How to control run-apex-tests

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 run-apex-tests:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "run-apex-tests": {
      "limits": [
        {
          "counter": "run-apex-tests_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

run-apex-tests stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. 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.
