Why execute_test_plan needs a policy

This tool performs active execution and deployment operations rather than passive data retrieval or creation. It orchestrates multiple operations (scenario generation and deployment) that modify system state by instantiating mock servers.

From the tool's definition Tool name 'execute_test_plan' combined with description stating it 'Combines scenario generation and deployment in one operation.' The verb 'execute' and 'deployment' indicate the tool runs/triggers external operations (test execution and deployment of mock…

POLICY

How to control execute_test_plan

PolicyLayer is an MCP gateway — it sits between your AI agents and MockLoop MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for execute_test_plan:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "execute_test_plan": {
      "limits": [
        {
          "counter": "execute_test_plan_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

execute_test_plan 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 MockLoop 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.

FAQ

Questions about execute_test_plan

What does the execute_test_plan tool do? +

Combines scenario generation and deployment in one operation. It is categorised as a Execute tool in the MockLoop MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on execute_test_plan? +

Register the MockLoop MCP Server MCP server in PolicyLayer and add a rule for execute_test_plan: 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 MockLoop MCP Server. Nothing to install.

What risk level is execute_test_plan? +

execute_test_plan is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit execute_test_plan? +

Yes. Add a rate_limit block to the execute_test_plan 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.

How do I block execute_test_plan completely? +

Set action: deny in the PolicyLayer policy for execute_test_plan. 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.

What MCP server provides execute_test_plan? +

execute_test_plan is provided by the MockLoop MCP Server MCP server (mockloop/mockloop-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MockLoop MCP Server tool call.

Start from MockLoop MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
