Why run_load_test needs a policy

This tool triggers execution of load testing operations against mock servers. While not destructive or financial, it executes external operations that could generate significant system load, consume resources, create side effects on target systems, or produce unintended consequences if misconfigured by an AI agent. The configurable parameters mean outcome depends on how the agent invokes it.

From the tool's definition Tool name is 'run_load_test' and description states it 'Executes load testing with configurable parameters.' The verb 'executes' combined with 'configurable parameters' indicates this tool runs external operations (load test operations) whose effects depend…

POLICY

How to control run_load_test

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 run_load_test:

policy.json

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

run_load_test 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 run_load_test

What does the run_load_test tool do? +

Executes load testing with configurable parameters. 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 run_load_test? +

Register the MockLoop MCP Server MCP server in PolicyLayer and add a rule for run_load_test: 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 run_load_test? +

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

Can I rate-limit run_load_test? +

Yes. Add a rate_limit block to the run_load_test 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 run_load_test completely? +

Set action: deny in the PolicyLayer policy for run_load_test. 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 run_load_test? +

run_load_test 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.
