THE RISK

Why ssh-test needs a policy

SSH connectivity testing involves establishing a network connection to a remote host, which is an Execute-category action. Even a 'test' SSH operation executes code on or communicates with a remote system, and misuse could be used to probe internal networks, exfiltrate data, or pivot to other systems. The description is truncated/incomplete, slightly lowering confidence, but the core action is clear.

From the tool's definition 'Tests SSH connectivity to a remote host' — initiates an SSH connection to an external host, which is an external network operation/execution

Documented attack patterns abuse exactly the kind of access ssh-test gives an agent:

POLICY

How to control ssh-test

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ssh-test": {
      "limits": [
        {
          "counter": "ssh-test_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

ssh-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 Make — 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 ssh-test

What does the ssh-test tool do? +

Tests SSH connectivity to a remote host using. It is categorised as a Execute tool in the Make MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on ssh-test? +

Register the Make MCP server in PolicyLayer and add a rule for ssh-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 Make. Nothing to install.

What risk level is ssh-test? +

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

Can I rate-limit ssh-test? +

Yes. Add a rate_limit block to the ssh-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 ssh-test completely? +

Set action: deny in the PolicyLayer policy for ssh-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 ssh-test? +

ssh-test is provided by the Make MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Make tool call.

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