THE RISK

High Risk

Why ssh_approve_plan needs a policy

Approving a plan gates the execution of arbitrary SSH commands on remote systems. The act of approval directly enables execution, making this an Execute-category action. The blast radius is critical because the underlying plan could contain any shell commands on remote infrastructure, including destructive or system-altering operations.

From the tool's definition 'Approve a stored plan so it can be executed' - approval triggers execution of previously stored commands on a remote SSH server

POLICY

How to control ssh_approve_plan

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

policy.json

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

ssh_approve_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 SSH Remote 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 ssh_approve_plan

What does the ssh_approve_plan tool do? +

Approve a stored plan so it can be executed. It is categorised as a Execute tool in the SSH Remote 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 ssh_approve_plan? +

Register the SSH Remote MCP Server MCP server in PolicyLayer and add a rule for ssh_approve_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 SSH Remote MCP Server. Nothing to install.

What risk level is ssh_approve_plan? +

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

Can I rate-limit ssh_approve_plan? +

Yes. Add a rate_limit block to the ssh_approve_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 ssh_approve_plan completely? +

Set action: deny in the PolicyLayer policy for ssh_approve_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 ssh_approve_plan? +

ssh_approve_plan is provided by the SSH Remote MCP Server MCP server (nqmn/adremote-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every SSH Remote MCP Server tool call.

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