Why ssh_plan_edit needs a policy

ssh_plan_edit creates a managed plan for editing remote files. Although it requires approval before the actual write occurs, the tool's core function is to prepare file modifications. This falls under Write (create/modify data reversibly) rather than Execute, as it does not run arbitrary commands but specifically targets file content changes.

From the tool's definition The tool description explicitly states it creates a plan 'before writing', indicating it prepares modifications to remote files.

POLICY

How to control ssh_plan_edit

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_plan_edit:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ssh_plan_edit": {
      "limits": [
        {
          "counter": "ssh_plan_edit_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

ssh_plan_edit stays usable, but capped — an agent stuck in a loop can't make hundreds of changes 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_plan_edit

What does the ssh_plan_edit tool do? +

Create a managed remote file edit plan that requires approval before writing. It is categorised as a Write tool in the SSH Remote MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on ssh_plan_edit? +

Register the SSH Remote MCP Server MCP server in PolicyLayer and add a rule for ssh_plan_edit: 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_plan_edit? +

ssh_plan_edit is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit ssh_plan_edit? +

Yes. Add a rate_limit block to the ssh_plan_edit 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_plan_edit completely? +

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

ssh_plan_edit 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.
