THE RISK

Low Risk

Why ssh_version needs a policy

This tool only retrieves version and build metadata about the server itself. It has no side effects, does not modify any data, and cannot be misused to cause harm. Pure read/informational operation.

POLICY

How to control ssh_version

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ssh_version": {}
  }
}

ssh_version is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register SSH 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_version

What does the ssh_version tool do? +

Get SSH MCP server version and build information. It is categorised as a Read tool in the SSH MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on ssh_version? +

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

What risk level is ssh_version? +

ssh_version is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit ssh_version? +

Yes. Add a rate_limit block to the ssh_version 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_version completely? +

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

ssh_version is provided by the SSH MCP Server MCP server (lightspeeddms/ssh-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 MCP Server tool call.

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