Why ssh_delete_saved_credentials needs a policy

This tool permanently removes saved SSH credentials from local storage, which cannot be undone without re-saving them. This is a destructive action as it irreversibly deletes data.

From the tool's definition The tool is named 'ssh_delete_saved_credentials' and described as 'Delete a saved local SSH credential entry'. The use of 'Delete' indicates irreversible removal of stored credentials.

POLICY

How to control ssh_delete_saved_credentials

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_delete_saved_credentials:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "ssh_delete_saved_credentials"
  ]
}

ssh_delete_saved_credentials disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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.

How do I block ssh_delete_saved_credentials completely? +

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

ssh_delete_saved_credentials 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.
