WHAT IT DOES

What read_file does on cPanel MCP Server

AI agents call read_file to retrieve information from cPanel MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why read_file is rated Low

This is fundamentally a Read operation (retrieves data, no side effects), but severity is High rather than Low due to the cPanel context where file contents often contain secrets and sensitive configuration data. An AI agent with unrestricted file_read access could exfiltrate credentials, private keys, and customer data. The confidence is high because the name and description are explicit and unambiguous.

From the tool's definition Tool name 'read_file' with description 'Read the contents of a file' indicates data retrieval without modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs read_file safely

PolicyLayer is an MCP gateway: it sits between your AI agents and cPanel MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For read_file, this is the rule to start with:

read_file Allowed

read_file is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect cPanel MCP Server, apply this rule, and every read_file call is checked against it from then on.
