WHAT IT DOES

What get-config does on Frontmcp

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

RISK

Why get-config is rated Low

This tool retrieves configuration data (environment variables) without creating, modifying, deleting, or executing operations. It is a simple query/fetch operation with minimal blast radius unless sensitive credentials are exposed, but the tool itself performs only information retrieval.

From the tool's definition Tool name 'get-config' and description 'Get an environment variable value with optional default' indicate a read-only retrieval operation. The verb 'Get' and absence of modification language confirm no side effects.

RECOMMENDED RULE

The rule that runs get-config safely

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

get-config Allowed

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get-config": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Frontmcp, apply this rule, and every get-config call is checked against it from then on.
