THE RISK

Medium Risk

Why generate_basic_auth needs a policy

This tool generates (creates) an HTTP Basic Authentication header, which is a reversible write operation. It produces output (an auth header) that can be modified or discarded without permanent side effects. The severity is low because it merely constructs a standard auth header—it does not execute network requests, modify systems, or cause irreversible changes.

From the tool's definition Tool name 'generate_basic_auth' and description 'Generate HTTP Basic Authentication header' indicates creation of authentication credentials in header format.

POLICY

How to control generate_basic_auth

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

policy.json

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

generate_basic_auth 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.

FAQ

Questions about generate_basic_auth

What does the generate_basic_auth tool do? +

Generate HTTP Basic Authentication header. It is categorised as a Write tool in the IT Tools 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 generate_basic_auth? +

Register the IT Tools MCP Server MCP server in PolicyLayer and add a rule for generate_basic_auth: 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 IT Tools MCP Server. Nothing to install.

What risk level is generate_basic_auth? +

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

Can I rate-limit generate_basic_auth? +

Yes. Add a rate_limit block to the generate_basic_auth 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 generate_basic_auth completely? +

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

generate_basic_auth is provided by the IT Tools MCP Server MCP server (wrenchpilot/it-tools-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every IT Tools MCP Server tool call.

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