logging_setLevel

THE RISK

Medium Risk

Why logging_setLevel needs a policy

This tool creates or modifies logging configuration state (the minimum logging level), which is reversible and has no data deletion, code execution, or financial effects. It affects only MCP's internal logging behavior, with minimal blast radius if misconfigured—at worst, logs become over-verbose or under-verbose. Classified as Write rather than Other because it explicitly modifies system state.

From the tool's definition Tool name 'logging_setLevel' and description 'Set the minimum logging level' indicate the tool modifies logging configuration settings.

POLICY

How to control logging_setLevel

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 logging_setLevel:

policy.json

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

logging_setLevel 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.

Create a free account and register IT Tools 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 logging_setLevel

What does the logging_setLevel tool do? +

Set the minimum logging level for MCP logging notifications. Available levels: debug, info, notice, warning, error, critical, alert, emergency. 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 logging_setLevel? +

Register the IT Tools MCP Server MCP server in PolicyLayer and add a rule for logging_setLevel: 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 logging_setLevel? +

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

Can I rate-limit logging_setLevel? +

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

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

logging_setLevel 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.
