AI agents use AHK_Settings to create or update resources in Ahk — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ahk environment.
The tool modifies settings and feature flags rather than retrieving them, placing it in the Write category. Severity is medium because misconfigured settings could degrade functionality or enable unintended features, but changes are typically reversible.
From the tool's definition Tool description states 'Manage tool settings and enable/disable features' — this involves modifying configuration state and toggling features, which are reversible write operations.
Documented attack patterns abuse exactly the kind of access AHK_Settings gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ahk, and nothing reaches the server without passing your rules. This is the rule we recommend for AHK_Settings:
{
"version": "1",
"default": "deny",
"tools": {
"AHK_Settings": {
"limits": [
{
"counter": "ahk_settings_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}AHK_Settings 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.

Ahk settings Manage tool settings and enable/disable features. It is categorised as a Write tool in the Ahk MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ahk MCP server in PolicyLayer and add a rule for AHK_Settings: 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 Ahk. Nothing to install.
AHK_Settings is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the AHK_Settings 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.
Set action: deny in the PolicyLayer policy for AHK_Settings. 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.
AHK_Settings is provided by the Ahk MCP server (truecrimedev/ahk-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
