Ahk active file Get or set the active AHK file path used as a default when invoking tools.
AI agents use AHK_Active_File 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.
This tool allows setting a file path variable, which modifies the runtime state of the AHK system. While the change is reversible and doesn't delete data, it affects subsequent tool invocations by altering a default parameter. This makes it a Write operation.
From the tool's definition The tool 'Get or set the active AHK file path' explicitly permits modification of state via a set operation. The word 'set' indicates reversible write capability to a configuration variable.
Documented attack patterns abuse exactly the kind of access AHK_Active_File 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_Active_File:
{
"version": "1",
"default": "deny",
"tools": {
"AHK_Active_File": {
"limits": [
{
"counter": "ahk_active_file_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}AHK_Active_File 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 active file Get or set the active AHK file path used as a default when invoking tools. 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_Active_File: 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_Active_File 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_Active_File 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_Active_File. 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_Active_File 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.
