Ahk file DETECT AND SET ACTIVE FILE FOR EDITING - Use this immediately when user mentions any .ahk file path. This enables all other editing tools to work on the specified file. Essential first step before any file modifications.
AI agents use AHK_File_Active 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 itself sets/designates a file as active for editing purposes. While it doesn't directly modify file contents, it enables subsequent modification operations and constitutes a write-class action (state change affecting subsequent operations). It's Write rather than Execute because it's preparatory configuration, not arbitrary code execution.
From the tool's definition Tool description states 'DETECT AND SET ACTIVE FILE FOR EDITING' and 'Essential first step before any file modifications.' This indicates it prepares a file for write operations and enables other editing tools.
Documented attack patterns abuse exactly the kind of access AHK_File_Active 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_File_Active:
{
"version": "1",
"default": "deny",
"tools": {
"AHK_File_Active": {
"limits": [
{
"counter": "ahk_file_active_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}AHK_File_Active 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 file DETECT AND SET ACTIVE FILE FOR EDITING - Use this immediately when user mentions any .ahk file path. This enables all other editing tools to work on the specified file. Essential first step before any file modifications. 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_File_Active: 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_File_Active 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_File_Active 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_File_Active. 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_File_Active 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.
