WHAT IT DOES

What local_config_open does on Omarchy-MCP

AI agents use local_config_open to create or update resources in Omarchy-MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Omarchy-MCP environment.

RISK

Why local_config_open is rated Medium

An AI agent can call local_config_open faster than any human can review: one bad instruction and it creates or modifies resources in Omarchy-MCP by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs local_config_open safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Omarchy-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For local_config_open, this is the rule to start with:

local_config_open Rate-limited

local_config_open 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 local_config_open

What does the local_config_open tool do? +

Open one existing readable local file in a supported configured terminal editor under a deterministic Omarchy app ID, then confirm a new exact-class window. GUI/dynamic editor signatures are refused before launch. No URLs, shell commands, file creation, or installer fallbacks. It is categorised as a Write tool in the Omarchy-MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on local_config_open? +

Register the Omarchy MCP server in PolicyLayer and add a rule for local_config_open: 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 Omarchy-MCP. Nothing to install.

What risk level is local_config_open? +

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

Can I rate-limit local_config_open? +

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

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

local_config_open is provided by the Omarchy MCP server (hlsitechio/Omarchy-MCP). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
