Why openwrt_opkg_install needs a policy

Installing a package via opkg executes the package manager on the router, which runs installation scripts, modifies the filesystem, and potentially changes system behavior. This is an Execute-level action with high severity because an AI agent could install malicious or unwanted packages on a network router, compromising security of all devices on the network.

POLICY

How to control openwrt_opkg_install

PolicyLayer is an MCP gateway — it sits between your AI agents and OpenWRT SSH MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for openwrt_opkg_install:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "openwrt_opkg_install": {
      "limits": [
        {
          "counter": "openwrt_opkg_install_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

openwrt_opkg_install stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register OpenWRT SSH 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 openwrt_opkg_install

What does the openwrt_opkg_install tool do? +

Install a package using opkg. It is categorised as a Execute tool in the OpenWRT SSH MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on openwrt_opkg_install? +

Register the OpenWRT SSH MCP Server MCP server in PolicyLayer and add a rule for openwrt_opkg_install: 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 OpenWRT SSH MCP Server. Nothing to install.

What risk level is openwrt_opkg_install? +

openwrt_opkg_install is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit openwrt_opkg_install? +

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

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

openwrt_opkg_install is provided by the OpenWRT SSH MCP Server MCP server (jsebgiraldo/openwrt_ssh_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every OpenWRT SSH MCP Server tool call.

Start from OpenWRT SSH MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
