Why utils_installAgentMaster needs a policy

This tool installs software (a CLI tool) on the host system, which constitutes executing an external operation with system-level side effects. Installing software modifies the system state, adds executables, and potentially modifies configuration files across multiple platforms. This goes beyond a simple write operation as it involves running an installer and executing code on the host machine.

POLICY

How to control utils_installAgentMaster

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

policy.json

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

utils_installAgentMaster 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 Bitcoin SV 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.
