Why connect_to_musescore needs a policy

This tool establishes a connection to an existing MuseScore application instance. It does not read data, write/modify scores, execute code, destroy data, or move money. It is purely a session/handshake operation, making it fit best in 'Other'. Misuse has minimal blast radius — at worst a connection is established unnecessarily.

From the tool's definition Connect to a running MuseScore instance.

POLICY

How to control connect_to_musescore

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "connect_to_musescore": {
      "limits": [
        {
          "counter": "connect_to_musescore_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

connect_to_musescore gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Score — nothing to install.
Add this policy — paste it, or build it visually.
