MOST DANGEROUS TOOLS

High Risk

The most dangerous Mcp Score tools

Write · Medium add_live_chord_symbol This tool creates or adds a new element (chord symbol) to a musical score, which is a reversible modification. Write · Low add_live_rehearsal_mark Adding a rehearsal mark is a standard music notation editing operation that creates new content in the score. Write · Low disconnect_from_dorico This tool modifies an active connection state by disconnecting from the Dorico music notation application. Write · Low disconnect_from_musescore Disconnecting from MuseScore is a reversible operation that modifies the server's state without destroying data or executing arbitrary code.

13 of Mcp Score's 18 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Mcp Score

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

Rate limit write operations

{
  "add_live_chord_symbol": {
    "limits": [
      {
        "counter": "add_live_chord_symbol_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_live_score_info": {
    "limits": [
      {
        "counter": "get_live_score_info_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
