MOST DANGEROUS TOOLS

Critical Risk

The most dangerous VICE C64 Emulator MCP Server tools

Destructive · Low deleteBreakpoint Deleting a breakpoint is an irreversible removal of a debugging artifact. Execute · Medium reset Resetting the emulator triggers an external operation (machine reset) that affects the running state of the emulated system. Execute · Medium runTo This tool executes code within the VICE emulator by advancing program execution to a specified memory address. Execute · Medium step The step tool executes CPU instructions in the VICE emulator context.

12 of VICE C64 Emulator MCP Server's 26 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control VICE C64 Emulator MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and VICE C64 Emulator MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "deleteBreakpoint": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "disconnect": {
    "limits": [
      {
        "counter": "disconnect_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "disassemble": {
    "limits": [
      {
        "counter": "disassemble_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Add these rules — paste them, or build them visually. Tune the limits to your setup.

FAQ

Questions about VICE C64 Emulator MCP Server

Can an AI agent delete data through the VICE C64 Emulator MCP Server MCP server? +

Yes. The VICE C64 Emulator MCP Server server exposes 1 destructive tools including deleteBreakpoint. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through VICE C64 Emulator MCP Server? +

The VICE C64 Emulator MCP Server server has 5 write tools including disconnect, saveSnapshot, setBreakpoint. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach VICE C64 Emulator MCP Server.

How many tools does the VICE C64 Emulator MCP Server MCP server expose? +

26 tools across 4 categories: Destructive, Execute, Read, Write. 14 are read-only. 12 can modify, create, or delete data.

How do I enforce a policy on VICE C64 Emulator MCP Server? +

Register the VICE C64 Emulator MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every VICE C64 Emulator MCP Server tool call.

Deterministic rules across all 26 VICE C64 Emulator MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
