MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Commodore 64 Ultimate Computer MCP Server tools

Destructive · High reset_config_to_default Resetting configuration to factory defaults irreversibly overwrites all current settings and customizations. Destructive · High machine_poweroff Powering off a machine is an irreversible immediate action that terminates all running processes and active state. Execute · Medium drive_reset Resetting a drive triggers an external hardware operation on the C64 device. Execute · Medium machine_reset Sending a reset signal triggers an external hardware operation (resetting the Commodore 64 machine), which is an execution/trigger action.

40 of Commodore 64 Ultimate Computer MCP Server's 54 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Commodore 64 Ultimate Computer MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and Commodore 64 Ultimate Computer MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "reset_config_to_default": {
    "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

{
  "drive_remove": {
    "limits": [
      {
        "counter": "drive_remove_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_config_category": {
    "limits": [
      {
        "counter": "get_config_category_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

For control keys that can Execute sidplay_file Play a SID file located on the Commodore 64 Ultimate filesystem Execute sidplay_upload Upload and play a SID file (pure base64 or data URL encoded) from the Commodore 64 Ultimate filesystem Execute type_text Type text into the C64 keyboard buffer. Converts ASCII to PETSCII and writes to the keyboard buffer at $0277. Execute write_debug_register Write debug register (U64 only) Execute write_memory Write data to C64 memory via DMA

WRITE 17 tools

Write drive_remove Unmount disk image from drive Write drive_load_rom_upload Upload and load custom ROM for drive (base64 or data URL encoded) from the Commodore 64 Ultimate filesystem Write load_prg_file Load a program file from filesystem without executing Write load_prg_upload Upload and load a program file without executing (base64 or data URL encoded) from the Commodore 64 Ultimate f Write batch_set_config Set multiple configuration items at once Write create_d64 Create a new D64 disk image Write create_d71 Create a new D71 disk image Write create_d81 Create a new D81 disk image Write create_dnp Create a new DNP disk image Write drive_off Disable a drive Write drive_on Enable a drive Write drive_set_mode Change drive type (1541/1571/1581) Write mount_disk_file Mount a disk image from filesystem Write mount_disk_upload Upload and mount a disk image (base64 or data URL encoded) on the Commodore 64 Ultimate Write save_config_to_flash Save current configuration to non-volatile memory Write set_config_item Set a specific configuration item Write write_memory_binary Write binary data to C64 memory via DMA (base64 or data URL encoded)

READ 14 tools

Read get_config_category Get all configuration items in a category Read get_config_item Get a specific configuration item Read get_file_info Get metadata about a file on the Commodore 64 Ultimate device Read get_screen_mode Detect and return the currently active C64 screen mode and memory configuration. Reads CIA2 ($DD00) and VIC re Read get_version Get the REST API version number from the Commodore 64 Ultimate Computer device Read list_config_categories List all configuration categories Read list_drives Get information about all floppy drives and mounted images Read load_config_from_flash Restore configuration from non-volatile memory Read read_debug_register Read debug register (U64 only) Read read_memory Read data from C64 memory Read capture_all_screen_modes Capture screenshots for all valid C64 screen modes at once. Returns multiple images, one for each mode (standa Read capture_screen Capture the C64 screen as a PNG image. Auto-detects the active graphics mode and renders accordingly. Supporte Read capture_screen_with_config Capture the C64 screen using explicit mode AND memory addresses. Bypasses VIC-II register detection entirely. Read capture_screen_with_mode Capture the C64 screen using an explicit screen mode, ignoring the active VIC-II mode. Useful when auto-detect

FAQ

Questions about Commodore 64 Ultimate Computer MCP Server

Can an AI agent delete data through the Commodore 64 Ultimate Computer MCP Server MCP server? +

Yes. The Commodore 64 Ultimate Computer MCP Server server exposes 2 destructive tools including reset_config_to_default, machine_poweroff. 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 Commodore 64 Ultimate Computer MCP Server? +

The Commodore 64 Ultimate Computer MCP Server server has 17 write tools including drive_remove, drive_load_rom_upload, load_prg_file. 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 Commodore 64 Ultimate Computer MCP Server.

How many tools does the Commodore 64 Ultimate Computer MCP Server MCP server expose? +

54 tools across 4 categories: Destructive, Execute, Read, Write. 14 are read-only. 40 can modify, create, or delete data.

How do I enforce a policy on Commodore 64 Ultimate Computer MCP Server? +

Register the Commodore 64 Ultimate Computer 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 Commodore 64 Ultimate Computer MCP Server tool call.

Deterministic rules across all 54 Commodore 64 Ultimate Computer MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
