reset · VICE C64 Emulator MCP Server MCP: Risk & Policy

WHAT IT DOES

What reset does on VICE C64 Emulator MCP Server

AI agents invoke reset to trigger actions in VICE C64 Emulator MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why reset needs a policy

Resetting the emulator triggers an external operation (machine reset) that affects the running state of the emulated system. A hard reset clears all memory and restarts execution, which is a significant side effect.

Verdict

reset Rate-limited

reset 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.

FAQ

Questions about reset

What does the reset tool do? +

Reset the C64 machine. Options: - hard: If true, performs hard reset (like power cycle). If false, soft reset (like reset button). A soft reset preserves some memory contents, hard reset clears everything. Related tools: connect, status. It is categorised as a Execute tool in the VICE C64 Emulator MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on reset? +

Register the VICE C64 Emulator MCP Server MCP server in PolicyLayer and add a rule for reset: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches VICE C64 Emulator MCP Server. Nothing to install.

What risk level is reset? +

reset is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit reset? +

Yes. Add a rate_limit block to the reset rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block reset completely? +

Set action: deny in the PolicyLayer policy for reset. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides reset? +

reset is provided by the VICE C64 Emulator MCP Server MCP server (simen/vice-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
