Load a previously saved machine state from a file. Restores complete machine state including memory, registers, and peripheral states. Warning: This completely replaces the current state! Related tools: saveSnapshot
AI agents call loadSnapshot to retrieve information from VICE C64 Emulator MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though loadSnapshot only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Load a previously saved machine state from a file. Restores complete machine state including memory, registers, and peripheral states. Warning: This completely replaces the current state! Related tools: saveSnapshot. It is categorised as a Read tool in the VICE C64 Emulator MCP Server MCP Server, which means it retrieves data without modifying state.
Register the VICE C64 Emulator MCP Server MCP server in PolicyLayer and add a rule for loadSnapshot: 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.
loadSnapshot is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the loadSnapshot 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.
Set action: deny in the PolicyLayer policy for loadSnapshot. 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.
loadSnapshot 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.
