List all active memory watchpoints. Shows watchpoint IDs, address ranges, type (load/store), and status. Related tools: setWatchpoint, deleteBreakpoint, listBreakpoints
AI agents call listWatchpoints 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.
This tool queries and displays information about existing watchpoints in the VICE debugger. It performs no state modifications, does not execute code or commands, does not delete data, and does not involve financial operations. It is purely a read operation that retrieves debugging metadata from the emulator's watchpoint system.
From the tool's definition Tool name 'listWatchpoints' and description 'List all active memory watchpoints. Shows watchpoint IDs, address ranges, type (load/store), and status.' indicate retrieval of existing watchpoint configuration without modification or side effects.

List all active memory watchpoints. Shows watchpoint IDs, address ranges, type (load/store), and status. Related tools: setWatchpoint, deleteBreakpoint, listBreakpoints. 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 listWatchpoints: 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.
listWatchpoints 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 listWatchpoints 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 listWatchpoints. 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.
listWatchpoints 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.
