List all active breakpoints. Shows breakpoint IDs, addresses, and status for all breakpoints set in this session. Note: This tracks breakpoints set through this MCP session. Breakpoints set through VICE
AI agents call listBreakpoints 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 only queries and returns information about currently active breakpoints. It performs no state modifications, code execution, or destructive operations. It is purely informational and falls clearly into the Read category with low severity since it cannot cause harm if misused—it simply reflects existing debugging configuration.
From the tool's definition Tool name 'listBreakpoints' and description 'List all active breakpoints' with 'Shows breakpoint IDs, addresses, and status' indicates retrieval of existing debugging state with no modification or side effects.

List all active breakpoints. Shows breakpoint IDs, addresses, and status for all breakpoints set in this session. Note: This tracks breakpoints set through this MCP session. Breakpoints set through VICE. 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 listBreakpoints: 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.
listBreakpoints 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 listBreakpoints 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 listBreakpoints. 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.
listBreakpoints 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.
