Capture the current VICE display as image data. Returns the raw display buffer with: - Pixel data (indexed 8-bit palette colors) - Display dimensions and visible area - Current palette RGB values The data can be used to understand what
AI agents call screenshot 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 is a read-only operation that retrieves visual state from the emulator for inspection purposes. It has no side effects, creates no modifications to the emulated system, executes no code, and poses minimal risk. The worst-case misuse would be information disclosure of what is currently displayed on the C64 screen, which is low severity.
From the tool's definition The tool 'screenshot' captures the current VICE display as image data, returning pixel data, display dimensions, and palette information.

Capture the current VICE display as image data. Returns the raw display buffer with: - Pixel data (indexed 8-bit palette colors) - Display dimensions and visible area - Current palette RGB values The data can be used to understand what. 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 screenshot: 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.
screenshot 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 screenshot 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 screenshot. 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.
screenshot 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.
