First scan to find an unknown address. vtype: i8/u8/i16/u16/i32/u32/i64/u64/f32/f64.
AI agents call scan_first to retrieve information from GTAV-CLAUDE-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a memory scan (like Cheat Engine's first scan) to find memory addresses matching certain criteria. It reads memory without modifying it, placing it in the Read category. However, it has medium severity because it's a reconnaissance step that enables subsequent memory writes or exploits; on its own it only reads/queries game memory.
From the tool's definition 'First scan to find an unknown address' — this is a memory scanning/search operation that reads process memory to locate values

First scan to find an unknown address. vtype: i8/u8/i16/u16/i32/u32/i64/u64/f32/f64. It is categorised as a Read tool in the GTAV-CLAUDE-MCP MCP Server, which means it retrieves data without modifying state.
Register the GTAV-CLAUDE- MCP server in PolicyLayer and add a rule for scan_first: 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 GTAV-CLAUDE-MCP. Nothing to install.
scan_first 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 scan_first 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 scan_first. 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.
scan_first is provided by the GTAV-CLAUDE- MCP server (tabbedscamper/gtav-claude-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
