Narrow the previous scan. scan_type: changed|unchanged|increased|decreased|exact|incby|decby
AI agents call scan_next 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.
Memory scanning is a read-only operation—it examines memory to locate values but does not alter game state or data. While the broader server context includes destructive capabilities (memory writing via 'call_native', 'alloc_cave'), this specific tool only narrows a search based on value changes, making it a Read-category tool. Severity is low because memory scanning alone has no side effects on the game or system.
From the tool's definition The tool name 'scan_next' and description 'Narrow the previous scan' with scan_type options (changed|unchanged|increased|decreased|exact|incby|decby) indicate a memory scanning operation that searches for values matching specified criteria.
Attacks that exploit this kind of access
Narrow the previous scan. scan_type: changed|unchanged|increased|decreased|exact|incby|decby. 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_next: 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_next 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_next 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_next. 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_next 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.
