View the bridge's undo stack of recent writes (single source of truth).
AI agents call get_undo_stack 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 retrieves historical information about previous write operations from an undo stack. It has no side effects—it only reads and displays data about past actions. The undo stack itself is metadata tracking changes, not an interactive control. Therefore, it falls squarely into the Read category with low severity, as misuse would only expose information about prior modifications rather than causing new harm.
From the tool's definition Tool name is 'get_undo_stack' with description 'View the bridge's undo stack of recent writes'. The verb 'View' and 'get_' prefix indicate retrieval/query of data without modification.
Attacks that exploit this kind of access
View the bridge's undo stack of recent writes (single source of truth). 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 get_undo_stack: 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.
get_undo_stack 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 get_undo_stack 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 get_undo_stack. 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.
get_undo_stack 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.
