AI agents call app_version to retrieve information from It2mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves iTerm2 version metadata, which is a read-only operation with no side effects. It does not create, modify, delete, or execute any code. The blast radius if misused is negligible—an AI agent obtaining version information poses minimal risk.
From the tool's definition Tool name 'app_version' and description 'Get the iTerm2 version' indicate a query operation that retrieves version information without modifying or executing any operations.
Attacks that exploit this kind of access
Get the iTerm2 version. It is categorised as a Read tool in the It2mcp MCP Server, which means it retrieves data without modifying state.
Register the It2 MCP server in PolicyLayer and add a rule for app_version: 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 It2mcp. Nothing to install.
app_version 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 app_version 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 app_version. 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.
app_version is provided by the It2 MCP server (urjitbhatia/it2mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
