AI agents call session_list 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.
The tool appears to query and return a list of iTerm2 sessions. This is a read operation with no side effects—it retrieves information without creating, modifying, deleting, or executing commands. The lack of a description lowers confidence slightly, but the semantics of 'list' in this context are unambiguous and point to a safe enumeration operation.
From the tool's definition Tool named 'session_list' with no description provided. The naming convention ('list') and context of an iTerm2 control server strongly indicate this retrieves or enumerates existing sessions without modification.
Attacks that exploit this kind of access
session_list. 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 session_list: 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.
session_list 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 session_list 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 session_list. 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.
session_list 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.
