List all registered terminals.
AI agents call list_terminals to retrieve information from Mcp Terminal Share without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about registered terminals on the local filesystem—it queries state without modifying, deleting, or executing operations. It has minimal blast radius since it only exposes metadata about existing terminal registrations, which is non-sensitive system state in the context of a local development communication channel.
From the tool's definition The tool name is 'list_terminals' and the description states it 'List all registered terminals.' The verb 'list' indicates data retrieval with no side effects.
Attacks that exploit this kind of access
List all registered terminals. It is categorised as a Read tool in the Mcp Terminal Share MCP Server, which means it retrieves data without modifying state.
Register the Mcp Terminal Share MCP server in PolicyLayer and add a rule for list_terminals: 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 Mcp Terminal Share. Nothing to install.
list_terminals 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 list_terminals 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 list_terminals. 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.
list_terminals is provided by the Mcp Terminal Share MCP server (wu-yu-pei/mcp-terminal-share). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
