List all active terminal sessions.
AI agents call termf_list_sessions to retrieve information from TermPipe MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation to enumerate active terminal sessions. It has no side effects, does not execute commands, and does not modify system state. While the parent server provides dangerous capabilities (direct terminal access), this specific tool is confined to information retrieval.
From the tool's definition Tool name 'list_sessions' and description 'List all active terminal sessions' indicate a query operation that retrieves information about existing sessions without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
List all active terminal sessions. It is categorised as a Read tool in the TermPipe MCP MCP Server, which means it retrieves data without modifying state.
Register the TermPipe MCP server in PolicyLayer and add a rule for termf_list_sessions: 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 TermPipe MCP. Nothing to install.
termf_list_sessions 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 termf_list_sessions 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 termf_list_sessions. 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.
termf_list_sessions is provided by the TermPipe MCP server (wbind-core/termpipe-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
