termf_live_exec · TermPipe MCP: Risk & Policy

WHAT IT DOES

What termf_live_exec does on TermPipe MCP

AI agents invoke termf_live_exec to trigger actions in TermPipe MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why termf_live_exec needs a policy

The server explicitly provides 'direct terminal access to execute commands' and the tool name ends in 'exec', strongly suggesting this tool executes terminal commands live. Even with an empty description, the naming convention and server context indicate arbitrary command execution capability, which carries critical blast radius if misused by an AI agent.

From the tool's definition Tool name 'termf_live_exec' combined with server description: 'direct terminal access to execute commands' — 'exec' suffix strongly implies execution. Server context makes this a terminal execution tool.
