wbind_action · TermPipe MCP: Risk & Policy

WHAT IT DOES

What wbind_action does on TermPipe MCP

AI agents invoke wbind_action 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 wbind_action needs a policy

The server context involves direct terminal access and command execution. The 'wbind_action' name suggests binding or triggering an action (possibly a hotkey/window binding action, given sibling tools like 'cond_clear_hotkeys'), which on a terminal-access server likely involves executing some action.

From the tool's definition Tool name 'wbind_action' on a server that 'Provides AI assistants with direct terminal access to execute commands, manage files, and run persistent REPL sessions.' The tool description is empty/uninformative.

wbind_action Rate-limited

wbind_action stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
