openclaw_send_session · LocalAnt MCP: Risk & Policy

WHAT IT DOES

What openclaw_send_session does on LocalAnt

AI agents invoke openclaw_send_session to trigger actions in LocalAnt. 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 openclaw_send_session needs a policy

Sending a message to an external session (OpenClaw) constitutes triggering an external operation whose effects depend on the message content. Given the server context (shell, browser automation), the session could execute arbitrary actions. Confidence is reduced due to the DEPRECATED flag and lack of detail about what OpenClaw is or does.

From the tool's definition 'Send a message to an OpenClaw session' — triggers external operation on a running session; server description mentions 'shell commands, browser automation' context; marked DEPRECATED
