lctx_upgrade · Logica Context MCP: Risk & Policy

WHAT IT DOES

What lctx_upgrade does on Logica Context

AI agents invoke lctx_upgrade to trigger actions in Logica Context. 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 lctx_upgrade needs a policy

Installing software updates is an Execute-category action: it runs external processes to download and apply changes to the installed software. This carries high severity because an AI agent misusing this tool could trigger unintended software changes, potentially installing untested or incompatible versions, or being exploited to install malicious updates if the update source is compromised.

From the tool's definition "Check for and install updates to Logica Context" — the tool installs software updates, which executes installation processes on the system

lctx_upgrade Rate-limited

lctx_upgrade 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.
