WHAT IT DOES

What install_application does on 20i MCP Server

AI agents invoke install_application to trigger actions in 20i MCP Server. 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.

RISK

Why install_application is rated High

Installing an application triggers an external operation that modifies the hosting environment by deploying software. This goes beyond a simple write (data creation/modification) as it executes an installation process with side effects that depend on the application being installed. Misuse could result in malicious or unwanted software being deployed on a hosting package, hence high severity.

RECOMMENDED RULE

The rule that runs install_application safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 20i MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For install_application, this is the rule to start with:

install_application Rate-limited

install_application 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.

The button opens the PolicyLayer dashboard: create your workspace, connect 20i MCP Server, apply this rule, and every install_application call is checked against it from then on.
